How to start learning Hibernate?

Question

Java

Hello!
I'm learning java, recently I decided to burden myself with learning hibernate. I looked - gasped: so many things, the devil will break his leg. A question for experienced people: what is the minimum you need to know at the junior level, the minimum base?

Answer 1

At the very least, you need to know how to perform CRUD operations using hibernate. Ideally, what you can do with the sql database you need to be able to organize in the ORM.

Answer 2

If you are suddenly familiar with Php, then you can master doctrine2 - it is very, very similar to hibernate - even the annotations are the same.
You can just look at the doctrine2 documentation and its examples.
Entity creation, relationships, and fetching in doctrine2 and hibernate are similar to 99.9.
I agree that it is not entirely correct to send to study another product, but doctrine with documentation is doing much better, and the difference between them will not be visible at first.
