How to debug java in maven plugin with angular2 in Dokcer

Hello every body, I am struggling 3 days but still not find a way to solve it. I hope I can get some help here:
I have a project with 2 maven plugin.

one Plugin is in java.
Another Plugin is angular2.
Over these 2 maven plugins is docker.
In docker container, tomee and mysql runs. I want to debug java with the front-end which means by hitting http://localhost:8080/mywebapp , the system should stop at the break point I set in backend (java file). I am using IntelliJ.

Does somebody know how to do it?

for detail docker settings pls. refer: http://stackoverflow.com/questions/42707998/how-to-debug-java-in-maven-plug-with-angular-2-tomee-in-docker/42717803#42717803
