我收到以下错误

我使用的是liferay 6.2。它在服务构建器中没有映射键，因此我在数据库表中手动给出了引用。 引用是正确的，我不明白它给出错误的原因。

ALTER TABLE `audit_compliance`.`audit_compliance_auditdetailes` 
DROP FOREIGN KEY `documentCollectionIds`;
ALTER TABLE `audit_compliance`.`audit_compliance_auditdetailes` 
ADD CONSTRAINT `documentCollectionIds`
FOREIGN KEY (`documentCollectionIds`)
REFERENCES `audit_compliance`.`audit_compliance_documentcollection` (`name`);

由于 ServiceBuilder 不包含外键引用，因此它可能会使用错误的顺序将数据插入表中:现在您强制执行外键关系，但 ServiceBuilder 仍然不知道这一点。

决定是使用 ServiceBuilder 的持久性(那么您可能不想使用外键)还是自行推出。您仍然可以将 ServiceBuilder 用于服务层，并在后台使用您自己的持久性。
