@ControllerAdvice未处理异常

Question

我已经浏览了所有相关的帖子，但是我的@Controlller建议似乎没有处理从Controller类抛出的自定义异常。但是@Controller类中的@ExceptionHandler确实处理了异常。我不知道是什么错误。

@控制器建议等级：

package com.test.controller;
import com.test.exception.EmployeeException;

@EnableWebMvc
@ControllerAdvice         
public class EmployeeExceptionController {

@ExceptionHandler(EmployeeException.class)
public ModelAndView employeeNotFound(EmployeeException ex){

    String msg="employee with the "+ex.getId()+" not found";
    ModelAndView mv=new ModelAndView("helloWorld");
    mv.addObject("message",msg);
    mv.addObject("name","boss");
    return mv;
   }

}

@ControllerAdvice与控制器位于同一个包中。

您需要对您的@ControlllerAdvie异常实现“订购”，并使用订购接口的getorder方法返回订单。

顺序越低，优先级越高。这样，您可以首先捕获响应实体异常，并在全局异常处理程序捕获它们之前对其进行处理。
