This post was worth it even if you only read “Bags don’t need to be loaded when inserts happen”. We had so many problems with performance that were solved when I figured this one out. It was one of those, if I only I’d know this before moments.

As far as I know, the constructor with the right amount of parameters needs to be provided. It would indeed be a nice feature if it would use the getters/setters.

These are really greta techniques that i was unaware of, thanks for bringing them to light.

I tried using HQL new keyword, i wanted just an id and name form one of my objects. But hibernate asked for a valid constructor when i ran a query like one displayed above. It means it requires a constructor which would take such arguments. It did work after overloading my original constructor.

But is’nt there a way without creating this constructor, else we would kep creating such constructor as per number and kind of arguments… I hope my concern is conveyed properly.

Thanks!

I have no idea.
I doubt it however, since the hibernate session is only for attached objects and these aren’t attached.

Great tips! One question, will the results of a query using the ‘new’ keyword to return pojos be cached in the hibernate session and re-used by subsequent calls of the same query?

Persist() vs save() (persist does not cascade)

This is not true, persist does cascade, it cascades the “persist” operation, not the save one

Awesome list. Many of them were eye openers. I agree with you that the best way to learn something is to relearn it
