JQuery+Ajax+Struts2+Hibernate框架整合实现完整的登录注册

最近在仿造一个书城的网站： http://www.yousuu.com ,UI直接拿来用，前端后端自己写，目前大部分功能已经实现，

就把具体的 登录注册功能 拿来分享一下。PS：又写登录注册会不会被人喷啊=。=

一、开发环境的部署

程序结构：

BootStrap+Ajax+Struts2+Hibernate+MySql

仅供参考：能实现相关功能即可

操作系统：ubuntu 14.10

前端框架：BootStrap   注：此框架只是为了实现用户界面，和具体功能无关

数据库：mysql-5.5 数据库工具：emma

服务器：tomcat 服务器工具：Myeclipse 10（已配置好Struts2和Hibernate环境）

注意：

程序调试过程可能会产生乱码，只需保持所有工具编码方式相同即可。

二、项目文件配置

1、新建Web Project，命名为ROOT

2、配置/WebRoot/WEB-INF/web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>ROOT</display-name> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <error-page> <error-code>404</error-code> <location>/error.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/error.jsp</location> </error-page> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>

3 、 配置/src/struts.xml（struts配置文件），其他的action和interceptor被我删了，这点够用了。

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="default" namespace="/" extends="struts-default"> <!-- 登录 --> <action name="login" class="com.action.Login" method="login"></action> <!-- 登出 --> <action name="logout" class="com.action.Logout" method="logout"></action> <!-- 注册 --> <action name="register" class="com.action.Register" method="register"></action> <!-- 邮件发送 --> <action name="sendmail" class="com.action.SendMail" method="sendmail"></action> </package> </struts>

4、配置/src/hibernate.cfg.xml（hibernate数据库配置文件），注意倒数第4行有个<mapping />是没有的需要自己创建，将在下一步配置

<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="myeclipse.connection.profile">Myeclipse Mysql</property> <!--指明JDBC路径、指明数据库名称--> <property name="connection.url">jdbc:mysql://localhost:3306/test</property> <!--指明数据库账户和密码--> <property name="connection.username">root</property> <property name="connection.password">root</property> <!--指明JDBC驱动--> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <!--指明mysql方言--> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="hibernate.current_session_context_class">thread</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">true</property> <property name="format_sql">true</property> <mapping resource="com/hibernate/bookchat.hbm.xml" /> </session-factory> </hibernate-configuration>

5、/src下创建com.hibernate包，在该包下创建bookchat.hbm.xml（hibernate对象关系映射文件），并配置

注意<class name="com.hibernate.User" />中的这个User类是自定义的数据库对象类（pojo），将在下一步配置

<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <!--指明Bean类名，指明数据库表名--> <class name="com.hibernate.User" table="user"> <id column="id" type="int"> <generator class="native" /> </id> <!--指明数据库字段名、字段类型--> <property name="user_id" column="user_id" type="int" /> <property name="phone" column="phone" type="int" /> <property name="email" column="email" type="string" /> <property name="username" column="username" type="string" /> <property name="password" column="password" type="string" /> <property name="icon" column="icon" type="string" /> <property name="description" column="description" type="string" /> <property name="followThreadNum" column="followThreadNum" type="int" /> <property name="followPeopleNum" column="followPeopleNum" type="int" /> <property name="fansNum" column="fansNum" type="int" /> <property name="haveMsg" column="haveMsg" type="int" /> </class> </hibernate-mapping>

6、/src下的com.hibernate包下创建User类

package com.hibernate; public class User { private int user_id; //对应数据库中user_id private int phone; //手机号 private String email; //邮件 private String username; //用户名 private String password; //密码 private String icon; //用户头像 private String description; //自定义描述 private int followThreadNum; //关注书单数量 private int followPeopleNum; //关注的人数量 private int fansNum; //粉丝数量 private int haveMsg; //当前是否有新消息 public User() { super(); } //这个构造方法在注册时有用 public User(String email, String username, String password) { // 用户内容：username,password,email // 系统定义：user_id,icon,followThreadNum,followPeopleNum,fansNum,haveMsg // 留空:phone,description, this.user_id = 39212; // this.phone = phone; this.email = email; this.username = username; this.password = password; this.icon = "images/icon.png"; // this.description = description; this.followThreadNum = 0; this.followPeopleNum = 0; this.fansNum = 0; this.haveMsg = 0; } public int getUser_id() { return user_id; } public void setUser_id(int user_id) { this.user_id = user_id; } public int getPhone() { return phone; } public void setPhone(int phone) { this.phone = phone; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getIcon() { return icon; } public void setIcon(String icon) { this.icon = icon; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public int getFollowThreadNum() { return followThreadNum; } public void setFollowThreadNum(int followThreadNum) { this.followThreadNum = followThreadNum; } public int getFollowPeopleNum() { return followPeopleNum; } public void setFollowPeopleNum(int followPeopleNum) { this.followPeopleNum = followPeopleNum; } public int getFansNum() { return fansNum; } public void setFansNum(int fansNum) { this.fansNum = fansNum; } public int getHaveMsg() { return haveMsg; } public void setHaveMsg(int haveMsg) { this.haveMsg = haveMsg; } }

