Alex Kalinovsky commented on HBX-733:
-------------------------------------

I have submitted a patch more then 2 months ago. We are not in production using the code generator and it works GREAT! It's easy to maintain the generated model objects and DAOs because we generate a regeneratable base class and a customizable subclass. Any database changes can be synched up. Same is done for DAOs. I've added generation of Mock DAOs and unit tests so our entire persistence layer is generated. Saved a ton of time.

I am also generating POJO services synched up with DAOs and Spring context that wires it all together.

I don't know why the patch hasn't been accepted yet because while it may not be perfect, it is clearly much better then the current DAO generation. I was willing, and I am still willing, to integrate it into Hibernate Tools.

> This should be a complete implementation of DAO generation according to the design we have discussed over the email. I've tested this on our project so the DAOs should be good to go, but of course a more diverse testing would be needed before releasing it to public. I'm open for recommendations and suggestions, so I see this as the first draft. Below is a list of files and comments. Contact me at kalinovsky at yahoo.com.
