@ControllerAdvice 没有处理异常

Question

我已经浏览了所有相关的帖子，但我的@ControllerAdvice 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。我没有知道是什么错误。

web.xml：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
      version="2.5">    
<display-name>Archetype Created Web Application</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

调度程序-servlet.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xsi:schemaLocation="

    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">


<context:component-scan base-package="com.test.controller,com.test.exception"/>
 <mvc:annotation-driven />

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/views/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean> 

@ControllerAdvice 类：

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 与控制器在同一个包中。

您需要为您的@ControllerAdvice 异常实现“Ordered”，并使用 Ordered 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它们被全局异常处理程序捕获之前对其进行处理。
