struts2+jquery 实现ajax登陆
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
一、新建一個web項目：test,配置好struts2的環境(詳細配置見：http://www.cnblogs.com/wuweidu/p/3841297.html)
? ? ? 導入Jquery的js文件到項目
二、在com.action包下，新建一個loginAction.java
?
loginAction.java的代碼如下
package com.action;import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.ParentPackage; import org.apache.struts2.convention.annotation.Result; import org.apache.struts2.convention.annotation.Results;import com.opensymphony.xwork2.ActionSupport;@Action("login") @ParentPackage(value = "json-default") @Results({ @Result(name = "success", type = "json", params = { "data", "flag" }), }) public class LoginAction extends ActionSupport {/*** */private static final long serialVersionUID = 1751244794407005783L;private String flag;private String username;private String password;public String execute() {try {if (getUsername() == null || getUsername().trim().equals("")) {setFlag("用戶名不能為空");return SUCCESS;} else if (getPassword() == null || getPassword().trim().equals("")) {setFlag("密碼不能為空");return SUCCESS;} else if (getUsername().trim().equals("admin")&& getPassword().equals("admin")) {setFlag("登陸成功");return SUCCESS;} else {setFlag("用戶名或密碼錯誤");return SUCCESS;}} catch (Exception e) {e.printStackTrace();setFlag("登陸異常");return SUCCESS;}}public String getFlag() {return flag;}public void setFlag(String flag) {this.flag = flag;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}}三、在WebRoot目錄下新建index.jsp和success.jsp
index.jsp登陸界面 ?success.jsp登陸成功后跳轉的界面
index.jsp內容如下
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%String path = request.getContextPath();String basePath = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ path + "/"; %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"><title>My JSP 'index.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <script type="text/javascript" src="./resource/js/jquery.min.js"></script> </head> <script type="text/javascript">$(document).ready(function() {$(".loginButton").click(function() {var name = $("#username").val();//獲取登陸用戶名var password = $("#password").val(); //獲取登陸密碼$.post("login", {username : name,password : password}, callback, "json");});function callback(data) {var value=data.flag;if(value=="登陸成功"){location.href="./success.jsp";}else{alert(value);}}); </script> <body><input name="username" id="username" type="text" /><input name="password" id="password" type="password" /><button class="loginButton" class="btn btn-inverse">登陸</button> </body> </html>
