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.

Unfortunately the links in this answer are dead. – florin Jan 23 '11 at 07:37
@florin, that's the price you sometimes pay for linking outside of SO :-) Actually, the first and the last were still there. The second had moved so I've updated the link. The third I couldn't locate again so I've just deleted it completely. – paxdiablo Jan 23 '11 at 08:12

Though this link demonstrates Visual-Paradigm tool for generating Custom ID generator, but the idea of Hibernate Custom ID generator can be learnt from the same
