1、查看不同MyBatis版本整合Spring时使用的适配包；
http://www.mybatis.org/spring/
2、下载整合适配包
https://github.com/mybatis/spring/releases
• 3、官方整合示例，jpetstore
https://github.com/mybatis/jpetstore-6

1.
①.导入需要的Spring的jar包
②.导入MyBatis的包
以及与数据库驱动包
③.最后导入MyBatis与Spring整合的适配包
2.写各个部分的配置文件
①、MyBatis的配置文件 JavaEE——Mybatis（12）--MyBatis与Spring整合--MyBatis相关配置文件
②、Spring的配置文件 管理所有业务逻辑组件
③、SpringMVC配置文件 只是控制网站跳转逻辑 JavaEE——Mybatis（13）--MyBatis与Spring整合--Spring SpringMVC相关配置文件 及Spring整合MyBatis
测试：
1、controller控制器 控制转发逻辑
StudentController
package mybatis.controller;
import mybatis.bean.Student;
import mybatis.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;
import java.util.Map;
@Controller
public class StudentController {
@Autowired
StudentService studentService;
@RequestMapping("/getAllStudents")
public String students(Map<String, Object>map){
List<Student> students = studentService.getAllStudents();
map.put("students", students);
return "list";
}
@RequestMapping("/getById")
public String students1(Map<String, Object>map, Integer id){
Student student = studentService.getStudentById( id );
map.put("student", student);
return "list1";
}
}
2.StudentService 来执行增删改查
package mybatis.service;
import mybatis.bean.Student;
import mybatis.dao.StudentMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("studentService")
public class StudentService {
@Autowired
StudentMapper studentMapper;
public List<Student> getAllStudents(){
return studentMapper.getStudents();
}
public Student getStudentById(Integer id){
return studentMapper.getById( id );
}
}
3.StudentMapper接口和StudentMapper.xml用来真正执行增删改查
StudentMapper接口
package mybatis.dao;
import mybatis.bean.Student;
import java.util.List;
public interface StudentMapper {
public Student getById(Integer id);
public List<Student> getStudents();
}
StudentMapper.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">
<mapper namespace="mybatis.dao.StudentMapper">
<!--public Student getById(Integer id);-->
<select id="getById" resultType="mybatis.bean.Student" parameterType="java.lang.Integer">
SELECT * FROM student WHERE id=#{id}
</select>
<!--public List<Student> getStudents();-->
<select id="getStudents" resultType="mybatis.bean.Student">
SELECT * FROM student
</select>
</mapper>
