How to start learning spring + hibernate?

Question

Java

Good afternoon. After studying java core, I realized that I need to learn spring + hibernate. Found the petclinic spring project - https://github.com/spring-projects/spring-petclinic . I partly understood what it is and how it works, but as I started trying to write something myself from scratch, I copy pom.xml, I create a component scanner, controllers, I seem to understand what is needed for what, and when I try to start the trouble.

Tell me where to start studying these frameworks in order to understand at least something in these errors.

Answer 1

From reading the textbooks Ottinger, Minter, Linwood - "Beginning Hibernate" and Craig Walls - "Spring in Action"

Answer 2

The spring site has good guides on specific beans like spring rest, spring data, etc. For example : https://spring.io/guides/gs/rest-service/
There is also full documentation
https://spring.io/docs
. I don’t know, however, how relevant they are for the latest versions of frameworks.
Try also to create a project from scratch using the tool https://start.spring.io/
in which you select the components that you want to study.
