springboot-mybatis 使用junit4 单元测试，单独启动mybatis

1. 首先再pom加入mybatis test 的jar包

    org.mybatis.spring.boot
    mybatis-spring-boot-starter-test
    1.3.2
    test

2. 增加单元测试类

//@SpringbootTest
@MybatisTest    //缓存mybatsitest注解
@RunWith(SpringJUnit4ClassRunner.class)
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)    //这个是启用自己配置的数据元，不加则采用虚拟数据源
@Rollback(false)    //这个是默认是回滚，不会commit入数据库，改成false 则commit
public class MapperTest {
    @Resource
    Mapper mapper;

    @Test
    public void testInsert(){
        Entity entity = new Entity();
        entity.setAct("res");
        int insert = mapper.insert(entity);
        System.out.println(insert);
        System.out.println(entity.getId());
    }

3. mybatis 注解式sql编写

@Insert({"insert into otp_statistics ( ACT ) VALUES ( #{act} ) "})
// @SelectKey(statement = "SELECT LAST_INSERT_ID()", keyProperty = "id", resultType = Integer.class, before = false)    //返回插入的id，放入entity入参中
    @Options(useGeneratedKeys = true , keyProperty = "id")    //只能再自增id中用，返回插入的id，放入entity入参中
    int insert(OtpStatisticsEntity entity);
