Spring Boot应用程序-SQLException：无法添加外键约束

时间：2018-11-11 20:38:20

标签： mysql spring spring-boot foreign-keys

对这个问题进行了一些研究之后，我发现数据库结构中可能存在某些错误，因此我尝试使用“ SHOW ENGINE INNODB STATUS”命令来找出导致外键SQLException的原因。 > Here is the result on "lastest foreign key error"
如果我是对的，那么导致问题的表就是临时表，这就是为什么我不知道该怎么办的原因。 这里的其他问题通常就像在一个表中有一个unsigned int，并在外键上对int进行签名，这样会导致错误，但是我在脚本中看不到类似的内容，并且脚本本身在mysql工作台中可以正常工作，但是使用此数据库时，spring应用程序将引发异常。
奇怪的是我的代码中没有任何地方的origin_id，无论是Java代码还是sql。
这是数据库脚本：
