Angular - On Paste Event Get Content : <p>I have an angular component that allows a user to enter data into a <code>textarea</code>. There are two events tied to this <code>keydown</code> and <code>paste</code>. Both of these events trigger the same method which will try and determine the data entered.</p>
<p>The issue I am having is when the data is pasted <code>paste</code>, I am getting the value of the <code>formControl</code> but its the value BEFORE the data is pasted and doesn't include what I actually just entered into the field.</p>
<p><strong>HTML</strong></p>
<pre><code><textarea
formControlName="multiSearch"
class="form-control"
placeholder="Enter one or more values. One per line."
rows="6"
(keydown)="keyDownFunction($event)"
(paste)="onPaste()">
</textarea>
</code></pre>
<p><strong>Component</strong></p>
<pre><code> /**
* If we hit enter in our text area, determine the data type
*/
keyDownFunction(event) {
// Enter Key?
if (event.keyCode == 13) {
this.determineDataType();
}
}
/**
* If we paste data in our text area, determine the data type
*/
onPaste() {
this.determineDataType();
}
/**
* Using regex, determine the datatype of the data and confirm with the user.
*/
determineDataType() {
console.log(this.searchForm.value.multiSearch)
}
</code></pre>
<p><strong>Question</strong>
How can I get access to the data that is pasted into the form as soon as the <code>paste</code> event is fired and not what the value was before pasting?</p>

if (getCheapestFruit() == null){
setCheapestFruit(name, price);
System.out.println("CHEAPEST NAME/PRICE INITIALIZED");
} else {
if(getCheapestFruit().price> price){
setCheapestFruit(name, price);
System.out.println("CHEAPEST NAME/PRICE SET");

<p>And I want to set the cheapestFruit.</p>
<pre><code>public Fruit cheapestFruit = null;
public Fruit getCheapestFruit(){
return this.cheapestFruit;

Is this explanation of ternary operator valid? : <p><strong>Question:</strong></p>
<ul>
<li>I want to know if this explanation of the ternary operator is valid.</li>
</ul>
<blockquote>
<p>var = (condition) ? set value if condition one : set value of condition two;</p>
</blockquote>
<p>If the condition is something than the value of the variable will be something. If it's not the value will be different. Basically assign a variable with a value based on a condition. Is this explanation valid? I need to know this if I'm understanding this correctly.</p>

C# How to add a property setter in derived class? : <p>I have a requirement where I have a number of classes all derived from a single base class. The base class contains lists of child classes also derived from the same base class.</p>
<p>All classes need to be able to obtain specific values which may be obtained from the class itself -OR- it's parent depending on what the derived class is.</p>
<p>I looked at using Methods rather than properties however I also want to make the values available to a .NET reporting component which directly accesses exposed public properties in the reporting engine so this excludes the use of methods.</p>
<p>My question is what would be the 'best practices' method of implementing a setter in DerivedClass without having a publicly available setter in BaseClass</p>
<pre><code>public class BaseClass
{
private BaseClass _Parent;
public virtual decimal Result
{
get { return ((_Parent != null) ? _Parent.Result : -1); }
}
}
public class DerivedClass : BaseClass
{
private decimal _Result;
public override decimal Result
{
get { return _Result; }
// I can't use a setter here because there is no set method in the base class so this throws a build error
//set { _Result = value; }
}
}
</code></pre>
<p>I can't add a protected setter (as follows) in BaseClass as I cannot change access modifiers in DerivedClass.</p>
<pre><code>public class BaseClass
{
private BaseClass _Parent;
public virtual decimal Result {
get { return ((_Parent != null) ? _Parent.Result : -1); }
protected set { }
}
}
public class DerivedClass : BaseClass
{
private decimal _Result;
public override decimal Result
{
get { return _Result; }
// This setter throws a build error because of a change of access modifiers.
//set { _Result = value; }
}
}
</code></pre>
<p>I don't want to add a member variable in BaseClass with a setter as I do not want the ability to set the property from the BaseClass or other classes that derive from base.</p>
<pre><code>public class BaseClass
{
private BaseClass _Parent;
protected Decimal _Result; // This could result in a lot of unnecessary members in BaseClass.
public virtual decimal Result {
get { return _Result; }
// Empty setter ahead :) This does nothing.
// I could also throw an exception here but then issues would not be found until runtime
// and could cause confusion in the future with new developers etc.
set { }
}
}
public class DerivedClass : BaseClass
{
public override decimal Result
{
get { return base.Result; }
set { base._Result = value; }
}
}

