spring应用实例

新建一个登陆页面：loginActionSupport.jsp，代码例如以下

 





<%@page contentType="text/html;charset=GBK" isELIgnored="false"%>

 

<html>

 

<head><title>；实现用户登录实例，struts和Spring整合</title></head>

 

<body>





spring

<font size=’22’> $<br> </font> 

<form name="form1" action="/myLogin/loginActionSupportdo" method="post">

 

用户名：<input type="text" name="username" value="${user.username}"/><br>

 

密码：<input type="password" name="password" value="${user.password}"/><br>

 

<input type="submit" name=”method” value="提交"/>

 

</form>

 

</body>

 

</html>

 

创建一个存储登陆用户信息的类：User.java该类继承于ActionForm，代码例如以下：

 





package com.zhaosoft.bean;

 

import org.apache.struts.action.ActionForm;

 

public class User extends ActionForm{

 

private String username=null;

 

private String password=null;

 

public String getUsername() {

 

return username;

 

}

 

public void setUsername(String username) {

 

this.username = username;

 

}

 

public String getPassword() {

 

return password;





spring

} 

public void setPassword(String password) {

 

this.password = password;

 

}

 

}

 

Com.zhaosoft.action中新建一个LoginActionSupport.java，该类不继承于struts的Action，而是继承于Spring的ActionSupport，代码示比例如以下：

 





package com.zhaosoft.action;

 

import javax.servlet.http.HttpServletRequest;

 

import javax.servlet.http.HttpServletResponse;

 

import org.apache.struts.action.ActionForm;

 

import org.apache.struts.action.ActionForward;

 

import org.apache.struts.action.ActionMapping;

 

import org.springframework.context.ApplicationContext;

 

import org.springframework.web.struts.ActionSupport;

 

import com.zhaosoft.bean.User;





spring

import com.zhaosoft.domain.Login; 

public class LoginActionSupport extends ActionSupport {

 

public ActionForward execute(ActionMapping mapping,ActionFormform,

 

HttpServletRequest request,HttpServletResponse response)

 

throws Exception {

 

// 通过ApplicationContext获取配置文件

 

ApplicationContext ctx = getWebApplicationContext();

 

Login login = (Login) ctx.getBean("login");

 

login.login((User) form);





spring

request.setAttribute("msg",login.getMsg()); 

request.setAttribute("user",(User) form);

 

return mapping.findForward("login");

 

}

 

}
