Struts2-2.了解struts.xml>package>action>result的name属性
result决定跳转到哪个视图(jsp),可以预设值有多个。
<?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="itcast" namespace="/test" extends="struts-default"> <action name="helloword" class="cn.itcast.action.HelloWordAction" method="execute"> <result name="success">/WEB-INF/page/hello.jsp</result> <result name="success2">/WEB-INF/page/hello2.jsp</result> </action> <!-- 如果要访问该action,需要在浏览器输入:package的namespace+action的name --> </package> </struts>

package cn.itcast.action; public class HelloWordAction { private String msg; public String getMessage() {return msg;} public String execute(){ msg="Struts应用"; return "success2";//找到对应的action>result的name="success2"的视图地址 } }
对应的视图有
