Hibernate custom identifier generattion

Question

Hi, I am now using hibernate as ORM technique in my application. I have a table called Order and I want the hibernate to generates the ID for each instance when inserting new order into the table. Quite unusual, the desired auto-generated id should be something like this:

first time: jialhe001 and then jialhe002 .... jialhe003, jialhe004......

How can I realize that? I have found some articles talking about creating a new class which implements the identifier generator interface and override a method.

However, the explanation is quite general no detailed thing. Can anyone tell me how to do that? Preferably, code sample is highly requested. Thank you in advance.

I'd argue that you should not use such primary keys if you can use a simple auto_increment. If your application needs the string jialhe00x then concatenate jialhe with the auto-incremented ID.

You didn't say which articles you read, so check this one