How to adjust the size of a view at the top of UITableView programatically? : <p>I have a UITableVIew in my app with views holding content at the top and bottom. These obviously scroll out of frame when the user scrolls which is the desired behaviour. </p>
<p>Depending on user inputs I'd like to hide half of the topView but I can't edit the height of that view directly for some reason. I don't know why. I can drag it in Interface Builder but can't edit it programatically. The debugger tells me it's a read only value. </p>
<p>I can get half way there by editing the height of the inner view (statusView) but it then leaves a gap between the end of the topView and the table cells. </p>
<p>Any suggestions?</p>

Extract rows having the 11th column values lies between 1st and 2nd of a second file : Hello I have two files
file1 :
11th column
chromosome position another.... tag name.....score ..... sum
chr1 816 ..... 2456.50
chr1 991 ..... 50345
chr2 816 ..... 2456.50
chr2 880 ..... 78939
chr2 18768 ..... 678909
...
chr5 9736286 .... 78905
file2
chromosome start end ..... ..... .....
chr1 2450 2460
chr2 50340 50350
chr2 678900 678920
chr5 9736280 9736290
I'm interested in printing rows from file 1 using a python code if the values of 11th column falls within the range start and end (2nd and 3rd columns )declared in the seconds file. As the position is only unique within a certain chromosome (chr) first it has to be tested if the chr's are identical... hence my desired output is
chromosome position another.... tag name.....score ..... sum
chr1 816 ..... 2456.50
chr2 18768 ..... 678909
chr5 9736286 .... 78905
I have tried awk codes.. it works perfectly fine but they are very very slow !
The files I'm testing ( from which I need to print the rows are around 4 GB ).
I would highly appreciate if I can have some python code
Thanks !

Whats the right way to separate model and logic : <p>Hi I'm setting up a new project and was struggeling with Java Annotations.
Are they related to Logic / API or Model</p>
<h2>In Detail:</h2>
<p>I have a started a multi maven module for example:</p>
<ul>
<li>project-parent</li>
<li>project-model</li>
<li>project-persist</li>
<li>project-logic1</li>
</ul>
<p>I separated model from every other module simple POJOs with JPA.
To use them with different frontends or REST etc.
Now I wanna use annotations from <strong>project-logic1</strong> in the model.</p>
<p>Now i'm confused with the seperation.</p>
<ul>
<li>Should I make an own API module (<strong>project-API</strong>) for this and similar annotation / interfaces</li>
<li>Should I simply add the annotation in the <strong>project-model</strong></li>
<li>Should I add the dependency of <strong>project-logic1</strong> into the <strong>project-model</strong> POM</li>
</ul>
<p>I think the first one is correctly but I'm not sure.</p>

can you assign initial value to global static variable in C? : <p>I have a global variable "count". All I want to do is increment it each time the loop runs. Is there a potential problem with initializing static count as 0? How is this works in C?</p>
<pre><code>static unsigned short count = 0;
while(1)
{
count++;
// do something
}

AWS Java S3 Uploading error: "profile file cannot be null" : <p>I get an exception when trying to upload a file to Amazon S3 from my Java Spring application. The method is pretty simple:</p>
<pre><code>private void productionFileSaver(String keyName, File f) throws InterruptedException {
String bucketName = "{my-bucket-name}";
TransferManager tm = new TransferManager(new ProfileCredentialsProvider());
// TransferManager processes all transfers asynchronously,
// so this call will return immediately.
Upload upload = tm.upload(
bucketName, keyName, new File("/mypath/myfile.png"));
try {
// Or you can block and wait for the upload to finish
upload.waitForCompletion();
System.out.println("Upload complete.");
} catch (AmazonClientException amazonClientException) {
System.out.println("Unable to upload file, upload was aborted.");
amazonClientException.printStackTrace();
}
}
</code></pre>
<p>It is basically the same that amazon provides <a href="http://docs.aws.amazon.com/AmazonS3/latest/dev/HLuploadFileJava.html" rel="noreferrer">here</a>, and the same exception with the exactly same message ("profile file cannot be null") appears when trying <a href="http://docs.aws.amazon.com/AmazonS3/latest/dev/UploadObjSingleOpJava.html" rel="noreferrer">this other</a> version.
The problem is not related to the file not existing or being null (I have already checked in a thousand ways that the File argument recieved by <code>TransferManager.upload</code> method exists before calling it).</p>
<p>I cannot find any info about my exception message "<strong>profile file cannot be null</strong>". The first lines of the error log are the following:</p>
<pre><code>com.amazonaws.AmazonClientException: Unable to complete transfer: profile file cannot be null

