特定于包的 Hibernate NamingStrategy

发布于 2024-10-03 18:00:55 字数 811 浏览 1 评论 0原文

鉴于大型应用程序的不同包中存在多个 Hibernate 实体，我想确保不存在命名冲突。例如，包 foo 中可能有一个 Person-Entity，而包 bar 中可能有另一个 Person-Entity。

现在这两个实体应该映射到这样的表名称：

foo.Person --> FOO_PERSON
bar.Person --> BAR_PERSON

我可以使用 @Table-annotation 来实现这一点：

@Table(name="FOO_PERSON")
public class Person ...

@Table(name="BAR_PERSON")
public class Person ...

但是，我想使用某种 NamingStrategy，它会自动执行此操作。 Hibernate 提供了接口 org.hibernate.cfg.NamingStrategy。我尝试扩展 DefaultNamingStrategy，但是（尽管文档另有说明）您只能获得类的非限定名称，因此没有有关包名称的信息。

有一个 JIRA 问题（http://opensource.atlassian.com/projects/hibernate /browse/HHH-4312）关于这个问题。鉴于它自 2007 年以来一直开放，我正在寻找一种解决方法或完全不同的方法。有什么想法吗？

原文

Given several Hibernate entities in different packages of a large application, I like to make sure, that there are no naming conflicts. E.g. there could be a Person-Entity in package foo and another Person-Entity in package bar.

Now this two entities should map to table names like this:

foo.Person --> FOO_PERSON
bar.Person --> BAR_PERSON

I could use the @Table-annotation to achieve this:

@Table(name="FOO_PERSON")
public class Person ...

@Table(name="BAR_PERSON")
public class Person ...

However, I'd like to use some kind of NamingStrategy, that does this automatically. Hibernate offers the interface org.hibernate.cfg.NamingStrategy. I tried to extend the DefaultNamingStrategy, however (despite the documentation stating otherwise) you only get the unqualified name of the class and therefore no information about the package name.

There is a JIRA issue (http://opensource.atlassian.com/projects/hibernate/browse/HHH-4312) about this problem. Given, that it is open since 2007, I'm looking for a work-around or a totally different approach. Any ideas?
