JQuery+Ajax+Struts2+Hibernate框架整合實現完整登錄注冊的是示例分析，針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
一、開發環境的部署
程序結構：
BootStrap+Ajax+Struts2+Hibernate+MySql
僅供參考：能實現相關功能即可
操作系統：ubuntu 14.10
前端框架：BootStrap 注：此框架只是為了實現用戶界面，和具體功能無關
數據庫：mysql-5.5 數據庫工具：emma
服務器：tomcat 服務器工具：Myeclipse 10（已配置好Struts2和Hibernate環境）
注意：
程序調試過程可能會產生亂碼，只需保持所有工具編碼方式相同即可。
二、項目文件配置
1、新建Web Project，命名為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被我刪了，這點夠用了。
<?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"> <!-- 登錄 --> <action name="login" class="com.action.Login" method="login"></action> <!-- 登出 --> <action name="logout" class="com.action.Logout" method="logout"></action> <!-- 注冊 --> <action name="register" class="com.action.Register" method="register"></action> <!-- 郵件發送 --> <action name="sendmail" class="com.action.SendMail" method="sendmail"></action> </package> </struts>
4、配置/src/hibernate.cfg.xml（hibernate數據庫配置文件），注意倒數第4行有個<mapping />是沒有的需要自己創建，將在下一步配置
<?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路徑、指明數據庫名稱--> <property name="connection.url">jdbc:mysql://localhost:3306/test</property> <!--指明數據庫賬戶和密碼--> <property name="connection.username">root</property> <property name="connection.password">root</property> <!--指明JDBC驅動--> <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下創建com.hibernate包，在該包下創建bookchat.hbm.xml（hibernate對象關系映射文件），并配置
注意<class name="com.hibernate.User" />中的這個User類是自定義的數據庫對象類（pojo），將在下一步配置
<?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類名，指明數據庫表名--> <class name="com.hibernate.User" table="user"> <id column="id" type="int"> <generator class="native" /> </id> <!--指明數據庫字段名、字段類型--> <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包下創建User類
package com.hibernate;
public class User {
private int user_id; //對應數據庫中user_id
private int phone; //手機號
private String email; //郵件
private String username; //用戶名
private String password; //密碼
private String icon; //用戶頭像
private String description; //自定義描述
private int followThreadNum; //關注書單數量
private int followPeopleNum; //關注的人數量
private int fansNum; //粉絲數量
private int haveMsg; //當前是否有新消息
public User() {
super();
}
//這個構造方法在注冊時有用
public User(String email, String username, String password) {
// 用戶內容：username,password,email
// 系統定義：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包下創建CreateTable類，之后Run as - Java Application，查看控制臺是否輸出了sql語句
package com.db;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class CREATTABLEDONOT {
public static void main(String[] args) {
// 默認讀取hibernate.cfg.xml文件
Configuration cfg = new Configuration().configure();
SchemaExport export = new SchemaExport(cfg);
export.create(true, true);
}
}三、檢查數據庫
1、打開數據庫GUI工具，查看test數據庫下是否有一個user表，若能打開user表說明之前配置成功。
2、編輯user表：設置字段默認值，可以向表中添加數據。
四、網頁UI設計
1、我們在struts.xml文件配置中已經埋下伏筆：
<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>
我們可以在網頁中請求/login,/logout,/register來訪問這三個Action處理類，當然這三個類具體的內容我們還沒寫，先放著。
2、現在開始思考網頁設計需要什么東西...
<1> 首頁提供登陸和注冊鏈接
<2> 登陸彈出框和注冊頁面
<3> 登陸/注冊成功，登陸和注冊消失，顯示用戶名和退出登陸
<4> 我們想達到的效果：登陸/注冊成功后顯示用戶名，登陸失敗后動態提示錯誤詳情！
五、JQuery+Ajax設計
1、 主要的JQuery和Ajax代碼
(function(window, $) {
var SOKK = {};
ys.common = SOKK;
//郵箱驗證
SOKK.sendmail = function(){
var email = $("#inputEmail").val().trim();
if(!checkEmail(email)){
return false;
}
//發送請求
$.get("/sendmail","email="+email,function(data){
data = JSON.parse(data);
tip(data.code);
})
}
//注冊
SOKK.signup = function(form){
var form = $(form);
//成功方可繼續執行
if(!checkSignUp(form.find("input")))
return false;
//序列化表單，生成JSON對象
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(); //如何跳轉到首頁？
} else {
tip(data.code);
}
})
};
// 登錄
SOKK.login = function(form) {
var form = $(form);
var input = form.find("input");
var username=$.trim(input[0].value);
var password=$.trim(input[1].value);
if(checkLogin(username,password)){
return false;
}
var dataParam = {};
dataParam.username = username;
dataParam.password = password;
// 這里的dataParam是鍵值對，但服務器獲取的時候是?username=xx&password=xx;
// 如果使用json傳輸那么就不能用這種方式而必須用$.ajax，而且json在服務器端還要再解析，
// 所以在發送請求時，不建議使用json。接受數據可以使用json
$.post("/login", dataParam, function(data) {
// json字符串->json對象
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對象
data = JSON.parse(data);
if (data.code==200){
location.reload();
}
})
};
})(window, $)2、自定義工具代碼
// 自定義提示
function tip(info){
if(isNaN(info)){
toastr.info(info);
}else{
var msg;
if(info<300){
switch(info){
case 100: msg="加入書架成功！"; break;
case 101: msg="關注本書成功！"; break;