Having an issue with simple account checking program? Program returns compiling error that states "no match for 'operator||' unsure of how to fix?" : <p>I'm new to programming and so I bought a book to help me learn C++, in the book it asks me to do a practice assignment where I must create a program that allows me to take input of multiple usernames and passwords, match them, and also allow someone who incorrectly enters information to try entering it again. I've wrote the following program in order to do so. If anyone can also shed any light on how to make the program allow for retry of username/password entry without ending the program that would also be greatly appreciated. Thank you!</p>
<pre><code>#include <iostream>
#include <string>
using namespace std;
int main()
{
string username1="Varun";
string username2="Agne";
string username3="Geetha";
string username4="Mohan"; //Usernames for accounts
string pass1="PassworD";
string pass2="PASSWORD"; //Passwords for accounts
string pass3="password";
string pass4="Password";
string Uattempt; //User input for username
string Pattempt; //User input for password
cout << "Please enter your username.\n";
cin >> Uattempt;
cout << "Please enter your password \n"; //Asks for username and password entry by user
cin >> Pattempt;
if(Uattempt!=username1 || username2 || username3 || username4)
{
cout << "Access Denied. Incorrect username or password. Please retry.\n"; //If username does not match possible entries, program will ask to retry
}
if(Pattempt !=(pass1||pass2)&&(pass3||pass4)
{
cout << "Access Denied. Incorrect username or password. Please retry.\n"; //If password does not match possible entries, program will ask to retry

Output problem - with itertools.groupby in pyton : I got this homework question, after taking a course on udemy I still cannot figure out how to get the right output like the Solution.
furthermore:
and how can i make it more efficace
how can i do it without use explicit loops, but use list/dictionary comprehensions instead.
this is what i do:
def group_permutation_values(permutations_list):
dic = {}
f = lambda x: x[1]
for key, group in itertools.groupby(sorted(permutations_list, key=f), f):
dic[key] = list(group)
return dic
pass
results = [((1, 2, 3), -4), ((1, 3, 2), -4), ((2, 1, 3), -2), ((2, 3, 1), -2), ((3, 1, 2), 0), ((3, 2, 1), 0)]
print(group_permutation_values(results))
this is what i got :
{-4: [((1, 2, 3), -4), ((1, 3, 2), -4)], -2: [((2, 1, 3), -2), ((2, 3, 1), -2)], 0: [((3, 1, 2), 0), ((3, 2, 1), 0)]}
and the expect output:
{-4: [(1, 2, 3), (1, 3, 2)], -2: [(2, 1, 3), (2, 3, 1)], 0: [(3, 1, 2), (3, 2, 1)]} | 0debug |

find primers and palindromes in python : A palindromic prime is a prime number that is also palindromic.
For example, 131 is a prime and also a palindromic prime, as are 313 and 757.
I need to write a function that displays the first n palindromic prime numbers.
Display 10 numbers per line and align the numbers properly, as follows:
2 3 5 7 11 101 131 151 181 191
313 353 373 383 727 757 787 797 919 929
my code is:
def paliPrime(n):
a=0
b=n
a+=1
for i in range(a,b):
paliPrime=True
if str(i) == str(i)[::-1]:
if i>2:
for a in range(2,i):
if i%a==0:
paliPrime=False
break
if paliPrime:
print i
the code works but not in the way i wanted:
>>>
>>> paliPrime(10)
3
5
7
>>>
And what I want is a function that displays the first n palindromic prime numbers. It should display 10 numbers per line and align the numbers properly. | 0debug |
React redux application folder structure : <p>I understand the concept of a react/redux app.</p>
<p>My question is, is there a preferred way to layout the folder structure and files.</p>
<p>After doing much research of repos online it appears that everyone does it slightly differently depending on their code flavor.</p>
<p>Angular on the other hand appears that there is a set structure.</p>
<p>Is this what makes react more powerful as you can tweak and adjust as your needs change?</p>

