更改src/struts2.xml的代码:
<?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"> <action name="*_*" method="{2}" class="action.{1}Action"> <result>/result.jsp</result> <result name="add">/{2}.jsp</result> <result name="update">/{2}.jsp</result> </action> </package> </struts>
{1},{2}表示*的顺序,{1}是"_"前面的*,{2}是"_“后面的*.
HelloWorldAction.java的add和update方法也要修改返回值:
public class HelloWorldAction extends ActionSupport{ public String add(){ return "add"; } public String update(){ return "update"; } @Override public String execute() throws Exception{ // TODO Auto-generated method stub System.out.println("执行Action"); return "success"; } }
启动tomcat,然后就可以访问
http://localhost:8080/struts2Test2/HelloWorld.action或者http://localhost:8080/struts2Test2/HelloWorld_.action
http://localhost:8080/struts2Test2/HelloWorld_add.action
http://localhost:8080/struts2Test2/HelloWorld_update.action
