常量配置

包配置（package----多个action、多个拦截器、多个拦截器引用的集合）

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts> 	
    	<package name="default" extends="struts-default" namespace="/"> 		... 	</package> </struts>

命名空间的配置

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts> 	 	<package name="com" extends="struts-default" namespace="/">
    		<action name="login" class="com.LoginAction">
    			<result name="success">success.jsp</result>
    			<result name="error">error.jsp</result>
    		</action>
    	</package> 	<package name="phn" extends="struts-default" namespace="/phn">
    		<action name="register" class="phn.RegisterAction">
    			<result name="success">success.jsp</result>
    			<result name="error">error.jsp</result>
    		</action>
    	</package>
    </struts>

拦截器（AOP（面向切面编程）的思想）配置

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts>
    	<constant name="struts.i18n.encoding" value="utf-8"></constant>
    	<package name="default" extends="struts-default" namespace="/">
    		<interceptors>
    			
    			<interceptor name="loginPermissions" class="com.phn.LoginPermissions"></interceptor>
    			
    			<interceptor name="log" class="com.phn.LoginInterceptor"></interceptor>
    			
    			<interceptor-stack name="permissionsAndLog">
    				<interceptor-ref name="loginPermissions"></interceptor-ref>
    				<interceptor-ref name="log"></interceptor-ref>
    			</interceptor-stack>
    		</interceptors>
    		<action name="login" class="com.LoginAction">
    			<interceptor-ref name="permissionsAndLog"></interceptor-ref>
    			<result name="success">success.jsp</result>
    		</action>
    	</package>
    </struts>
