When IDEA creates a module, square brackets appear after the name

Problem Description

There is such a problem with the name of my module project.
SpringMVC-demo03[springMVC-demo03(1)]
I can’t bear the obsessive-compulsive disorder. I want to be uniform. Change it

Cause Analysis and Solutions

reason

Arifactid and module names are different when creating submodules

Solution

method 1

In Project Structure, change the module name Module Name to be the same as ArtifactId

Method 2

Right-clicking the module->Refactor->Rename to change the directory name to Module name can also solve the problem. This is actually to change the ArtifactId name
to Module name

Method 3

Modify the **.iml file name in the current submodule to achieve the removal effect, because I found that I have 2 .iml files, so I just delete one of the incorrect names.