Does Rust have Collection traits? : <p>I'd like to write a library that's a thin wrapper around some of the functionality in <a href="https://doc.rust-lang.org/std/collections/btree_map/struct.BTreeMap.html">BTreeMap</a>. I'd prefer not to tightly couple it to that particular data structure though. Strictly speaking, I only need a subset of its functionality, something along the lines of the <a href="https://docs.oracle.com/javase/7/docs/api/java/util/NavigableMap.html">NavigableMap</a> interface in Java. I was hoping to find an analogous trait I could use. I seem to recall that at some point there were traits like <code>Map</code> and <code>MutableMap</code> in the standard library, but they seem to be absent now.</p>
<p>Is there a crate that defines these? Or will they eventually be re-added to std?</p>

A particolar :hoover effect : I'm currently working on this [website][1], in the project section there are 3 columns, i already set the scale to change when hoovering over one of it, but my client requested that the middle column need to be already scaled when the page is opened for the first time, and after hoovering on the one on the left or on the right, the middle column get back to the original scale, the same as the other.
Is possible?
the correct way should be:
0= Original scale
1= Bigger scale
First view of the page->[ 0| 1 |0 ] --hoovering in another column-->[ 1| 0 |0 ] --not hoovering in a column->[ 0| 0 |0 ]
I don't know if i was clear enough, sorry for my english but is not my mother tongue.
Thanks for helping.

SQL server - Using self join/Inner join get the data by adding all the above rows data : I need urgent help with reference to SQL server, the query details is as mentioned below:
Need to get the calculative column whose result will be addition of all the above rows. And I can't use correlated queries, Lag and Lead as it is not supported.
I tried using Selfjoin/inner join/left outer join, the only problem I am facing is due to group by clause of other columns the result is not coming as expected..
For example,
Data is like
[Data is like this image][1]
Expected Output
[Expected output is like this image][2]
But the output I am getting due to group by clause applied on Column4
[Output getting is like][3]
Please let me know some alternative of GROUP by clause or other alternative.
Your quick help will be much appreciated.

Should I make two versions of one program, each with different language, or add an option to change language? : <p>I have a program that I'm currently writing in English. In future, I would like to make the program multilingual, therefore I'm wondering what's the best option to do so. I thought about this two option for now:</p>
<ol>
<li>Enable users to change language in settings;</li>
<li>Select the appropriate language while downloading;</li>
</ol>
<p>With each option comes a problem:</p>
<ol>
<li>A ton of code dedicated to displaying one message in different languages;</li>
<li>I will have to make many versions just to change the language of the displayed text;</li>
</ol>
<p>Now my question is, which one of these options is more memory efficient and user friendly? Maybe neither of them are? Do you have any other option that is better than given two? </p>

Why should forEach be preferred over regular iterators? : <p>I was reading <a href="https://github.com/airbnb/javascript" rel="noreferrer">airbnb javascript guide</a>. There is a particular statement, that says:</p>
<blockquote>
<p>Don’t use iterators. Prefer JavaScript’s higher-order functions instead of loops like for-in or for-of.</p>
</blockquote>
<p>The reason they give for the above statement is:</p>
<blockquote>
<p>This enforces our immutable rule. Dealing with pure functions that return values is easier to reason about than side effects.</p>
</blockquote>
<p>I could not differentiate between the two coding practices given:</p>
<pre><code> const numbers = [1, 2, 3, 4, 5];
// bad
let sum = 0;
for (let num of numbers) {
sum += num;
}
sum === 15;
// good
let sum = 0;
numbers.forEach((num) => {
sum += num;
});
sum === 15;
</code></pre>
<p>Could anyone explain, why should <code>forEach</code> be preferred over regular <code>for</code> loop? How does it really make a difference? Are there any side effects of using the regular <code>iterators</code>?</p>

