   > @dfsmallsky do you have your own class loader in the application or what frameworks (like MyBatis, PageHelper, from your stack traces)? If you're using Spring Boot, it should be easy to create a reproduce project, I did encounter this problem because of class loader issue, if you're willing to help, maybe we can try to solve it, I need a minimal yet runnable reproduce application, can you create one in the GitHub @dfsmallsky
   
   Finally I resolve this!The problem is there is a mysql-connector-java.jar in my java ext path,I don't know how and why it is there...So when try to enhance mysql class, the classloader is extClassloader and can not find InstanceMethodsAroundInterceptor.
   Delete the jar in ext path,the mysql trace work!
