2、创建用户模板-用户注册基础

1、创建数据库

 create database crm; 
 use crm;
/*
SQLyog v10.2 
MySQL - 5.1.72-community : Database - crm_hibernate
*********************************************************************
*/


/*!40101 SET NAMES utf8 */;

/*!40101 SET SQL_MODE=''*/;

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
/*Table structure for table `sys_user` */

CREATE TABLE `sys_user` (
  `user_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '用户id',
  `user_code` varchar(32) NOT NULL COMMENT '用户账号',
  `user_name` varchar(64) NOT NULL COMMENT '用户名称',
  `user_password` varchar(32) NOT NULL COMMENT '用户密码',
  `user_state` char(1) NOT NULL COMMENT '1:正常,0:暂停',
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

/*Data for the table `sys_user` */

LOCK TABLES `sys_user` WRITE;

insert  into `sys_user`(`user_id`,`user_code`,`user_name`,`user_password`,`user_state`) values (5,'m0003','小军','123','1'),(6,'m0001','小红','123','1'),(7,'m0001','小明','123','1'),(8,'m0001','小红','123','1');

UNLOCK TABLES;

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

2、创建用户实体/crm/src/com/louis/domain/User.java

package com.louis.domain;

public class User {
    // 主键
    private Long user_id;
    // 登录名称
    private String user_code;
    // 用户姓名
    private String user_name;
    // 密码（保存的时候，需要加密处理）
    private String user_password;
    // 用户的状态 1正常 0暂停
    private String user_state;

    public Long getUser_id() {
        return user_id;
    }

    public void setUser_id(Long user_id) {
        this.user_id = user_id;
    }

    public String getUser_code() {
        return user_code;
    }

    public void setUser_code(String user_code) {
        this.user_code = user_code;
    }

    public String getUser_name() {
        return user_name;
    }

    public void setUser_name(String user_name) {
        this.user_name = user_name;
    }

    public String getUser_password() {
        return user_password;
    }

    public void setUser_password(String user_password) {
        this.user_password = user_password;
    }

    public String getUser_state() {
        return user_state;
    }

    public void setUser_state(String user_state) {
        this.user_state = user_state;
    }
}

3、编写hibernate映射文件/crm/src/com/louis/domain/User.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    
<hibernate-mapping>
    <class name="com.louis.domain.User" table="sys_user">
        <id name="user_id" column="user_id">
            <generator class="native"/>
        </id>
        
        <property name="user_code" column="user_code"/>
        <property name="user_name" column="user_name"/>
        <property name="user_password" column="user_password"/>
        <property name="user_state" column="user_state"/>
    </class>
    
</hibernate-mapping>    

4、引入映射文件/crm/src/applicationContext.xml

    <!-- 引入映射的配置文件 -->
        <property name="mappingResources">
            <list>
                <value>com/louis/domain/User.hbm.xml</value>
            </list>
        </property> 

5、创建用户Action/crm/src/com/louis/web/action/UserAction.java

package com.louis.web.action;

import com.louis.domain.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends ActionSupport implements ModelDriven<User> {

    private static final long serialVersionUID = -3413092622818913571L;
    
    private User user = new User();
    
    public User getModel() {
        return user;
    }

}

6、配置用户模块/crm/src/applicationContext.xml

    <!-- 配置用户的模块 -->
    <bean id="userAction" class="com.louis.web.action.UserAction" scope="prototype">
        
    </bean>

7、配置用户请求/crm/src/struts.xml

<!-- 配置用户的模块 -->
        <action name="user_*" class="userAction" method="{1}">
            <result name="loginOK" type="redirect">/index.jsp</result>
        </action>

8、创建服务类/crm/src/com/louis/service/impl/UserServiceImpl.java

package com.louis.service.impl;

import org.springframework.transaction.annotation.Transactional;

import com.louis.service.UserService;
@Transactional
public class UserServiceImpl implements UserService {

}

9、配置服务类/crm/src/applicationContext.xml

    <bean id="userService" class="com.louis.service.UserServiceImpl">
        
    </bean>

10、action类添加依赖注入/crm/src/com/louis/service/impl/UserServiceImpl.java

    private UserService userService;
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

11、配置依赖注入/crm/src/applicationContext.xml

<!-- 配置用户的模块 -->
    <bean id="userAction" class="com.louis.web.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"/>
    </bean>

12、创建dao/crm/src/com/louis/dao/impl/UserDaoImpl.java

package com.louis.dao.impl;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.louis.dao.UserDao;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

}

13配置dao/crm/src/applicationContext.xml

    <bean id="userDao" class="com.louis.dao.UserDaoImpl">
        
    </bean>

14、service注入dao

    <bean id="userService" class="com.louis.service.UserServiceImpl">
        <property name="userDao" ref="userDao"/>
    </bean>

private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

15、配置dao的属性

    <bean id="userDao" class="com.louis.dao.UserDaoImpl">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

至此，基本的项目建好了

16、创建注册页面regist.jsp

// 验证登录名
    function checkCode(){
        // 获取用户输入的登录名
        var code = $("#user_code").val();
        // 进行判断，说明没有输入登录名
        if(code.trim() == ""){
            // 给提示
            $("#codeId").addClass("error");
            $("#codeId").html("登录名不能为空");
        }else{
            // 登录名不为空，ajax请求，验证
            var url = "${pageContext.request.contextPath}/user_checkCode.action";
            var param = {"user_code":code};
            $.post(url,param,function(data){
                // 操作data，进行判断后台返回的是字符串，可以直接判断
                if(data && data == "no"){
                    // 提示
                    $("#codeId").addClass("error");
                    $("#codeId").html("登录名已经存在");
                }else{
                    $("#codeId").removeClass("error");
                    $("#codeId").html("可以注册");
                }
            });
        }
    }
    
    // 可以阻止表单的提交
    function checkForm(){
        // 先让校验名称的方法先执行以下
        checkCode();
        // 获取error的数量，如果数量 > 0，说明存在错误，不能提交表单
        if($(".error").size() > 0){
            return false;
        }
    }
    

17、/crm/src/com/louis/web/action/UserAction.java

    /**
     * 通过登录名，判断，登录名是否已经存在
     * @return
     */
    public String checkCode(){
        // 调用业务层，查询
        User u = userService.checkCode(user.getUser_code());
        // 获取response对象
        HttpServletResponse response = ServletActionContext.getResponse();
        response.setContentType("text/html;charset=UTF-8");
        try {
            // 获取输出流
            PrintWriter writer = response.getWriter();
            // 进行判断
            if(u != null){
                // 说明：登录名查询到用户了，说明登录已经存在了，不能注册
                writer.print("no");
            }else{
                // 说明，不存在登录名，可以注册
                writer.print("yes");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        
        return NONE;
    }
    

 18、/crm/src/com/louis/service/UserServiceImpl.java

/**
     * 通过登录名进行验证
     */
    public User checkCode(String user_code) {
        return userDao.checkCode(user_code);
    }

19、/crm/src/com/louis/dao/UserDaoImpl.java

/**
     * 通过登录名进行验证
     */
    public User checkCode(String user_code) {
        List<User> list = (List<User>) this.getHibernateTemplate().find("from User where user_code = ?", user_code);
        if (list != null && list.size() > 0) {
            return list.get(0);
        }
        return null;
    }