7、/src下的com.db包下创建CreateTable类，之后Run as - Java Application，查看控制台是否输出了sql语句

package com.db; import org.hibernate.cfg.Configuration; import org.hibernate.tool.hbm2ddl.SchemaExport; public class CREATTABLEDONOT { public static void main(String[] args) { // 默认读取hibernate.cfg.xml文件 Configuration cfg = new Configuration().configure(); SchemaExport export = new SchemaExport(cfg); export.create(true, true); } }

三、检查数据库

1、打开数据库GUI工具，查看test数据库下是否有一个user表，若能打开user表说明之前配置成功。

2、编辑user表：设置字段默认值，可以向表中添加数据。

四、网页UI设计

1、我们在struts.xml文件配置中已经埋下伏笔：

<action name="login" class="com.action.Login" method="login"></action>
<action name="logout" class="com.action.Logout" method="logout"></action>
<action name="register" class="com.action.Register" method="register"></action>
<action name="sendmail" class="com.action.SendMail" method="sendmail"></action>

我们可以在网页中请求/login,/logout,/register来访问这三个Action处理类，当然这三个类具体的内容我们还没写，先放着。

2、现在开始思考网页设计需要什么东西...

<1> 首页提供登陆和注册链接

<2> 登陆弹出框和注册页面

<3> 登陆/注册成功，登陆和注册消失，显示用户名和退出登陆

<4> 我们想达到的效果：登陆/注册成功后显示用户名，登陆失败后动态提示错误详情！

五、JQuery+Ajax设计

1、 主要的JQuery和Ajax代码

(function(window, $) { var SOKK = {}; ys.common = SOKK; //邮箱验证 SOKK.sendmail = function(){ var email = $("#inputEmail").val().trim(); if(!checkEmail(email)){ return false; } //发送请求 $.get("/sendmail","email="+email,function(data){ data = JSON.parse(data); tip(data.code); }) } //注册 SOKK.signup = function(form){ var form = $(form); //成功方可继续执行 if(!checkSignUp(form.find("input"))) return false; //序列化表单，生成JSON对象 var JStr =form.serialize(); // var JStr = JSON.stringify(JForm); tip(JStr); $.post("/register",JStr,function(data){ data = JSON.parse(data); if (data.code == 200) { location.reload(); //如何跳转到首页？ } else { tip(data.code); } }) }; // 登录 SOKK.login = function(form) { var form = $(form); var input = form.find("input"); var username=$.trim(input[0].value); var password=$.trim(input[1].value); if(checkLogin(username,password)){ return false; } var dataParam = {}; dataParam.username = username; dataParam.password = password; // 这里的dataParam是键值对，但服务器获取的时候是?username=xx&password=xx; // 如果使用json传输那么就不能用这种方式而必须用$.ajax，而且json在服务器端还要再解析， // 所以在发送请求时，不建议使用json。接受数据可以使用json $.post("/login", dataParam, function(data) { // json字符串->json对象 data = JSON.parse(data); if (data.code == 200) { location.reload(); } else { tip(data.code); } }) }; //登出 SOKK.logout = function(){ $.get("/logout", function (data) { //json字符串->json对象 data = JSON.parse(data); if (data.code==200){ location.reload(); } }) }; })(window, $)

