HttpServletResponse .sendError returns empty response body when missing CSRF token

I have CSRF enabled in the config, and when I try to make a POST request to an authenticated endpoint without a CSRF token in header or cookie (the very first request), Spring returns an error response with status code but no response body (header CONTENT-LENGTH is 0). I have this problem in one of my projects, but I tried to reproduce the behavior with a simpler setup.
HelloController.java
#RestController
public class HelloController {
#PostMapping("/hello/")
public String hello() {
return "Hello World";
}
}
SecurityConfig.java
#EnableWebSecurity
#RequiredArgsConstructor
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private final CustomAccessDeniedHandler customAccessDeniedHandler;
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().authenticated();
http.exceptionHandling().accessDeniedHandler(customAccessDeniedHandler);
}
}
CustomAccessDeniedHandler.java
#Component
#Slf4j
public class CustomAccessDeniedHandler implements AccessDeniedHandler {
#Override public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException) throws IOException, ServletException {
String errorMessage = accessDeniedException.getMessage();
log.error("Access Denied - {}", errorMessage);
response.sendError(HttpStatus.FORBIDDEN.value(), errorMessage);
}
}
I'm aware that with this setup, CSRF is enabled by default.
I also customized the AccessDeniedHandler because I want Spring to spit out more specific error message when it's working as intended.
When I use curl -i -X POST http://localhost:8080/hello/, Spring returns HTTP/1.1 403 with empty response. However, if I remove the line http.authorizeRequests().anyRequest().authenticated(); in SecurityConfig and start the same request above, there's an error message like normal behavior.
{
"timestamp":"2021-07-10T23:06:28.172+00:00",
"status":403,
"error":"Forbidden",
"message":"Could not verify the provided CSRF token because your session was not found.",
"path":"/hello/"
}
I have searched for similar questions but no one has answered why response.sendError() doesn't work when .anyRequest().authenticated() is present with the condition of missing CSRF token. The workaround seems to be using response.setStatus() and response.getWriter().write() to build the error message from scratch. Is it an expected behavior or am I missing something?

Have a look at the log you've given:
o.s.s.w.a.i.FilterSecurityInterceptor : Failed to authorize filter invocation [POST /error] with attributes [authenticated]
The .anyRequest().authenticated() is blocking the access to the default /error page. If you configure in such a way that it permits this specific path, it can process as you expected.
You can do this by simply adding this:
.antMatchers("/error").permitAll()
In fact, you can allow all the urls you want if you declare a list of urls you want to allow and set that to the antMatchers parameter.

TransactionException is never called from Spring JPA when I close my database - Why?

I'm trying to close my database connection, just to find out what type of exception is being called.
I have my entity here that I want to save.
try {
dataService.save(dataLogg);
}catch(TransactionException e1) {
System.out.println("hello Sending message!");
mailService.sendMessage(alarm, email, "Database connection is refused. Make sure that database is reestablish, or else, you cannot login. Logging shutting down.", message);
break; // This will jump out of the while loop
}catch(JDBCConnectionException e2) {
System.out.println("hello JDBC!");
}catch(Exception e3) {
System.out.println("hello!" + e3.getCause());
saveDataLater.add(dataLogg); // Save it for later if something just happen
}
But the error I got is TransactionException and it being called from: catch(Exception e3) and not catch(TransactionException e1).
Why is this happening?

SpringBoot - Application returns 404 Not Found when started in debug mode

I am experiencing a weird situation where I am not able to get the spring boot application working in Debug mode. The same application responds correctly when started in normal mode. This behaviour is only observed when I am adding this external library as dependency in my build.gradle file.
I am very sure the issue is because of the addition of this said library and sure how I should resolve this.
My IDE is IntelliJ
What I have tried so far:
Clean and rebuild
IntelliJ invalidate caches and restart
Gradle entry
compile "com.mpatric:mp3agic:0.9.1"
I can see the application starts correctly from the logs and listening on port 8080. When I make the API call there is no entry in the logs.
UPDATE
When I run my application in with debug level logging resolution, I get the following:

So basically the request is reaching the server. The response is getting created but it's not being sent by the server.

Spring Boot APP deploy to external tomcat

Basically,I want to use spring boot auto configure the datasource related function,and hope to package spring boot app to a war,and deploy to tomcat.
github URL:https://github.com/oneslideicywater/CustomlizeOfKaKaHair
After running an MVN build, I skip the test, I deploy the .war to TomCat, restart it and...
...everything is well when I run my application in STS IDE. But what the hell happens?
I don't have javax.el on my classpath.

What can I do to solve this problem?

