spring.datasource.url=jdbc:mysql://localhost:3306/blog
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3：实体 

package com.mybatis.entity;


/**
 * Created by mark on 2017/3/27.
 * 创建一个User实体类
 */

public class User{
    private Long id;
    private String name;
    private Integer age;

    public Long getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
}

　　

4：mapper

package com.mybatis.mapper;

import com.mybatis.entity.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

/**
 * Created by mark on 2017/3/27.
 * 定义一个DAO的接口
 */
@Mapper
public interface UserMapper {
    @Select("select * from user where name=#{name}")
    User findByName(@Param("name") String name);

    @Insert("INSERT INTO USER(NAME, AGE) VALUES(#{name}, #{age})")
    int insert(@Param("name") String name, @Param("age") Integer age);
}

5：controller

package com.mybatis.controller;

import com.mybatis.entity.User;
import com.mybatis.mapper.UserMapper;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;


/**
 * Created by mark on 2017/3/27.
 */
@RestController
@RequestMapping("/user")
public class UserController {
    @Autowired
    UserMapper userMapper;

    @RequestMapping("index")
    @ResponseBody
    public String index(){
        User user = userMapper.findByName("mark");
        return "name:"+user.getName()+" age:"+user.getAge();
    }
}

6：项目结构

7：编辑器配置

8：启动主程序后  http://localhost:8080/user/index 结果