Warning! ***HDF5 library version mismatched error*** python pandas windows : <p>I'm using pandas/python to save a DataFrame in a HDFStore format. When I apply the <em>my_data_frame.to_hdf(arguments...)</em> command I have an error message:<strong>Warning! ***HDF5 library version mismatched error</strong> *** and my program is stopped.</p>
<p>I'm working on Windows 7 (64bits), using Python 3.5.2 :: Anaconda 4.1.1 (64-bit).</p>
<p>I've been reading about this error message and as it says it's a problem between the version of HDF5 installed on my computer and the one used by Anacondas. According <a href="https://github.com/h5py/h5py/issues/853" rel="noreferrer">this</a> post, a simple <strong><em>"conda install -c anaconda hdf5=1.8.18"</em></strong> could resolve my problem but I'm still having the same message error.</p>
<p>Thanks for your help guys.</p>
<p>Here I put a complete log of the error:</p>
<pre>
Warning! ***HDF5 library version mismatched error***
The HDF5 header files used to compile this application do not match
the version used by the HDF5 library to which this application is linked.
Data corruption or segmentation faults may occur if the application continues.
This can happen when an application was compiled by one version of HDF5 but
linked with a different version of static or shared HDF5 library.
You should recompile the application or check your shared library related
settings such as 'LD_LIBRARY_PATH'.
You can, at your own risk, disable this warning by setting the environment
variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'.
Setting it to 2 or higher will suppress the warning messages totally.
Headers are 1.8.15, library is 1.8.18

<pre><code>export interface MyCustomType {
index: number;
value: string;
}
</code></pre>
<p>I then attempt to import this type so that it can be used in another file:</p>

<p>However, Atom reports the following error:</p>
<pre><code>TS Error File '/.../mycustom.type.ts' is not a module ...

<p>How should I be declaring and importing types, so that they can be used in multiple places?</p>

Pass through authentication with ASP Core MVC, Web API and IdentityServer4? : <p>I have been working on migrating a monolithic ASP Core MVC application to use an service architecture design. The MVC front-end website uses an <code>HttpClient</code> to load necessary data from the ASP Core Web API. A small portion of the front-end MVC app also requires authentication which is in place using IdentityServer4 (integrated with the back-end API). This all works great, until I put an <code>Authorize</code> attribute on a controller or method on the Web API. I know I need to somehow pass the user authorization from the front-end to the back-end in order for this to work, but I'm not sure how. I have tried getting the access_token: <code>User.FindFirst("access_token")</code> but it returns null. I then tried this method and I am able to get the token:</p>
<pre><code>var client = new HttpClient("url.com");
var token = HttpContext.Authentication.GetTokenAsync("access_token")?.Result;
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
</code></pre>
<p>This method gets the token but still doesn't authentication with the back-end API. I'm pretty new to this OpenId/IdentityServer concepts and any help would be appreciated!</p>
<p>Here is the relevant code from the MVC Client Startup class:</p>
<pre><code> private void ConfigureAuthentication(IApplicationBuilder app)
{
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationScheme = "Cookies",
AutomaticAuthenticate = true,
ExpireTimeSpan = TimeSpan.FromMinutes(60)
});
JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
{
AuthenticationScheme = "oidc",
SignInScheme = "Cookies",
Authority = "https://localhost:44348/",
RequireHttpsMetadata = false,
ClientId = "clientid",
ClientSecret = "secret",
ResponseType = "code id_token",
Scope = { "openid", "profile" },
GetClaimsFromUserInfoEndpoint = true,
AutomaticChallenge = true, // Required to 302 redirect to login
SaveTokens = true,
TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
{
NameClaimType = "Name",
RoleClaimType = "Role",
SaveSigninToken = true
},
});
}
</code></pre>
<p>and the StartUp class of the API:</p>
<pre><code> // Add authentication
services.AddIdentity<ExtranetUser, IdentityRole>(options =>
{
// Password settings
options.Password.RequireDigit = true;
options.Password.RequiredLength = 8;
options.Password.RequireNonAlphanumeric = true;
options.Password.RequireUppercase = true;
options.Password.RequireLowercase = true;
// Lockout settings
options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
options.Lockout.MaxFailedAccessAttempts = 10;
// User settings
options.User.RequireUniqueEmail = true;
})
.AddDefaultTokenProviders();
services.AddScoped<IUserStore<ExtranetUser>, ExtranetUserStore>();
services.AddScoped<IRoleStore<IdentityRole>, ExtranetRoleStore>();
services.AddSingleton<IAuthorizationHandler, AllRolesRequirement.Handler>();
services.AddSingleton<IAuthorizationHandler, OneRoleRequirement.Handler>();
services.AddSingleton<IAuthorizationHandler, EditQuestionAuthorizationHandler>();
services.AddSingleton<IAuthorizationHandler, EditExamAuthorizationHandler>();
services.AddAuthorization(options =>
{
/* ... etc .... */
});
var serviceProvider = services.BuildServiceProvider();
var serviceSettings = serviceProvider.GetService<IOptions<ServiceSettings>>().Value;

