Hibernate and Spring Data JPA: Beginner to Guru

Master Hibernate, the most popular Java ORM – Remove the mystery of Spring Data JPA

Hibernate is the default JPA implementation used by Spring Data JPA. JPA stands for Java Persistence API. This is a common Java API used to work with Relational Databases. Spring Data JPA is an abstraction built on top of the JPA API specification. Being an abstraction, Spring Data JPA makes working with database entities very efficient. Spring Data JPA eliminates a lot of the boilerplate / cerimonial code, and allows developers to focus on developing business logic. The downside of the efficient abstraction is that accessing the database can become a mystery. Developers who just understand how to use Spring Data JPA do not understand the complexities of JDBC and Hibernate.
