Struts2配置文件复用代码【web.xml、struts.xml、常量配置】

web.xml的分发器代码：

<!-- 引入struts核心过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

struts.xml代码：

<?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>
<package name="hello" extends="struts-default">
    <action name="hello" class="action.HelloAction" method="execute">
        <result name="success">/index.jsp</result>
    </action>
</package>
</struts>
