User表

　　id：

　　username：登陆账号

　　password：登陆密码

　　name：用户名

　　email：用户邮箱

　　telephone：用户电话

　　state(1,0):根据邮箱判断用户是否激活

　　code：

　　image：用户头像

　　level：用户等级

　　coin：金币

(根据用户表单进行创建User表)

　　点击立即注册

　　　　用户成功->登陆界面

　　　　注册失败->用户名存在

　　将表单数据链接数据库

<form action="${pageContext.request.contextPath }/UserAction_register }" method="post">

</form>

　　创建User实体(domain层)

    private String id;

    private String username;

    private String password;

    private String name;

    private String email;

    private String telephone;

    private Integer state;

    private String code;

    private String image;

    private Integer level;

    private Integer coin;
package com.Gary.domain;

public class User {

    private String id;

    private String username;

    private String password;

    private String name;

    private String email;

    private String telephone;

    private Integer state;

    private String code;

    private String image;

    private Integer level;

    private Integer coin;

    public String getId() {

        return id;

    }

    public void setId(String id) {

        this.id = id;

    }

    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 getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getEmail() {

        return email;

    }

    public void setEmail(String email) {

        this.email = email;

    }

    public String getTelephone() {

        return telephone;

    }

    public void setTelephone(String telephone) {

        this.telephone = telephone;

    }

    public Integer getState() {

        return state;

    }

    public void setState(Integer state) {

        this.state = state;

    }

    public String getCode() {

        return code;

    }

    public void setCode(String code) {

        this.code = code;

    }

    public String getImage() {

        return image;

    }

    public void setImage(String image) {

        this.image = image;

    }

    public Integer getLevel() {

        return level;

    }

    public void setLevel(Integer level) {

        this.level = level;

    }

    public Integer getCoin() {

        return coin;

    }

    public void setCoin(Integer coin) {

        this.coin = coin;

    }

}

User.java

　　用户注册流程

　　一开始用户先来到UserAction.java中register()方法

    public String register() throws Exception {

        // TODO Auto-generated method stub

        userService.addUser(user);

        return "toLogin";    

    }

　　通过regiser()方法来到UserService.java

public class UserService {

    private UserDao userDao;

    public void addUser(User user) {

　　　　

        userDao.addUser(user);

    }

}

　　通过addUser()来到Dao层save(user)

public class UserDao extends HibernateDaoSupport{

    public void addUser(User user) {

        // TODO Auto-generated method stub

        //拿到与当前线程绑定的session

        Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();

        session.save(user);

    }

}

　　register.jsp自动封装表单字段

        <form action="${pageContext.request.contextPath }/UserAction_register }" method="post">

            <div class="register-box">

                <label for="username" class="username_label"> 用 户 名 <input maxlength="20" name="username" type="text" placeholder="您的用户名和登录名" />

                <div class="tips"></div>

            </div>

            <div class="register-box">

                <label for="username" class="other_label"> 设 置 密 码 <input maxlength="20" type="password" name="password" placeholder="建议至少使用两种字符组合" />

　　 测试

　　在项目中进行表单注册

表单校验

　　页面自带表单校验

　　通过引入jquery.validate.min.js就可以实现

//input各种判断

    //用户名：

    $('input').eq(0).blur(function(){

        if($(this).val().length==0){

            $(this).parent().next("div").text("");

            $(this).parent().next("div").css("color",'#ccc');

        }else if($(this).val().length>0 && $(this).val().length<4){

            $(this).parent().next("div").text("长度只能在4-20个字符之间");

            $(this).parent().next("div").css("color",'red');

        }else if($(this).val().length>=4&& !isNaN($(this).val())){

            $(this).parent().next("div").text("用户名不能为纯数字");

            $(this).parent().next("div").css("color",'red');

        }

    })

    //密码

    $('input').eq(1).blur(function(){

        if($(this).val().length==0){

            $(this).parent().next("div").text("");

            $(this).parent().next("div").css("color",'#ccc');

        }else if($(this).val().length>0 && $(this).val().length<3){

            $(this).parent().next("div").text("长度只能在3-20个字符之间");

            $(this).parent().next("div").css("color",'red');

        }else{

            $(this).parent().next("div").text("");

        }

    })

//    确认密码

    $('input').eq(2).blur(function(){

        if($(this).val().length==0){

            $(this).parent().next("div").text("");

            $(this).parent().next("div").css("color",'#ccc');

        }else if($(this).val()!=$('input').eq(1).val()){

            $(this).parent().next("div").text("两次密码不匹配");

