1. What you want to do

--Set exception handling with ExceptionHandler --Know which method of which controller caused the exception

2. Version, conditions, etc.

Java 11
Spring Boot 2.1.1.RELEASE

3. What I did

--Add HandlerMethod handlerMethod to the parameter of the method annotated with ExceptionHandler

`MyExceptionHandler.java`



@ExceptionHandler(MyException.class)
public ResponseEntity<String> myExceptionHandler(
    MyException exception,
    HandlerMethod handlerMethod) {

    //abridgement
}

--See Javadoc for HandlerMethod -- getMethod () and getMethodAnnotation (java.lang.Class <A> annotationType) can be used

4. Document

Spring Docs - 1.3.6. Exceptions > Method Arguments
Javadoc - org.springframework.web.bind.annotation.ExceptionHandler --It was written in Spring Docs. I didn't write it in Javadoc. It doesn't even say Principal.

end.
