为什在测试successSeckill的时候查出来的是null,前面测试insert已经成功数据库也有相应的字段
测试类-----------------------
@Test
public void testInsertSuccessKilled() {
long userPhone = 13550922395L;
long seckillId = 9998L;
int count = successKillDao.insertSuccessKilled(seckillId, userPhone);
System.out.println("count = " + count);
}
@Test
public void testQueryByIdWithSecKill() {
long userPhone = 13550922395L;
long seckillId = 9998L;
SuccessKilled successSeckill = successKillDao.queryByIdWithSecKill(seckillId, userPhone);
System.out.println(successSeckill);
}

<!-- 根据查询successKilled同时并携带seckill实体 -->
<!-- 如果告诉mybatis把结果集映射到seccessKilled同时映射到seckill属性 -->
<!-- 可以自由控制SQL -->
