(转)struts1 也能使用拦截器

我用struts1用习惯了。不想换S2 可是我比较喜欢S2的拦截器。所以就想了下怎么让s1也能拥有拦截器。做的不好别喷我 我第一次写博客！
废话就不多说了，我直接进正题！

1·首先写一个类 MyInterceptor 继承ActionServlet,代码如下

public class MyInterceptor extends ActionServlet {

 @Override
 public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws IOException, ServletException {
  // TODO Auto-generated method stub
  System.out.println("dopost");//这里可以写成自己的拦截代码。。大家就随意发挥吧
  super.doPost(request, response);
 }
 @Override
 public void doGet(HttpServletRequest request, HttpServletResponse response)
   throws IOException, ServletException {
  // TODO Auto-generated method stub
  System.out.println("doget");//这里可以写成自己的拦截代码。。大家就随意发挥吧
  super.doGet(request, response);
 }
}

2·然后把WEB.xml改下下面这样 

  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.MyInterceptor.MyInterceptor</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
