Compatibility issues with SpringBoot+MyBatis+Jpa+WebSocket - Codes Helper

1. I used Jap, and then Mybatis in my project.
I have a very strange problem here.
is when writing unit tests for mybatis

I found a lot of reasons for the

error on the Internet, but it didn"t solve my problem in the end.
* * finally I found that I just had to comment out the @ Bean of websocketconfig in my project and the problem was solved.
I hope the test is ready to be tested. I"m confused. I think there should be a conflict! But I still don"t know how to be compatible with this problem.

the following is the configuration information related to my project:
