We have to support both MySQL and MSSQL so Hibernate has been mostly great for that. For really simple queries it's also nice to be able to write "findAllBySomethings_IdAndPropertyIsNull" etc instead of writing a SQL query. Been there, done that.

Though I have to admit I do check what queries Hibernate produces to make sure it's not doing some funky stuff that's not really needed (as a result of a mistake of my own, mostly)

Edit: It has come to my attention that it is ofcourse Spring Data that offers those named queries. Still see nothing wrong with hibernate since I still only have to write it once and I'll be relatively safe supporting both db systems.
