Abnormal reason:

There are two asm packages

Solution:

Delete one of the asm packages

Abnormal reason:

After the subsystem is generated, the content of the startup class CosonleApplication.java in the admin console module is not commented out. The tomcat runtime will start the main method of the startup class running the admin console module instead of the main method of the startup class of the subsystem module, so the controller in the subsystem cannot be found

Solution:

Comment out the startup class CosonleApplication.java in the admin console module
