stomp-websocket | Stomp client for Web browsers and node.js apps | Runtime Evironment library

As you can see, I have a simple default test. For some unknown reason for me, it does not load the application context, if I remove @SpringBootTest annotation everything works, but without it I cannot do bean injection, so I need this annotation.

I was working on a chat for my project using sockJS and STOMP, after various difficulties with installing the 2 libraries I thought I did that (I tried doing that from index.html, npm install and even downloaded 2 min files and put them in the assets folder), after a while I added

I can't get this project compiled, even doing all the necessary configs but unfortunately without success.

I compiled first exchange-core successfully ! Using this command:

I've read all questions about "cannot find symbol" maven error, but I guess they are not appropriate for me.

First of all, I developed an educational project using Eclipse. It's a simple chat and it's accessible on github. It compiles and runs fine, but now I need to compile it with no Eclipse but Maven. I run mvn clean, mvn validate (both successful). Then mvn compile and I get errors:

Sample project available on Github: https://github.com/codependent/rsocket-rating-service

A Spring Boot RSocket server message mapping expects a requestResponse request, returning a simple POJO:

I am following the quick-start guide on Spring websocket with sockJs and Stomp here: https://spring.io/guides/gs/messaging-stomp-websocket/

At this point, my code looks like to one from guide and works as intended. I have a controller class with a method accepting incoming messages and sending them back to all who subscribed on the topic.

What I want to do, is to change the code, so my @MessageMapping annotated method sends response to all subscribers excluding the one who send the message to the controller in the first place (because the sender is also subscribed to the same topic, but i dont want the sender to keep receiving messages it send itself, it is kind of a loop I guess).

I have seen many docs describing how to send a message to a single subscriber, but have not yet seen on describing how to send to all but one - the initial message sender.

Is there any built-in way to do this easily in Spring websocket?

In my Spring-Boot application, js and css files do not work, it says 404 not found.

My html-page includes the following:

I updated my project from Spring Boot 1.5.6.RELEASE to 2.2.5.RELEASE and now I get an error claiming that the web server cannot be started because org.apache.tomcat.util.modeler.Registry.disableRegistry() cannot be found. This is a call made by Spring and it's not under my control. I have as dependencies org.apache.tomcat tomcat-servlet-api and org.apache.tomcat tomcat-catalina version 9.0.33, which are pretty new.

The error message itself seems very verbose but I don't really understand what am I supposed to do. I don't think it's my job to tamper with the class path.

I set up a WebSocket with spring decribed in this tutorial: https://spring.io/guides/gs/messaging-stomp-websocket/. What i need is that my Server send out a message to specific users every 5 seconds. So i first made this:
