Spring JPA (Java Persistence API) provides an abstraction layer over JPA using ORM (Object Relational Mapping). Spring JPA simplifies database interactions by abstracting common operations to simple Java objects and annotations.
This module includes idiomatic examples of Spring JPA with Oracle Database Free.
The com.example.relationships package defines a basic JPA entity and repository, using the student schema.
The SpringJPATest class provides examples of basic JPA repository usage.
The com.example.relationships package defines JPA entities for the movie schema with one-to-one, one-to-many, and many-to-many relationships.
The JPARelationshipsTest class provides examples on managing JPA relationships using repositories.
The com.example.paging package defines JPA entities for the author schema, including repositories with custom JPA methods that utilize paging, sorting, and filtering.
The PagingSortingFilteringTest class provides examples for paging, sorting, and filtering using the Author and Books repositories. Example of JPA @Query annotations, JPA query methods, and specification queries (introduced in JPA 2.0) are included.
