# 一. 回顾 #

前面[拦截器简介][Link 1]讲述了如何实现拦截器。今天讲解配置拦截器的两种方式

# 二. 例子 #

MyFirstInterceptor.java

package com.atguigu.springmvc.interceptor;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.springframework.stereotype.Component;
    import org.springframework.web.servlet.ModelAndView;
    import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
    
    //@Component
    public class MyFirstInterceptor extends HandlerInterceptorAdapter{ 
     
    	@Override
    	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
    			ModelAndView modelAndView) throws Exception { 
    		// TODO Auto-generated method stub
    		super.postHandle(request, response, handler, modelAndView);
    	}
    
    }

springmvc.xml

<mvc:interceptors>
           
            <bean class="com.atguigu.springmvc.interceptor.MyFirstInterceptor"></bean>
            
            
            
            
          
      </mvc:interceptors>
