I have not used Spring Data before but I've used Hibernate ORM a number of times for MySQL based application. I just don't understand which framework to choose between the two for a MongoDB based application.
I've tried searching for the answer but I can't find the answer which does a comparison between the two in a production environment. Has anyone found problems working with these two frameworks with MongoDB ?
Spring Data JPA helps you to connect to relational databases using ORM frameworks. The default JPA implementation used is Hibernate. The core interface is the JpaRepository.
Yes, DataNucleus JPA allows it, as well as to many other databases.
Spring Data for MongoDB is part of the umbrella Spring Data project which aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities.
How to use Hibernate OGM with MongoDB? To get started with Hibernate MongoDB, you first need to build the OGM from Source via GitBug. To include OGM in your Hibernate MongoDB project, just include one more dependency in your list of dependencies. Next, to define the persistence unit, create a META-INF/persistence.
Disclaimer: I am the lead of the Spring Data project, so I'll mostly cover the Spring Data side of things here:
I think the core distinction between the two projects is that the Hibernate OGM team chose to center their efforts around the JPA while the Spring Data team explicitly did not. The reasons are as follows:
So with Spring Data, we chose to rather provide a consistent programming model for the supported stores but not try to force everything into a single over-abstracting API: you get the well-known template implementations, you get the repository abstraction, which works identical for all stores but lets you leverage store-specific features and concepts.
