如何在 Spring MVC 中的 @controllerAdvice 或 @RestControllerAdvice 中找到控制器名称？

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);
        }

    }

1. 我将@ControllerAdvice 与@ExceptionHandler 一起使用。
2. 我需要在handle方法中获取发生异常的控制器类名和包名或类对象

Answer 1

这应该工作

@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);
  }
