休眠ID生成器 [英] Hibernate ID Generator

问题描述

任何人都知道一些关于如何为hibernate创建自定义ID生成器的好教程？ 解决方案

粗略搜索Google对于hibernate自定义id生成器教程，出现以下几种可能性。我已经排除了那些看起来不太有用的内容，并总结了每个内容。

• http://www.devx.com/Java/Article/30396 - 涵盖了在数据持续存在之前生成ID的问题（因此还没有商业密钥）。


• http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html_single/#mapping-declaration - 整个文档是非常有用的，但不是一个教程作为参考。在查看其他教程时非常理想。


• http://www.javaworld.com/javaworld/jw-08-2008/jw-08-hibernate-annotations.html 显示了如何使用注释来设置您的模式（包括自动生成的值）。

希望有帮助。

Anyone know of some good tutorials on how to create a custom ID generator for hibernate?

解决方案

A cursory search of Google for 'hibernate custom id generator tutorial' turned up the following possibilities. I've excluded those that don't look useful and summarized the content of each.

• http://www.devx.com/Java/Article/30396 - covers the issues of generating an ID before the data is persisted (and hence does not yet have a business key).
• http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html_single/#mapping-declaration - the whole document is very useful but not so much a tutorial as reference. Ideal when looking at the other tutorials.
• http://www.javaworld.com/javaworld/jw-08-2008/jw-08-hibernate-annotations.html shows how to use annotations to set up your schema (including auto-generated values).

Hope that helps.
