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
然后这个是tb_person_info的数据
这个是ShopDao.xml插入的语句

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:

在向tb_shop中插入数据时,设置owner的id为1,如:

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~
