貌似是外键错误,但是我看了一下表结构感觉没问题啊

这个是我的tb_shop表的建表语句

http://img.mukewang.com/climg/5e0d6323097d1b1508000724.jpg然后这个是tb_person_info的数据

http://img.mukewang.com/climg/5e0d637d093b191c14530412.jpg这个是ShopDao.xml插入的语句

http://img.mukewang.com/climg/5e0d63c209864f4512490700.jpg

这个是测试插入的代码

同学你好,报错提示是外键约束错误,但不是表结构错误,而是数据错误。tb_shop表中owner_id参照tb_person_info表中的user_id。

在tb_shop_info表中,有一条数据,user_id是40,如:

http://img.mukewang.com/climg/5e0d8da00953136f06530299.jpg

在向tb_shop中插入数据时,设置owner的id为1,如:

http://img.mukewang.com/climg/5e0d8ded09c2f36405920311.jpg

这个id为1的owner在tb_person_info表中不存在,所以提示外键约束错误。

建议同学设置owner.setUserId为40L再试试。

如果我的回答解决了你的疑惑,请采纳。祝:学习愉快~
