struts2使用

1、struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
          "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<!--配置struts2的默认拦截后缀，使只有以*.action结尾的才被struts2处理  -->
	<constant name="struts.action.extension" value="action" /> 
</struts>

2、在web.xml中配置struts2

<!-- 配置struts2 -->
<filter>
    <filter-name>Struts2</filter-name>
    <filter-class>
         org.apache.struts2.dispatcher.FilterDispatcher
    </filter-class>
</filter>
<filter-mapping>
<filter-name>Struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
