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;
    }
    
    
    
}

　　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" />
                </label>
                <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" />
                </label>
                <div class="tips"></div>
            </div>
            <div class="register-box">

　　register()中手动封装表单未添加数据

public String register() throws Exception {
        // TODO Auto-generated method stub
        
/*
     自动封装的打1
     private String id;
    private String username;    1
    private String password;    1
    private String name;    1
    private String email;    1
    private String telephone;    1
    private Integer state;
    private String code;
    private String image;
    private Integer level;
    private Integer coin;        
 */
        
        //没有的数据手动封装
        user.setState(0);
        user.setCode(UUID.randomUUID().toString());
        user.setImage("0");
        user.setLevel(1);
        user.setCoin(1000);
        
        //是否添加成功
        userService.addUser(user);
    
        return "toLogin";    
        
    }

配置hibernate

　　 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("");
        }

实现From表单中邮箱校验

　　邮箱name="email"

 <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"></div>
            </div>

<script type="text/javascript">

    $(function(){
        $("#myform").validate({
            
            //json格式规则
            rules:{
                "email":{
                    //是否未必填字段
                    "required":true,

                }
            },
            
            //如果违反了规则应该怎么办
            messages:{

register.jsp

　　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
                    {

    }

　　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) {

 　　对用户登陆进行测试

　　此时数据库中纯在两条数据

　　

　　测试失败：用户名不存在，用户密码登陆错误，用户未激活

　　测试成功：跳转index页面

　　添加一个提示用户去激活邮箱的界面

项目过程中的问题

一、Struts has detected an unhandled exception:

Messages:

Duplicate entry 'Gary' for key 'username_UNIQUE' could not execute statement 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
