基本概念

　　mybatis

　　　　MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。

　　spring

　　　　 Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。

　　spring mvc

　　　　Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。

　　步骤七：编写dao层

package com.ssm.dao;

import com.ssm.entity.Smbms_User;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

@Repository
public interface Smbms_UserMapper {

    public Smbms_User login(@Param("user_code") String user_code, @Param("user_password") String user_password);

}

View Code

　　步骤八：编写dao.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.ssm.dao.Smbms_UserMapper" >

  <select id="login" resultType="Smbms_User">
    select * from smbms_user where userCode=#{user_code} and userPassword=#{user_password}
  </select>

</mapper>

　　步骤九：编写service业务接口层

package com.ssm.service;

import com.ssm.entity.Smbms_User;
import org.apache.ibatis.annotations.Param;

public interface Smbms_UserService {
    public Smbms_User login(String user_code,String user_password);
}

View Code

　　步骤十：编写serviceImpl业务实现层

package com.ssm.service.impl;

import com.ssm.dao.Smbms_UserMapper;
import com.ssm.entity.Smbms_User;
import com.ssm.service.Smbms_UserService;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Isolation;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;

@Service("smbms_UserService")
public class Smbms_UserServcieImpl implements Smbms_UserService {
    //植入Dao层对象
    @Resource
    private Smbms_UserMapper smbms_userMapper;

    //事务
   /* @Transactional(isolation=Isolation.DEFAULT)*/
    @Override
    public Smbms_User login(String user_code, String user_password) {
        return smbms_userMapper.login(user_code,user_password);
    }
}

View Code

　　步骤十一：编写控制器

package com.ssm.controller;

import com.ssm.entity.Smbms_User;
import com.ssm.service.Smbms_UserService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import javax.servlet.http.HttpSession;

@Controller
@RequestMapping("/user")
public class Smbms_UserController {
    //植入Service层分对象
    @Resource
    private Smbms_UserService smbms_userService;

    @RequestMapping("/login")
    public String doLogin(Smbms_User smbms_user, HttpSession session){
        Smbms_User user = smbms_userService.login(smbms_user.getUsercode(), smbms_user.getUserpassword());
        if(user!=null){
            session.setAttribute("user",user);
            return "welcome";
        }
        return "login";
    }

}

<html>
<head>
    <title>登陆</title>
</head>
<body>
    <div>
        <form action="/user/login" method="post">
            用户名：<input type="text" name="usercode"/>
            密码：<input type="password" name="userpassword"/>
            <input type="submit" value="登陆"/>
        </form>
    </div>
</body>
</html>
