springMVC中多个拦截器Interceptor的执行顺序

1.springMVC中拦截器实现这个接口implements HandlerInterceptor

第一个拦截器：

public class MyInterceptor1 implements HandlerInterceptor{ public void afterCompletion(HttpServletRequest arg0,   HttpServletResponse arg1, Object arg2, Exception arg3)   throws Exception {  System.out.println("=======> my interceptor1 :afterCompletion() "); } public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,   Object arg2, ModelAndView arg3) throws Exception {  // TODO Auto-generated method stub  System.out.println("=======> my interceptor1:postHandle() "); } public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1,   Object arg2) throws Exception {  System.out.println("=======> my interceptor1:preHandle() ");  return true; }}

第二个拦截器

public class MyInterceptor2 implements HandlerInterceptor{public void afterCompletion(HttpServletRequest arg0,HttpServletResponse arg1, Object arg2, Exception arg3)throws Exception {System.out.println("=======> my interceptor2:afterCompletion() ");}public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,Object arg2, ModelAndView arg3) throws Exception {// TODO Auto-generated method stubSystem.out.println("=======> my interceptor2:postHandle() ");}public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1,Object arg2) throws Exception {System.out.println("=======> my interceptor2:preHandle()");return true;}

2.在springmvc的配置文件中

<mvc:interceptors><mvc:interceptor><mvc:mapping path="/**"/><bean class="com.lifeng.interceptor.MyInterceptor1" /></mvc:interceptor><mvc:interceptor><mvc:mapping path="/**"/><bean class="com.lifeng.interceptor.MyInterceptor2" /></mvc:interceptor></mvc:interceptors>

3.执行顺序：

=======> my interceptor1:preHandle() 
 =======> my interceptor2:preHandle()
 .......
 =======> my interceptor2:postHandle() 
 =======> my interceptor1:postHandle() 
 =======> my interceptor2:afterCompletion() 
 =======> my interceptor1 :afterCompletion()
