spring应用实例

新建一个登陆页面：loginActionSupport.jsp，代码如下

<%@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，代码如下：

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，代码示例如下：

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");

}

}
