一、新增三个依赖pom.xml，以及yml配置文件，以及在启动类上面加包扫描

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </plugins>
    </build>

</project>

dev.yml

# mybatis 配置文件
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql:///myshop?characterEncoding=UTF-8&useSSL=false
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource


mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.example.gua.pojo
  configuration:
    map-underscore-to-camel-case: true

包扫描

package com.example.gua;

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

@SpringBootApplication
@MapperScan(basePackages = "com.example.gua.mapper")
public class GuaApplication {

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

}

二、测试类

package com.example.gua;

import com.example.gua.mapper.UserMapper;
import com.example.gua.pojo.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;
import java.util.List;

@RunWith(SpringRunner.class)
@SpringBootTest
public class GuaApplicationTests {

    @Resource
    private UserMapper userMapper;

    @Test
    public void findAll() {
        List<User> all = userMapper.findAll();
        System.out.println(all);
    }

}
