看了一些教程，费了不少功夫，这种框架只能照着一个来，但按照某些文章的描述是成功不了的，这就很蛋疼，自己写一篇，备忘和分享。

 

更新！

更新文章 提供githubDemo

框架环境准备

Jdk1.8

Idea 2017.1

maven 3.3.9

 

建立工程

1.新建一个maven webapp project

这个填写自己的工程名字就可以

设置工程的目录属性

工程目录下，建立各种需要的文件。

配置POM

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"

配置Spring-mvc，使注解可用，扫描Bean

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <!-- 扫描web相关的bean -->
    <context:component-scan base-package="com.mt.controller"/>

    <!-- 开启SpringMVC注解模式 -->
    <mvc:annotation-driven/>

    <!-- 静态资源默认servlet配置 -->
    <mvc:default-servlet-handler/>

    <!-- 配置jsp 显示ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

配置spring-mybatis和jdbc

spring-mybatis.xml

mybatis映射文件

UserDao.xml

<?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">

<!-- 设置为IUserDao接口方法提供sql语句配置 -->

    <select id="selectUser" resultType="User" parameterType="long">

    </select>

    <!--返回的是插入的新的记录的id-->
    <insert id="insert" parameterType="com.model.User">
        <!--

        <selectKey keyProperty="id" order="AFTER" resultType="INTEGER">
            SELECT LAST_INSERT_ID()
        </selectKey>
        insert into user (email, password, username,
        role, status, regTime,regIp)
        values (#{email,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR}, #{username,jdbcType=VARCHAR},

    </insert>

</mapper>

 

java实现类

 

User

package com.model;

/**

 */

import java.util.Date;

public class User {

    private long id;
    private String email;
    private String password;
    private String username;
    private String role;
    private int status;
    private Date regTime;
    private String regIp;

    public User(String email, String password, String username, String role, int status, Date regTime, String regIp) {
        this.email = email;
        this.password = password;
        this.username = username;
        this.role = role;
        this.status = status;
        this.regTime = regTime;
        this.regIp = regIp;
    }

    public long getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;

        this.password = password;
    }

    public String getUsername() {

    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public Date getRegTime() {
        return regTime;
    }

    public void setRegTime(Date regTime) {
        this.regTime = regTime;
    }

    public String getRegIp() {
        return regIp;
    }

    public void setRegIp(String regIp) {
        this.regIp = regIp;
    }

}

 

IUserDao

 

package com.mt.dao;

/**
 * Created by city on 2018/3/9.
 */

import com.mt.model.User;

public interface IUserDao {

    User selectUser(long id);

    int insert(User user);

}

IUserService

package com.mt.service;

import com.mt.model.User;

/**
 * Created by city on 2018/3/9.ØØØ
 */

public interface IUserService {

    User selectUser(long userId);

    int insert(User user);

}

UserServiceImpl

package com.mt.service.impl;

/**
 * Created by city on 2018/3/9.
 */

import com.mt.dao.IUserDao;
import com.mt.model.User;
import com.mt.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service("userService")
public class UserServiceImpl implements IUserService {

    @Resource
    private IUserDao userDao;

    public User selectUser(long userId) {
        return this.userDao.selectUser(userId);
    }

    public int insert(User user) {
        return this.userDao.insert(user);
    }

}

单元测试 IUserDaoTest

 

package com.mt.daoTest;

/**

import com.mt.dao.IUserDao;
import com.mt.model.User;

import org.junit.Assert;

public class IUserDaoTest {
    private static final Logger log = LoggerFactory.getLogger(IUserDaoTest.class);

    @Autowired
    protected IUserDao dao;

    @Test
    public void testSelectUser() throws Exception {
        long id = 2;
        User user = dao.selectUser(id);
        System.out.println(user.getUsername());
    }

    @Test
    public void testInsert() throws Exception {
        Date date = new Date(System.currentTimeMillis());
        User user2 = new User("2@mt.com","123","2","manager",1, Date.valueOf("2018-03-08"),"112.112.112.112");
        User user3 = new User("3@mt.com","123","3","manager",0, date,"112.112.112.113");

        int insertResult2 = dao.insert(user2);
        int insertResult3 = dao.insert(user3);

        log.debug("insert user2 result is :{} and insert user3 result is :{} \n",insertResult2,insertResult3);
        System.out.println("insert user2 result is :"+insertResult2+"\n"+"insert user3 result is :"+insertResult3);
        Assert.assertTrue(insertResult2==1);
    }

}
