struts2是通过过滤器启动的，以下是web.xml

struts2的action

LoginAction.java

package user.action;import org.apache.struts2.convention.annotation.Action;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.Result;import user.entity.User;import com.opensymphony.xwork2.ActionSupport;@Namespace("/user")//命名空间public class LoginAction extends ActionSupport{	private static final long serialVersionUID = -6962103412798846062L;	private User user1;	private User user2;	@Action(value="login-index",results={@Result(name=SUCCESS,location="login-index.jsp")})	public String loginIndex(){		System.out.println("login-index");		return SUCCESS;	}		@Action(value="login",results={@Result(name=SUCCESS,location="login-success.jsp")})	public String login(){		System.out.println("login");		return SUCCESS;	}	public User getUser1() {		return user1;	}	public void setUser1(User user1) {		this.user1 = user1;	}	public User getUser2() {		return user2;	}	public void setUser2(User user2) {		this.user2 = user2;	}		}

package user.entity;public class User {	private String username;	public String getUsername() {		return username;	}	public void setUsername(String username) {		this.username = username;	}	}

login-index.jsp

<%@ page language="java" pageEncoding="utf-8"%>		  	  
    			 
    
     	 	username1:	 	
     	 	username2:	 	
     	 	
     	 
    
	

login-success.jsp

<%@ page language="java" pageEncoding="utf-8"%>		  	  
    			 user1: ${user1.username }		
	 user2: ${user2.username }		
	

使用tomcat6部署应用，并访问路径http://localhost/项目名称/user/login-index

服务端执行@Action(value="login-index"注解的方法loginIndex()，并返回login-index.jsp

输入表单数据，并提交

表单使用get方式提交，所以这时候浏览器地址栏的路径变为

http://localhost/项目名称/user/login?user1.username=13&user2.username=123

服务端执行@Action(value="login注解的方法login()，并返回login-success.jsp

就这样，一个简单的struts2流程就实现了
