如何在 Spring MVC 中的@controllerAdvice 或@RestControllerAdvice 中查找控制器名称？

Question

    @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);
        }

    }

我正在使用@ControllerAdvice 和@ExceptionHandler。
我需要获取发生异常的控制器class名称和包名称或class句柄方法中的对象

Answer 1

这应该有效

@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);
  }
