我正在尝试使用 Hibernate/Jpa 设置一对多关系。
目前我遇到了这个异常:
Invocation of init method failed; nested exception is org.hibernate.HibernateException: Missing table: refund_transaction_item_refund_detail

我知道我在 @OneToMany 或 @ManyToOne 注释中犯了一些错误。
更新: 我的数据库中只有 2 个表，refund_transaction 和 item_refund_detail。而且我没有任何名为 refund_transaction_item_refund_detail 的表。规范化架构后，我在 item_refund_detail 表中添加了 refund_request_id 以维护关系。 也许我需要维护单向映射才能实现这一点。请指教。
最佳答案
你做错了很多事情。一些要点:
- 您正在使用字段访问权限和属性访问权限。您必须选择一种样式作为默认样式(然后您可以使用
AccessType覆盖默认样式以获得所需的属性)。 @ElementCollection用于嵌入集合，因此会出现错误。为此，您应该使用@OneToMany。- 不要忘记将双向关联的一侧声明为反向关联(在
@OneToMany关系的情况下，通常是One上的实体侧)。
关于java - 使用 Hibernate、JPA 建立一对多关系，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35040925/
