描述清楚上下文，直接一堆异常，都不知道你做了啥呢

• 提问者 慕田峪0177977 #1

  我在MetaDatabaseServiceTest.java中运行testSave()进行单元测试时报错，错误信息为"Field 'id' doesn't have a default value",另外，我在终端运行"desc meta_database"命令时，id的extra中没有看到自动自增，我想时这bug可能跟id的自动递增的设置有关，但不知怎么添加

• Michael_PK 回复 提问者 慕田峪0177977 #2

  你的对象里面的id属性添加了自增的注解了吗？
  git上有源码，可以对比下

• 提问者 慕田峪0177977 回复 Michael_PK #3

  可以了，感觉可能是之前没加@Id
      @GeneratedValue时运行过一次MetaDatabase.java，再创建时原先的表没被覆盖，然后我把之前那张表删了，重跑了一下MetaDatabase.java和MetaDatabaseServiceTest.java就通了
