在使用MP的时候给Warning了

WARNWarn: Could not find @TableId in Class: com.fehead.OceanCode.dataobject.GroupFileDO.
WARNWarn: Could not find @TableId in Class: com.fehead.OceanCode.dataobject.GroupInfoDO.
WARNWarn: Could not find @TableId in Class: com.fehead.OceanCode.dataobject.GroupUserDO.
WARNWarn: Could not find @TableId in Class: com.fehead.OceanCode.dataobject.UserInfoDO.

找了一大圈原因发现没有在实体类的自增主键上加自增主键的注解

@TableName("file_info")
public class FileInfoDO {

    @TableId(value = "id",type = IdType.AUTO)//在自增主键的变量加上即可
    private Integer fileId;
    }

这个坑太坑了,找了一晚上!