            $(this).parent().next("div").css("color",'red');

        }else{

            $(this).parent().next("div").text("");

　　书写表单校验提示信息

<div class="register-box">

                <label for="username" class="username_label"> 邮箱 <input maxlength="20" name="email" type="text" placeholder="您的邮箱" />

                </label>

                <div class="tips"><label class="error" for="email" style="display:none">请输入正确的邮箱</label></div>

            </div>

　　让提示信息变得好看

　　错误信息颜色变红

<style>

    .error{

        color:red;

    }

</style>
<div class="register-box">

                <label for="username" class="username_label"> 邮箱 <input maxlength="20" name="email" type="text" placeholder="您的邮箱" />

                </label>

                <div class="tips"><label class="error" for="email" style="display:none; padding-left:0px ; line-height: 25px;color:red">请输入正确的邮箱</label></div>

            </div>

Ajax实现用户名异步校验

　　异步校验：当用户注册账号一离焦，立马将数据与数据库中的数据进行校验

　　给用户名表单添加Ajax校验

<label for="username" class="username_label"> 用 户 名 <input id="username" maxlength="20" name="username" type="text" placeholder="您的用户名和登录名" />

                </label>
$(function()

        {

        $("#username").blur(function(){

            $.post(

            //action地址

            //提交的数据

            {},

            //回调函数

            function(data)

            {

            }

            //数据的格式

            "json"

            )

        })

    })

　　

　　

　　基于Ajax异步校验检测，Web层，Service层，Dao层

　　Web层校验用户名是否存在

public String checkUsername() throws Exception {

        //获得用户username

        boolean success = userService.findUserByUsername(user.getUsername());

        //获得原生Servlet对象

        ServletActionContext.getResponse().getWriter().write("{\"success\":"+success+"}");

        return null;

    }

　　Service层去查找有没有username

public boolean findUserByUsername(String username) {

        // TODO Auto-generated method stub

        Long count = userDao.findUserByUsername(username);

        if(count==0)

            return true;

        else

            return false;

    }

　　Dao层对数据库进程数据查询

public Long findUserByUsername(String username){

        // TODO Auto-generated method stub

        Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();

        String sql = "select count(*) from user where username = ?";

        NativeQuery query = session.createSQLQuery(sql);

        //1号位置设置为username

        query.setParameter(1,username);

        BigInteger result = (BigInteger)query.uniqueResult();

        return result.longValue();

    }

　　register.jsp返回要查询的值

$(function()

        {

        $("#username").blur(function(){

            var usernameInput = $(this).val();

            //alert(usernameInput);

            $.post(

                //action地址checkUsername()

                "${pageContext.request.contextPath}/UserAction_checkUsername",

                //提交的数据

                {"username":usernameInput},

                //回调函数

                function(data)

                {

                    var success = data.success;

                    //可以添加

                    if(success)

                    {

                        $("#usernameInfo").css("color","green");

                        $("#usernameInfo").html("用户名可以使用！");

                    }

                    //不可添加

                    else

                    {

                        $("#usernameInfo").css("color","red");

                        $("#usernameInfo").html("用户名已经被注册！");

                    }

                },

UserAction.java

　　编写用户激活逻辑，设置用户state属性从0变1

MailUtils.sendMail(user.getEmail(), "请激活", "恭喜您注册成功，请点击下面的链接激活！！ <a href='http://localhost:8080/Gary_SSHForum/UserAction_active?userCode="+user.getCode()+"'>点击这里</a>");

　　Web层用户激活

public String active() throws Exception {

        userService.activeUser(userCode);

        return "toLogin";

    }

　　Service层传递数据给Dao层

public void activeUser(String userCode) {

        // TODO Auto-generated method stub

        userDao.activeUser(userCode);

    }

　　Dao层修改数据库中State为1

    public void activeUser(String userCode) {

        Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();

        String sql = "update user set state = 1 where code = ?";

        NativeQuery query = session.createSQLQuery(sql);

        query.setParameter(1,userCode);

        query.executeUpdate();

    }

　　用户注册

　　

　　查看SQL数据库中用户信息

　　阿里云邮箱中激活用户信息

　　点击激活后，修改用户个人state值

项目过程中的问题

一、Struts has detected an unhandled exception:

Messages:
  1. Duplicate entry 'Gary' for key 'username_UNIQUE'
  2. could not execute statement
  3. could not execute statement; SQL [n/a]; constraint [username_UNIQUE]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

　　注册信息重名，不能添加重复的username
