Question

I’m using Hibernate in a project, and I have to search for Objects in the Database by inserting some constraints.
I want the search procedure to return a row containing the id of the Object, some information on childs entities and, most important, something describing why the row is present in the result, for example a list of pair (matched entity, matched property) including matched child.
I already did it in plain sql, and it’s tedious. I think i would be able do do it using hibernate hql too, but it sounds like I’m rewriting the same thing, just in a slighty different language. My question is : There’s a way do do it cleanly, using criteria, with as least sql query as possible?
I know that the question is very wide so notice that here I’m searching for advices, tips, best practice, not for complete implementations. Something we can elaborate on later to find a good solution…
Thank you in advance..

Answer 1

there is query by example where you can give hibernate an example of the entities it should look for. maybe you could the compare the results with the example.

Example example = Example.create(exampleobj)...; // add configs how to work with the example
Criteria crit = currentSession.createCriteria(Mitarbeiter.class).add(example);
