我在我的项目中使用JPA + Spring Boot，这是我第一次使用JPA，我对Spring Boot也是个新手。
我想创建两个表file_perms和file_perm_values，我可以正确地定义file_perms，但是，对于我的第二个表file_perm_values，我想定义一个由file_perms的主键组成的复合主键，即：id和另一个字符串file_id。当我编写如下所示的定义并使用Intellij的DDL创建按钮时，得到错误Caused by: java.lang.IllegalStateException: The column type is undefined. Table - file_perm_values; Column - file_perm_id
我哪里做错了？
能不能请一些Maven帮我弄清楚问题是什么以及如何解决这个问题？
我会非常感激的
