public class UserServiceTest {
    @Autowired
    private UserService userService;

    @Test
    public void methodTest(){
        userService.method();
    }
}

spring-boot整合mybatis

application.yaml文件配置

spring:
  datasource:
    url: jdbc:mysql:///bookdb?serverTimezone=UTC
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver
mybatis:
  type-aliases-package: com.example.demo.bean
  #mapper-locations: classpath:映射文件路径，如果mapper.xml和Mapper接口在同一目录下则不用配置
  #config-location: 指定mybatis的配置核心文件

mapper.xml文件配置

<?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="com.example.demo.mapper.UserMapper">
    <select id="queryAll" resultType="UserInfo">
        select * from userinfo
    </select>
</mapper>

mapper接口文件

@Component
@Mapper
public interface UserMapper {
    List<UserInfo> queryAll();
}

测试类的编写

@RunWith(SpringRunner.class)
