1、导入依赖

        </plugins>
    </build>

</project>

2、实体类

package com.michael.myblog.entity;

/**
 * @ClassName: Customer
 * @Package com.michael.myblog.entity
 * @Description: TODO
 * @Author Mr.Z
 * @Date 2020/7/26 19:56
 * @Version 1.0
 */
public class Customer {
    private String name;
    private String phone;
    private String email;

    //getter、setter方法....
}

3、Mapper类

package com.michael.myblog.dao;

import com.michael.myblog.entity.Customer;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * @ClassName: CustomerMapper
 * @Package com.michael.myblog.dao
 * @Description: TODO
 * @Author Mr.Z
 * @Date 2020/7/26 19:59
 * @Version 1.0
 */
@Mapper
@Repository
public interface CustomerMapper {
    @Select("select * from customer")
    List<Customer> getCustomers();
}

4、controller

@RestController
@RequestMapping("/customer")
public class UserController {

    @Autowired
    private CustomerMapper customerMapper;

    @GetMapping
    public List<Customer> getCustomers() {
        return customerMapper.getCustomers();
    }
}

5、启动类

@SpringBootApplication
@MapperScan("com.michael.myblog.dao") //扫描Mapper类
public class MyBlogApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyBlogApplication.class, args);
    }

}

6、启动成功、访问路径
