How to acknowledge a websocket message?

In server side ,how to receive a ACK ?

Issue while running the bootRun

Hi Almar,
Appreciate your real world approach with spring websocket, was trying to run the app but was getting the following error while gradle bootRun.

FAILURE: Build failed with an exception.

• Where:
  Build file '/home/srikanth/chatapp/spring-websocket-chat/build.gradle' line: 3

• What went wrong:
  A problem occurred evaluating root project 'spring-websocket-chat'.

  org.gradle.api.tasks.TaskContainer.create(Ljava/lang/String;Ljava/lang/Class;)Lorg/gradle/api/Task;

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Spring Boot actuators

First of all I have to say really code repository. It has nice demos and displays the functionality of Spring Websocket over STOMP quite well.

I really liked the Actuator endpoints that are in this repository. Have you considered in contributing them to the Spring Boot project, extracting them as a separate module so people can use them?

New endpoint for register is redirected to login

I am making implementing user registration in this project. Now if a make a new endpoint which makes a post request for user, the response returns template of login.html when making post request using postman.

How to show login errors in index.html

I have a question related to trapping and showing server error messages in index.html.

If for example we change method "authenticate" in class WebSecurityConfig as follows:

UsernamePasswordAuthenticationToken token = (UsernamePasswordAuthenticationToken) authentication; if("aaa".equals(token.getCredentials())) throw new AuthenticationException("'aaa' bad password") {};

When logging on using password 'aaa' the user is not logged on, index.html is presented but no error message is displayed.

Is this possible to extend the example to show such errors?

Not Found - org.springframework.boot:spring-boot-starter-tomcat:2.0.0.M2

:compileJava FAILED

FAILURE: Build failed with an exception.

• What went wrong:
  Could not resolve all files for configuration ':compileClasspath'.

Could not find spring-boot-starter-tomcat.jar (org.springframework.boot:spring-boot-starter-tomcat:2.0.0.M2).
Searched in the following locations:
http://repo.spring.io/libs-release/org/springframework/boot/spring-boot-starter-tomcat/2.0.0.M2/spring-boot-starter-tomcat-2.0.0.M2.jar

Unable to add multiple controllers

I can't add multiple controllers. On adding more controller, only ChatController is working

How to save data/messages in database like mysql, maria, postgre or mongo db

I've forked the repository and found it awesome, but I can not find the way to save data to database like mysql, maria, postgre or mongo db. I've not found any resource online as well, So requesting you please add/tell support for persisting data/messages in database like mysql, maria, postgre or mongo db.

SimpMessageHeaderAccessor#getUser is now nullable. How to handle?

I couldn't find a better place to open this... Please redirect me if there is.

spring-messaging, since v5.0.0, has marked method SimpMessageHeaderAccessor#getUser as @Nullable.
Which actually causes Findbugs to fail with code similar to your example, and rightfully so.

Specifically here: PresenceEventListener#handleSessionConnected

String username = headers.getUser().getName();

My question is how is this supposed to be handled properly? (i.e. when #getUser returns null)
Should the code throw an exception? do nothing?
And what does it actually mean that the user is null in this context?

Principal principal = headers.getUser();
if (principal == null) {
    // what should happen here ?
}

Thanks !

unsubscribing from "/app/chat.participants" with stomp broker

I enabled the stomp broker (RabbitMQ), uncommenting this, but now I get the following error while trying to unsubscribe from /app/chat.participants:

<<< ERROR
message:No subscription found
content-type:text/plain
version:1.0,1.1,1.2
content-length:92

UNSUBSCRIBE must refer to an existing subscription.
Subscription to "id='sub-2'" not found.

If I am correct, this is an error generated by RabbitMQ. So I guess that the UNSUBSCRIBE message is forwarded to the stomp broker, but since @SubscribeMapping does not create any subscription in the broker, I get the error.

Is some additional configuration required? Or is it a bug in the framework?
