如何从ControllerAdvice类的ControllerAdvice选择器检索属性

如何从ControllerAdvice类的ControllerAdvice选择器检索属性

这是一个解决方案。
给定

@Target({ElementType.TYPE})@Retention(RetentionPolicy.RUNTIME)public @interface UseAdviceA {  public String myValue();}

控制者

@RestController@UseAdviceA(myValue = "ApiController")@RequestMapping("/myapi")class ApiController { ...}

您的控制器建议应类似于

@ControllerAdvice(annotations = {UseAdviceA.class})class AdviceA {  @ExceptionHandler({SomeException.class})  public ResponseEntity<String> handleSomeException(SomeException pe, HandlerMethod handlerMethod) {    String value = handlerMethod.getMethod().getDeclaringClass().getAnnotation(UseAdviceA.class).myValue();     //value will be ApiController    return new ResponseEntity<>("SomeString", HttpStatus.BAD_REQUEST);  }
