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

 更新时间:2015年10月21日 14:53:16   投稿:mrr   我要评论
最近没有项目做,闲着没事,看到一个书城的网站很好,于是就是仿了一个,把里面的ui直接拿过来用,前端后端自己写的,目前大部分的功能已经实现了。

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

金沙国际官网:mysql-5.5 金沙国际官网工具: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金沙国际官网配置文件),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、指明金沙国际官网名称-->
  <property name="connection.url">jdbc:mysql://localhost:3306/test</property>
  <!--指明金沙国际官网账户和密码-->
  <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类是自定义的金沙国际官网对象类(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,指明金沙国际官网表名-->
 <class name="com.hibernate.User" table="user">
  <id column="id" type="int">
   <generator class="native" />
  </id>
  <!--指明金沙国际官网字段名、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; //对应金沙国际官网中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、检查金沙国际官网

1、打开金沙国际官网GUI工具,查看test金沙国际官网下是否有一个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

这块都是一些操作金沙国际官网的内容,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...
