我正在为Spring MVC中的异常处理示例演示应用程序.我正在尝试 Exception Handling With @ControllerAdvice

我按照此链接中描述的步骤进行操作.

但是,当我运行我的应用程序时,我得到以下错误

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.test.core.ApplicationException

有关详细信息,请参阅我正在处理的课程

ApplicationException.java

public class ApplicationException extends RuntimeException{


/**
 * 
 */
private static final long serialVersionUID = -9061684361606685158L;
private ErrorStatus errorStatus;
private int msgNumber;
private Object []args;

public ApplicationException(){}

public ApplicationException(ErrorStatus errorStatus, int msgNumber,
        Object[] args) {
    this.errorStatus = errorStatus;
    this.msgNumber = msgNumber;
    this.args = args;
  }
    //getter setters
}

控制器类

ApplicationExceptionController.java

 @Controller
@RequestMapping("/exception")
public class ApplicationExceptionController {

@RequestMapping(value="/error",method=RequestMethod.GET)
@ResponseBody
public void helloException() …

我想在 Spring Rest api 的控制器级别验证实体。这是我的代码：

@RestController
@RequestMapping("/orgs")
public class OrganizationController {
    @PostMapping("/")
    public ResponseEntity<ValidationResponse> addOrganization(@Valid @RequestBody Organization organization){
        //code here
    }

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public ResponseEntity<ValidationResponse> invalidInput(MethodArgumentNotValidException ex) {        
        ValidationResponse response = new ValidationResponse();
        response.setSuccess(false);
        response.setMessage(ex.getMessage());

        return new ResponseEntity<ValidationResponse>(response, HttpStatus.BAD_REQUEST);
    }

}

如果我在控制器类中包含 ExceptionHandler ，它就可以正常工作。但是，如果我将这个异常处理程序移动到 @ControllerAdvice 中，如下所示，它不起作用。

@ControllerAdvice
public class ExceptionHandlingController {

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public ResponseEntity<ValidationResponse> invalidInput(MethodArgumentNotValidException ex) {
        ValidationResponse response = new ValidationResponse();
        response.setSuccess(false);
        response.setMessage(ex.getMessage());
        return new ResponseEntity<ValidationResponse>(response, HttpStatus.BAD_REQUEST);
    }
}

从控制台日志我发现它被扫描了：

ExceptionHandlerExceptionResolver - Detected @ExceptionHandler methods in defaultExceptionHandler