Is there a <wbr> equivalent tag to affect whole sentences instead of just a single word? : `<wbr>` breaks a word in case of word-wrap due to a small screen.
But is there a tag that could be used in order to break and "word-wrap" the text of a sentence on a specific point in case of a small screen?
The CSS question tag is probable irrelevant, but I thought that maybe someone could have implemented a solution using CSS. | 0debug |

I know, using multiple like operator, we can perform operation using below query
"SELECT * FROM TABLE_1 WHERE bookname like 'Harry Potter' or like 'Heaven world'";
In this case, i want to perform this in a single query. Also i tried with FREETEXT options. That wont be useful when i use self-join. Kindly provide me any other alternatives to solve this.

How to set up filter chain in spring boot? : <p>I have come across spring-boot and intend to add a filter chain for incoming request.</p>
<p>Here is the Application:</p>
<pre><code>package example.hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
}
</code></pre>
<p>Here is the Controller:</p>
<pre><code>package example.hello;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import java.util.concurrent.atomic.AtomicLong;
@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping("/greeting")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
}
</code></pre>
<p>Here is the Filter Config:</p>
<pre><code>package example.hello;
import org.springframework.boot.context.embedded.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class WebConfig {
@Bean
public FilterRegistrationBean greetingFilterRegistrationBean() {
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
registrationBean.setName("greeting");
GreetingFilter greetingFilter = new GreetingFilter();
registrationBean.setFilter(greetingFilter);
registrationBean.setOrder(1);
return registrationBean;
}
@Bean
public FilterRegistrationBean helloFilterRegistrationBean() {
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
registrationBean.setName("hello");
HelloFilter helloFilter = new HelloFilter();
registrationBean.setFilter(helloFilter);
registrationBean.setOrder(2);
return registrationBean;
}
}
</code></pre>
<p>Here is the HelloFilter and Greeting Filter:</p>
<pre><code>package example.hello;
import javax.servlet.*;
import java.io.IOException;
public class HelloFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
System.out.println("HelloFilter!");
}
@Override
public void destroy() {
}
}
package example.hello;
import javax.servlet.*;
import java.io.IOException;
public class GreetingFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
System.out.println("Greetings from filter!");
}
@Override
public void destroy() {
}
}
</code></pre>
<p>When I start the application and run <code>curl localhost:8080/greeting</code>, Only "Greetings from filter" is received and the <code>HelloFilter</code> is not invoked.</p>
<p>Besides there is no response from <code>Greeting Controller</code>. It seems that the <code>GreetingFilter</code> blocks the procedure.</p>
<p>So how to set the filter chain in Spring boot. Are there any bugs in the code above?</p>

Can't install Azure Functions and Web Jobs extension : <p>I have been trying to install the Azure Functions and Web Jobs extension, however installation fails. Looking through the error log it appears that the piece that isn't working is this:</p>
<pre><code>Install Error : System.InvalidOperationException: Installation of Azure Functions and Web Jobs Tools failed. To install this extension please install at least one of the following components: Microsoft Azure WebJobs Tools
</code></pre>
<p>I think that the problem is that it is looking for itself with the wrong name (Microsoft Azure WebJobs Tools instead of Microsoft Azure Web Jobs Tools). Is there any way to fix this?</p>
