项目结构目录：注意xml文件放在resources下面

1.1 导入mybatis相关的依赖
pom.xml中添加依赖

<!-- 导入mybatis相关的依赖 -->
<!--druid连接池-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.9</version>
</dependency>
<!-- mysql -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!-- SpringBoot的Mybatis启动器 -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>

1.2 配置application.properties
位置：src/main/resources目录下

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

mybatis.type-aliases-package=com.maximus.domain
mybatis.mapper-locations=classpath:mapper/*.xml

1.3 在数据库中创建user表，sql语句如下所示：

CREATE TABLE `user` (
`id` int(11) NOT NULL auto_increment COMMENT '序号id',
`name` varchar(20) ,
`password` varchar(50) ,
PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

并在表中添加一条记录以供测试使用：

1.4 编写User实体

package com.maximus.domain;
/**
* @Auther:
* @Date:
* @Description:
*/

public class User {
private Integer id;
private String name;
private String password;

public Integer getId() {
return id;
}

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

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}
}

1.5 编写UserMapper接口

package com.maximus.mapper;

import com.maximus.domain.User;

/**
* @Auther:
* @Date:
* @Description:
*/
public interface UserMapper {

public User  findByName(String name);
}

1.6 编写UserMapper.xml映射文件

<?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">
<!-- 该文件存放CRUD的sql语句 -->
<mapper namespace="com.maximus.mapper.UserMapper">

<select id="findByName" parameterType="string" resultType="user">
SELECT 	id,
NAME,
PASSWORD
FROM
user where name = #{value}
</select>
</mapper>

1.7 编写业务接口和实现

package com.maximus.service;

import com.maximus.domain.User;

/**
* @Auther:
* @Date:
* @Description:
*/
public interface UserService {
public User findByName(String name);
}

package com.maximus.service.impl;

import com.maximus.domain.User;
import com.maximus.mapper.UserMapper;
import com.maximus.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
* @Auther:
* @Date:
* @Description:
*/
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;

@Override
public User findByName(String name) {
return userMapper.findByName(name);
}
}

1.8 添加@MapperScan注解

package com.maximus;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
* @Auther:
* @Date:
* @Description:
*/
@SpringBootApplication
@MapperScan("com.maximus.mapper")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

运行启动类：点击用户添加，輸入用户名：eric 密码：123456如下所示

点击登陆：跳转到testTHymeleaf界面，表示整合成功
