PreparedStatement.RETURN_GENERATED_KEYS使用时出现Field 'id' doesn't have a default value错误

使用PreparedStatement.RETURN_GENERATED_KEYS 可以获得刚刚插入自增ID不容置疑;
可是运行之后总是报一个叫java.sql.SQLException: Field 'id' doesn't have a default value 的错误 ,开的程序好多遍没有解决问题 !!!
最后怀疑是数据库问题,于是乎就去看看数据库设置........
竟然没有选择自增,故PreparedStatement.RETURN_GENERATED_KEYS 无法使用.
吸取教训啊...
