Spring Boot with Spring Data JPA (1) - Concept

What's Spring Data JPA?

According to Pivotal, Spring Data JPA, part of the larger Spring Data family, makes it easy to easily implement JPA based repositories. This module deals with enhanced support for JPA based data access layers. It makes it easier to build Spring-powered applications that use data access technologies.

Features

Sophisticated support to build repositories based on Spring and JPA

Support for Querydsl predicates and thus type-safe JPA queries

Transparent auditing of domain class

Pagination support, dynamic query execution, ability to integrate custom data access code

Validation of

@Query

annotated queries at bootstrap time

Support for XML based entity mapping

JavaConfig based repository configuration by introducing

@EnableJpaRepositories

What I am going to explain in this series?

I will build some demonstrations based on spring-data-starter-data-jpa, to show how to adopt these features.

Dive into the source code to study how it works.
