问题描述
这与，因为我需要一个没有连接表的@OneToMany关系。但是，我也不想定义反比关系。删除反向似乎会导致一个连接表被自动生成...有没有解决这个问题的方法？
This is a similar problem to "Hibernate @OneToMany without a separate join table", in that I need a @OneToMany relationship without a join table. However, I would also like to not define the inverse relationship. Removing the inverse seems to result in a join table being automatically generated... is there a workaround for this?
推荐答案
在JPA 2.0+，您可以使用@JoinColumn作为避免生成连接表的方式。
In JPA 2.0+ you can use @JoinColumn as a way to avoid to generate joined table.
试试看。
@OneToMany
@JoinColumn(name="COLUMN_NAME")
更新
以上提供的信息已从EJB 3.0 o'reilly书中提取（查找@JoinColumn注释引用PHONE表中的CUSTOMER_ID列）。但是，普通的JPA 1.0规范不支持此功能。它说的是
The info provided above has been extracted from EJB 3.0 o'reilly book (Look for The @JoinColumn annotation references the CUSTOMER_ID column in the PHONE table). However, plain JPA 1.0 specification does not support this feature. What it says is
所以在1.0中是它是一个特定于供应商的实现（它是有道理的，作者在JBoss工作 - 在hibernate后面的红帽子部分）
So in 1.0 it is a vendor-specific implementation (And it makes sense, The author works at JBoss - The red hat divison behind the hibernate)
但它由JPA 2.0实现支持

But it is supported by JPA 2.0 implementation
