How to find controller name in @controllerAdvice o

问题:

    @ControllerAdvice
    public class GlobalExceptionHandler {

        @ExceptionHandler(NoHandlerFoundException.class)
        public ResponseEntity<Error> handle(NoHandlerFoundException ex){
            String message = "HTTP " + ex.getHttpMethod() + " for " + ex.getRequestURL() + " is not supported.";
            Error error = new Error(HttpStatus.NOT_FOUND.value(), message);
            return new ResponseEntity<Error>(error, HttpStatus.NOT_FOUND);
        }

    }

1. I am using @ControllerAdvice with @ExceptionHandler.
2. I need to get the exception occurred controller class name and package name or class object inside the handle method

回答1:

This should work

@ControllerAdvice
class AdviceA {

  @ExceptionHandler({SomeException.class})
  public ResponseEntity<String> handleSomeException(SomeException pe, HandlerMethod handlerMethod) {
    Class controllerClass = handlerMethod.getMethod().getDeclaringClass();
    //controllerClass.toString will give you fully qualified name
    return new ResponseEntity<>("SomeString", HttpStatus.BAD_REQUEST);
  }
