1.SpringIntegrateStruts2Demo项目结构：
2.LoginAction.java源代码：
view plaincopy to clipboardprint?package com.xqh.action;

import com.xqh.service.MyService;
public class LoginAction extends ActionSupport{
//下面是用于封装用户请求参数的两个属性
private String username;
private String password;
//用于封装处理结果的属性
private String tip;
//系统所用的业务逻辑组件
private MyService ms;
//设置注入业务逻辑组件所必需的setter方法
public void setMs(MyService ms)
{
this.ms = ms;
}
//username属性的setter和getter方法
public void setUsername(String username)
{
this.username = username;
}

//password属性所必需的setter和getter方法
public void setPassword(String password)

}
//tip属性的getter和setter方法
public void setTip(String tip)
{

}
public String getTip()
{

}
//处理用户请求的execute方法
public String execute() throws Exception
{
//调用业务逻辑组件的valid方法来
//验证用户输入的用户名和密码是否正确
if (ms.valid(getUsername(), getPassword()))
{
setTip("Spring与Struts2整合成功！");
return SUCCESS;
}
else
{
return ERROR;
}
}
