spring springmvc mybatis 整合

最近鼓捣ssm框架的东西，写篇博文记录。
环境 apache-tomcat-8.0.33、jdk1.8.0_05 maven Dynamic Web Module 2.5
1、各个xml配置文件的配置
(1)pom.xml 配置清单文件
连接池用的阿里巴巴Druid，数据库mysql，指定jdk编译版本1.8

2、工程结构
(1)分层结构

(2)实体类

package cn.web.open.model;

import java.util.Date;

public class User {
    private String userCode;
    private String userName;
    private String userPwd;
    private String email;
    private String address;
    private Date userBorn;

    public String getUserCode() {
        return userCode;
    }
    public void setUserCode(String userCode) {
        this.userCode = userCode;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getUserPwd() {
        return userPwd;
    }
    public void setUserPwd(String userPwd) {
        this.userPwd = userPwd;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public Date getUserBorn() {
        return userBorn;
    }
    public void setUserBorn(Date userBorn) {
        this.userBorn = userBorn;
    }

}

dao接口

package cn.web.open.dao;
import cn.web.open.model.User;

public interface UserDao {
    User findById(String code,String pwd);
}

service接口

package cn.web.open.service;
import cn.web.open.model.User;

public interface UserService {

    User findById(String code,String pwd);
}

service实现类,@Resource注入dao

package cn.web.open.service.impl;

import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import cn.web.open.dao.UserDao;
import cn.web.open.model.User;
import cn.web.open.service.UserService;

@Service("userService")
public class UserServiceImpl implements UserService{
    @Resource
    private UserDao userDao;

    public User findById(String code,String pwd) {
        User user = userDao.findById(code,pwd);
        return user;
    }

}

控制器controller

package cn.web.open.controller;


import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.web.open.model.User;
import cn.web.open.service.UserService;

@Controller
//@RequestMapping("/user")
public class UserController {

    @Resource
    private UserService userService;

    @RequestMapping("/login")
    public String login(HttpServletRequest request, Model model) {
        String code = request.getParameter("usercode");
        String pwd = request.getParameter("password");
        User user_login = userService.findById(code,pwd);
        System.out.println("--->"+user_login);

        if (null == user_login) {
            System.out.println("Error login!");
            return "redirect:index.jsp?oper=error";
        } else {
            model.addAttribute("user", user_login);
            return "pages/success";
        }
    }
}

sql语句文件mappers/userMapper.xml

<pre name="code" class="html"><pre name="code" class="html"><?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="cn.web.open.dao.UserDao">
    <resultMap type="User" id="UserResult">
        <result column="USER_CODE" property="userCode" />
        <result column="USER_NAME" property="userName" />
        <result column="USER_PWD" property="userPwd" />
    </resultMap>
    <!-- 查询条件:账号密码用户类型. 0第一个参数,1第二个参数,对应dao接口参数 -->
    <select id="findById" parameterType="String" resultMap="UserResult">
        SELECT USER_CODE,USER_NAME,USER_PWD FROM BLOG_USER WHERE USER_CODE=#{0} AND USER_PWD=#{1} AND USER_TYPE=2
    </select>

    <!-- <select id="getAllUsers" resultMap="userResult"> SELECT USER_CODE,USER_NAME,USER_PWD,CREATE_DATE FROM BLOG_USER </select> -->
</mapper>

(3)前台的一些测试页面

WEB_INF下文件不能通过URL直接访问,登录页面网上拿了别人做了一个页面，挺有趣的，访问工程地质,端口你自己配的,输入管理员类型的账号测试

刚开始对于各种注解的使用不甚了解鼓捣了许久,用maven管理项目构建时也碰到许多小问题，着实查了许多资料,下过别人的demo参考，总算是把ssm这一套搭起来了，如果发现有问题，请留言指教。demo下载http://download.csdn.net/detail/u012809062/9486330
