2.实体类

@Data
    public class UserInfoDO { 
    
        private Long id;
    
        private String name;
    
        private Integer age;
    }

3.mapper层

package h2demo.mapper;
    
    import org.apache.ibatis.annotations.Mapper;
    
    @Mapper
    public interface UserInfoMapper { 
    
        int deleteById(Long id);
    }

4.mapper.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="h2demo.mapper.UserInfoMapper">
    
        <delete id="deleteById" parameterType="java.lang.Long">
            delete from user_info where id=#{ id}
        </delete>
    </mapper>

5.application.properties

spring.application.name=h2-test-demo
    # 数据库配置
    spring.datasource.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;MODE=MySQL
    spring.datasource.username=
    spring.datasource.password=
    spring.datasource.driver-class-name=org.h2.Driver
    spring.datasource.schema=schema.sql
    spring.datasource.data=data.sql
    
    #mybatis配置
    mybatis.config-location=classpath:mybatis/mybatis-config.xml
    mybatis.mapper-locations=classpath*:mybatis/mappers/*.xml

6.BaseTest.java

package h2demo.mapper;
    
    import org.junit.runner.RunWith;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
    public class BaseMapperTest { 
    }

7.测试

package h2demo.mapper;
    
    import org.assertj.core.api.Assertions;
    import org.junit.Test;
    
    import javax.annotation.Resource;
    
    
    public class UserInfoMapperTest extends BaseMapperTest { 
    
        @Resource
        private UserInfoMapper userInfoMapper;
    
        @Test
        public void deleteById() { 
            int rows = userInfoMapper.deleteById(1L);
            Assertions.assertThat(rows).isGreaterThan(0);
        }
    }
