当程序报错 Field ‘id’ doesn’t have a default value] with root cause时，很明显可以看到是我们没有给表id赋值，但是我们的数据库却设置id不能为空。所以就会报错字段“id”没有默认值] 根本原因，解决办法一共两步。
1、在数据库中表id设置为自动递增
![Field 'id' doesn't have a default value] with root cause](https://www.itshiye.com/wp-content/uploads/2023/03/Snipaste_2023-03-09_18-48-31.png "Field 'id' doesn't have a default value] with root cause")
2、在代码中配置id为自增 @TableId(value = “id”, type = IdType.AUTO)
![Field 'id' doesn't have a default value] with root cause](https://www.itshiye.com/wp-content/uploads/2023/03/Snipaste_2023-03-09_18-50-09.png "Field 'id' doesn't have a default value] with root cause")
正文完
Field ‘id’ doesn’t have a default value] with root cause
