Subject: Re: [Middlegen-user] hibernateDAO failing to
generate findBy method for primary key
... I would love to hear some more comments on the
hibernateDAO> piece
My goal is not not have every possible combination of methods
generated, but if we could get like 70%(save/delete/findByPK,
findBySingleColumn)
What else would you like to see?
pm4jih, i have not used middlegen for a while (and that was just to
reverse). But was trying to learn how to write dao's. I ended up with a pair
of inerfaces (please see below). I am a newbie to this stuff, and all of
this will have problems trying to be abstracted above hibernate in to dao
(for spring) and I'm sure it contains more than your 70% goal. This was for
a real anemic domain model (1 pojo - 1 table), so take it with a grain of
salt. But it does seem like mostly boilerplate and helper methods, so maybe
some of methods might be candidates for your 70%.
thanks
