mysql报错：java.sql.SQLException: Field 'id' doesn't have a default value

mysql报错：java.sql.SQLException: Field ‘id’ doesn’t have a default value

数据库增加数据报错：java.sql.SQLException: Field ‘id’ doesn’t have a default value
原因是表的id属性没有设置自动递增。

java.sql.SQLException: Field 'id' doesn't have a default value

在设计表的时候，id作为主键勾选自动递增即可解决此问题。
