package fzl.user.struts.demo;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {public String list(){System.out.println("list");return "success";}public String input(){System.out.println("input");return "success";}public String add(){System.out.println("add");return "success";}}

Run Tomcat and enter http: // localhost: 9000/strustdemo1/input in the browser.
Similarly, input the response directory to get the corresponding page output.

package fzl.user.struts.demo;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {public String list(){System.out.println("list");return "list";}public String input(){System.out.println("input");return "input";}public String add(){System.out.println("add");return "add";}}
<action name="User" class="fzl.struts.demo.UserAction"> <result name="add">/WEB-INF/User/list.jsp</result> <result name="input">/WEB-INF/User/input.jsp</result> <result name="list">/WEB-INF/User/add.jsp</result> </action>
Enter http: // localhost: 9000/strutsdemo2/user! Add to get the corresponding page

package fzl.user.struts.demo;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {public String list(){System.out.println("list");return "success";}public String input(){System.out.println("input");return "success";}public String add(){System.out.println("add");return "success";}}If you are not familiar with the wildcard configuration
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><struts><package name="default" namespace="/" extends="struts-default"> <action name="*_*" class="fzl.user.struts.demo.{1}Action"method="{2}"><result>/WEB-INF/{1}/{2}.jsp</result></action> </package></struts>
