Eclipse Maven compiles the project

We know that when you write a project with eclipse, you can use Debug for hot deployment, that is, you can automatically compile the Java file without restarting it, but when you save the file, Eclipse is compiled again, and does not erase the unused memory, as if it were a new belt, so If you save a few more times, it will cause a memory overflow.

Another way to compile is to use MAVEN to compile: This will also be able to change the Java files can be compiled in a timely manner, the increased memory is only to recompile the files you changed,

Specific methods:

Select Debug Configurations

Goals: Input Tomcat:run

Base directory Select Browse Workspace Select Current Project

And then:

And then apply debug on the line.