2、自定义工具代码

// 自定义提示 function tip(info){ if(isNaN(info)){ toastr.info(info); }else{ var msg; if(info<300){ switch(info){ case 100: msg="加入书架成功！"; break; case 101: msg="关注本书成功！"; break; case 102: msg="已移动到【正在看】！"; break; case 103: msg="已移动到【准备看】！"; break; case 104: msg="已移动到【已看完】！"; break; case 105: msg="已移动到【回收站】！"; break; case 110: msg="验证邮件已发送到你的邮箱！";break; case 200: msg="请求成功！"; break; case 202: msg="请求已接受，但尚未处理。"; break; case 204: msg="请求成功，但无返回内容。"; break; default : break; } toastr.success(msg); }else if(info<1000){ switch(info){ case 301: msg="请求网页的位置发生改变！"; break; case 400: msg="错误请求，请输入正确信息！"; break; case 401: msg="非法请求，未授权进入此页面！"; break; case 403: msg="拒绝请求！"; break; case 404: msg="请求页面不存在！"; break; case 408: msg="请求超时！"; break; case 500: msg="服务器出错！"; break; case 500: msg="服务不可用！"; break; case 900: msg="用户名/密码错误，请重新输入"; break; case 903: msg="服务器出错，请重试！"; break; case 904: msg="服务器无返回信息！"; break; case 905: msg="网络出错！"; break; case 906: msg="注册失败，请重试！";break; case 907: msg="邮箱验证码错误！";break; case 908: msg="用户名已存在！";break; case 909: msg="邮箱已被注册！";break; case 910: msg="验证邮件发送失败！";break; default : break; } toastr.error(msg); }else{ toastr.info(info); } } } //注册检查 function checkSignUp(input){ var username = $.trim(input[0].value); var password1 = $.trim(input[1].value); var password2 = $.trim(input[2].value); var email = $.trim(input[3].value); var emailcode = $.trim(input[4].value); for (var i = 0; i < input.length; i++) { if(input[i].value.length<=0){ tip("所有内容不得为空！"); return false; } }; if(username.length<4){ tip("用户名不得少于4个字符！"); return false; } if(password1!==password2){ tip("两次输入的密码不同！"); return false; } if(password1.length<6){ tip("密码不得少于6个字符！"); return false; } return true; } function checkLogin(username,password){ if(!username){ tip("请输入用户名！"); return false; } if(!password){ tip("请输入密码！"); return false; } } function checkEmail(email){ var reg = /^([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,3}$/; if(email){ if(reg.test(email)){ return true; }else{ tip("邮箱地址不符合规范！"); return false; } }else{ tip("邮箱地址不得为空！"); return false; } }

3、toastr是一个前端非阻塞的提示插件，可以到 http://www.bootcdn.cn/toastr.js/ 下载使用

六、Action设计

1、Login.java

package com.action; import javax.servlet.http.HttpServletRequest; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import com.service.BaseService; import com.service.BaseServiceImpl; import com.util.OperateJSON; public class Login extends ActionSupport { private static final long serialVersionUID = 4679952956618457478L; private String username; private String password; public void login() { HttpServletRequest request = ServletActionContext.getRequest(); BaseService hs = new BaseServiceImpl(); OperateJSON oj = new OperateJSON(); username = request.getParameter("username"); password = request.getParameter("password"); System.out.println("用户名：" + username + "--密码：" + password); // 登陆返回用户id Object obj = hs.login(username, password); if (obj != null) { System.out.println("用户名密码正确"); request.getSession().setAttribute("username", username); request.getSession().setAttribute("userid", obj); System.out.println("用户名" + username + "的Session设置完毕～"); System.out.println("用户id的Session设置完毕～"); oj.putCode(200); } else { System.out.println("用户名密码错误"); oj.putCode(900); } oj.send(); } }

2、Logout.java

package com.action; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import com.util.OperateJSON; public class Logout extends ActionSupport { private static final long serialVersionUID = -6758897982192371466L; HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); OperateJSON oj = new OperateJSON(); public void logout() { request.getSession().removeAttribute("username"); request.getSession().invalidate(); if (request.getSession().getAttribute("username") == null) { oj.putCode(200); } else { oj.putCode(903); } oj.send(); } }

3、Register.java

package com.action; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext; import com.hibernate.User; import com.opensymphony.xwork2.ActionSupport; import com.service.BaseService; import com.service.BaseServiceImpl; import com.util.OperateJSON; public class Register extends ActionSupport { private static final long serialVersionUID = -3356620731966076779L; HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); BaseService bs = new BaseServiceImpl(); OperateJSON oj = new OperateJSON(); SendMail sm = new SendMail(); public void register() { String username = request.getParameter("username"); String password1 = request.getParameter("password1"); String password2 = request.getParameter("password2"); String password = (password1.equals(password2) ? password1 : null); String email = request.getParameter("email"); String emailcode = request.getParameter("emailcode"); // 判断用户输入和生成的邮箱验证码是否相同 if (!(emailcode.equals(sm.getMailCode()))) { oj.putCode(907); oj.send(); return; } // 检测用户名/邮箱是否唯一 if (!bs.isUnique("User", "username", username)) { oj.putCode(908); oj.send(); return; } if (!bs.isUnique("User", "email", email)) { oj.putCode(909); oj.send(); return; } // 构建User对象 User user = new User(email, username, password); // 建立对象关系映射 Boolean reged = bs.register(user); if (reged) { System.out.println("用户注册成功"); request.getSession().setAttribute("username", username); oj.putCode(200); } else { System.out.println("注册失败"); oj.putCode(906); } oj.send(); } }