Problem Fixed
Solution:
if findding any "EL" error if your tomcat log,you got upgrade your tomcat to v8+,because so far 2018/5/15 spring boot startio use "el-api-3.00" which is indroduced since tomcat 8+!God,it is version collision again.

Try to disable your database autoconfig as is described in this another Stackoverflow thread:
Disable database autoconfig

Spring Reactive MongoDB connected to MongoDB cloud

I downloaded the example from Spring Data MongoDB 2.0 - Reactive examples.
I'm failing to understand how to make it work.
I set up a cluster in cloud.mongodb.com and they supply me with:
If I am using driver 3.6 or later:
mongodb+srv://stavalfi:<PASSWORD>#cluster0-9yjy8.mongodb.net/test
Else, if I am using driver 3.4 or earlier:
mongodb://stavalfi:<PASSWORD>#cluster0-shard-00-00-
9yjy8.mongodb.net:27017,cluster0-shard-00-01-
9yjy8.mongodb.net:27017,cluster0-shard-00-02-
9yjy8.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-
0&authSource=admin
I don't know what is the version of the driver which spring uses so I chose the first one:
#SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
#EnableReactiveMongoRepositories
#AutoConfigureAfter(EmbeddedMongoAutoConfiguration.class)
#RequiredArgsConstructor
class ApplicationConfiguration extends AbstractReactiveMongoConfiguration {
private final Environment environment;
public static void main(String args[]) throws InterruptedException {
ConfigurableApplicationContext run = SpringApplication.run(ApplicationConfiguration.class);
run.getBean(ReactiveMongoTemplate.class)
.save("something to push")
.subscribe(System.out::println, Throwable::printStackTrace, () -> System.out.println("success"));
Thread.sleep(1000000);
}
#Bean
public LoggingEventListener mongoEventListener() {
return new LoggingEventListener();
}
#Override
#Bean
#DependsOn("embeddedMongoServer")
public MongoClient reactiveMongoClient() {
return MongoClients.create(String.format("mongodb+srv://stavalfi:<MyAccountPassword!>#cluster0-9yjy8.mongodb.net/test"));
// int port = environment.getProperty("local.mongo.port", Integer.class);
// return MongoClients.create(String.format("mongodb://localhost:%d", port));
}
#Override
protected String getDatabaseName() {
return "reactive";
}
}
I'm sure I'm not doing anything as Spring Data MongoDB project expected me to do.
The Exception I get while creating the Bean: MongoClient
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'reactiveMongoClient' defined in example.springdata.mongodb.people.ApplicationConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.mongodb.reactivestreams.client.MongoClient]: Factory method 'reactiveMongoClient' threw exception; nested exception is java.lang.UnsupportedOperationException: No SSL support in java.nio.channels.AsynchronousSocketChannel.

How can I fix this?

Played around with this some. You can find details from Mongo Java Driver tutorials.
First I tried using the DSL approach, which would be neat to have all the setup as code:
application.yml
mongo:
user: training_mongo
password: <my_password>
hosts:
- training-abcde.mongodb.net
database: training
MongoProperties.java
#ConfigurationProperties("mongo")
#Component
public class MongoProperties {
private String user;
private String password;
private List<String> hosts;
private String database;
ApplicationConfiguration.java
#Configuration
#EnableWebFlux
#EnableReactiveMongoRepositories
public class ApplicationConfig extends AbstractReactiveMongoConfiguration {
[...]
#Override
public MongoClient reactiveMongoClient() {
return create(MongoClientSettings.builder()
.clusterSettings(ClusterSettings.builder()
.hosts(mongoProperties.getHosts()
.stream()
.map(ServerAddress::new)
.collect(toList()))
.build())
.streamFactoryFactory(NettyStreamFactory::new)
.sslSettings(SslSettings.builder()
.enabled(true)
.build())
.credential(MongoCredential.createCredential(
mongoProperties.getUser(),
mongoProperties.getDatabase(),
mongoProperties.getPassword().toCharArray()))
.build());
}
#Override
protected String getDatabaseName() {
return DB_NAME;
}
This however crashes, because Netty fires a DNS lookup through the Java stack and that fails:

But doing things less elegantly via the connection URL seem to work:

private String getMongoConnectionUrl() {

return connectionUrl;

I think it haven't SSL Certificate or may be the wrong or dummy SSL Certificate are there. That's why it's display No SSL support in java.nio.channels.AsynchronousSocketChannel

From the docs:
If you are using the reactive driver, Netty is required for SSL. The auto-configuration configures this factory automatically if Netty is available and the factory to use hasn’t been customized already.
Make sure that you have netty on the classpath (either selected modules or netty-all).