case 102: msg="已移動到【正在看】！"; break;
case 103: msg="已移動到【準備看】！"; break;
case 104: msg="已移動到【已看完】！"; break;
case 105: msg="已移動到【回收站】！"; break;
case 110: msg="驗證郵件已發送到你的郵箱！";break;
case 200: msg="請求成功！"; break;
case 202: msg="請求已接受，但尚未處理。"; break;
case 204: msg="請求成功，但無返回內容。"; break;
default : break;
}
toastr.success(msg);
}else if(info<1000){
switch(info){
case 301: msg="請求網頁的位置發生改變！"; break;
case 400: msg="錯誤請求，請輸入正確信息！"; break;
case 401: msg="非法請求，未授權進入此頁面！"; break;
case 403: msg="拒絕請求！"; break;
case 404: msg="請求頁面不存在！"; break;
case 408: msg="請求超時！"; break;
case 500: msg="服務器出錯！"; break;
case 500: msg="服務不可用！"; break;
case 900: msg="用戶名/密碼錯誤，請重新輸入"; break;
case 903: msg="服務器出錯，請重試！"; break;
case 904: msg="服務器無返回信息！"; break;
case 905: msg="網絡出錯！"; break;
case 906: msg="注冊失敗，請重試！";break;
case 907: msg="郵箱驗證碼錯誤！";break;
case 908: msg="用戶名已存在！";break;
case 909: msg="郵箱已被注冊！";break;
case 910: msg="驗證郵件發送失敗！";break;
default : break;
}
toastr.error(msg);
}else{
toastr.info(info);
}
}
}
//注冊檢查
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 = $.trim(input[4].value);
for (var i = 0; i < input.length; i++) {
if(input[i].value.length<=0){
tip("所有內容不得為空！");
return false;
}
};
if(username.length<4){
tip("用戶名不得少于4個字符！");
return false;
}
if(password1!==password2){
tip("兩次輸入的密碼不同！");
return false;
}
if(password1.length<6){
tip("密碼不得少于6個字符！");
return false;
}
return true;
}
function checkLogin(username,password){
if(!username){
tip("請輸入用戶名！");
return false;
}
if(!password){
tip("請輸入密碼！");
return false;
}
}
function checkEmail(email){
var reg = /^([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,3}$/;
if(email){
if(reg.test(email)){
return true;
}else{
tip("郵箱地址不符合規范！");
return false;
}
}else{
tip("郵箱地址不得為空！");
return false;
}
}3、toastr是一個前端非阻塞的提示插件，可以到 http://www.bootcdn.cn/toastr.js/ 下載使用
六、Action設計
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("用戶名：" + username + "--密碼：" + password);
// 登陸返回用戶id
Object obj = hs.login(username, password);
if (obj != null) {
System.out.println("用戶名密碼正確");
request.getSession().setAttribute("username", username);
request.getSession().setAttribute("userid", obj);
System.out.println("用戶名" + username + "的Session設置完畢～");
System.out.println("用戶id的Session設置完畢～");
oj.putCode(200);
} else {
System.out.println("用戶名密碼錯誤");
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");
// 判斷用戶輸入和生成的郵箱驗證碼是否相同
if (!(emailcode.equals(sm.getMailCode()))) {
oj.putCode(907);
oj.send();
return;
}
// 檢測用戶名/郵箱是否唯一
if (!bs.isUnique("User", "username", username)) {
oj.putCode(908);
oj.send();
return;
}
if (!bs.isUnique("User", "email", email)) {
oj.putCode(909);
oj.send();
return;
}
// 構建User對象
User user = new User(email, username, password);
// 建立對象關系映射
Boolean reged = bs.register(user);
if (reged) {
System.out.println("用戶注冊成功");
request.getSession().setAttribute("username", username);
oj.putCode(200);
} else {
System.out.println("注冊失敗");
oj.putCode(906);
}
oj.send();
}
}4、 SendMail.java SMTP協議發送郵件的類，使用前需要導入mail的jar包，同時，還要設置開啟發件人郵箱的smtp服務
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服務器主機名
private static String PASS = "xxxxxxxx"; // SMTP服務器密碼
private static String mailCode; // 郵件驗證碼
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 = "歡迎您使用書聊網！ 立即激活您的賬戶";
String mailContent = "<p>尊敬的用戶：</p><p>你好！立即激活您的賬戶，和書聊網會員一起看書交流。要激活您的賬戶，只需復制下面的驗證碼到注冊頁面確認。 </p>"
+ mailCode + "<p>版權所有© 1999 - 2015 BookChat。保留所有權利。</p>";
// 設置主要信息
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);
// 開啟郵件對象
MimeMessage message = new MimeMessage(session);
// 設置發件人/收件人/主題/發信時間
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());
// 設置消息對象內容
BodyPart mdp = new MimeBodyPart();// 新建一個存放信件內容的BodyPart對象
mdp.setContent(mailContent, "text/html;charset=utf-8");// 給BodyPart對象設置內容和格式/編碼方式
Multipart mm = new MimeMultipart();// 新建一個MimeMultipart對象用來存放BodyPart對象(事實上可以存放多個)
mm.addBodyPart(mdp);// 將BodyPart加入到MimeMultipart對象中(可以加入多個BodyPart)
message.setContent(mm);// 把mm作為消息對象的內容
message.saveChanges();
// 開啟傳輸對象
Transport transport = session.getTransport("smtp");
transport.connect("smtp." + HOST, QQ, PASS); // 這里的115798090也要修改為您的QQ號碼
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("----------返回的數據是：" + json);
try {
PrintWriter out = ServletActionContext.getResponse().getWriter();
out.print(json);
out.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
}七、Hibernate Dao設計
這塊都是一些操作數據庫的內容，大家都有自己的風格，仔細一點寫就好了。代碼太亂，我就不放出來嚇人了-.-! 。