4、 SendMail.java  SMTP协议发送邮件的类，使用前需要导入mail的jar包，同时，还要设置开启发件人邮箱的smtp服务

package com.action; import java.util.Date; import java.util.Properties; import javax.mail.BodyPart; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Multipart; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; import javax.servlet.http.HttpServletRequest; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import com.util.OperateJSON; public class SendMail extends ActionSupport { private static final long serialVersionUID = -4724909293302616101L; private static String QQ = "392102018"; // qq private static String HOST = "qq.com"; // SMTP服务器主机名 private static String PASS = "xxxxxxxx"; // SMTP服务器密码 private static String mailCode; // 邮件验证码 OperateJSON oj = new OperateJSON(); public void sendmail() { HttpServletRequest request = ServletActionContext.getRequest(); String email = request.getParameter("email"); System.out.println(email); String mailCode = SendMail.setMailCode(); try { beginSend(email, mailCode); oj.putCode(110); } catch (MessagingException e) { oj.putCode(910); } finally { oj.send(); } } public static String setMailCode() { mailCode = 100000 + (int) (Math.random() * 900000) + "BC"; System.out.println(mailCode); return mailCode; } public String getMailCode() { return SendMail.mailCode; } public void beginSend(String email, String mailCode) throws MessagingException { String mailTo = email; // 收件方mail地址 String mailTitle = "欢迎您使用书聊网！ 立即激活您的账户"; String mailContent = "<p>尊敬的用户：</p><p>你好！立即激活您的账户，和书聊网会员一起看书交流。要激活您的账户，只需复制下面的验证码到注册页面确认。 </p>" + mailCode + "<p>版权所有© 1999 - 2015 BookChat。保留所有权利。</p>"; // 设置主要信息 Properties props = new Properties(); props.put("mail.smtp.host", "smtp." + HOST); props.put("mail.smtp.auth", "true"); Session session = Session.getInstance(props); session.setDebug(true); // 开启邮件对象 MimeMessage message = new MimeMessage(session); // 设置发件人/收件人/主题/发信时间 InternetAddress from = new InternetAddress(QQ + "@" + HOST); message.setFrom(from); InternetAddress to = new InternetAddress(mailTo); message.setRecipient(Message.RecipientType.TO, to); message.setSubject(mailTitle); message.setSentDate(new Date()); // 设置消息对象内容 BodyPart mdp = new MimeBodyPart();// 新建一个存放信件内容的BodyPart对象 mdp.setContent(mailContent, "text/html;charset=utf-8");// 给BodyPart对象设置内容和格式/编码方式 Multipart mm = new MimeMultipart();// 新建一个MimeMultipart对象用来存放BodyPart对象(事实上可以存放多个) mm.addBodyPart(mdp);// 将BodyPart加入到MimeMultipart对象中(可以加入多个BodyPart) message.setContent(mm);// 把mm作为消息对象的内容 message.saveChanges(); // 开启传输对象 Transport transport = session.getTransport("smtp"); transport.connect("smtp." + HOST, QQ, PASS); // 这里的115798090也要修改为您的QQ号码 transport.sendMessage(message, message.getAllRecipients()); transport.close(); } }

5、OpreateJSON

package com.util; import java.io.IOException; import java.io.PrintWriter; import org.apache.struts2.ServletActionContext; import net.sf.json.JSONObject; public class OperateJSON { JSONObject json; public OperateJSON() { json = new JSONObject(); json.put("code", ""); json.put("msg", ""); json.put("data", ""); } public OperateJSON(String str) { json = JSONObject.fromObject(str); } public void put(String key, Object value) { json.remove(key); json.put(key, value); } public void putCode(Object value) { json.remove("code"); this.put("code", value); } public void putMsg(Object value) { json.remove("msg"); this.put("msg", value); } public void remove(String key) { json.remove(key); } public void send() { System.out.println("----------返回的数据是：" + json); try { PrintWriter out = ServletActionContext.getResponse().getWriter(); out.print(json); out.flush(); } catch (IOException e) { e.printStackTrace(); } } }

七、Hibernate Dao设计

这块都是一些操作数据库的内容，大家都有自己的风格，仔细一点写就好了。代码太乱，我就不放出来吓人了-.-! 。

八、总结

开始想展示下结果的还是算了，也就那么回事。一个小例子，瑕疵难免，还望大神们指正。

写完了，心情好多了，招聘会去看看也好，找不找工作不重要，重要的是我走在正确的路上，只有依靠自己才是强者...
