Overview of this book

Spring Framework has always had a good support for different data access technologies. However, developers had to use technology-specific APIs, which often led to a situation where a lot of boilerplate code had to be written in order to implement even the simplest operations. Spring Data changed all this. Spring Data makes it easier to implement Spring-powered applications that use cloud-based storage services, NoSQL databases, map-reduce frameworks or relational databases. "Spring Data" is a practical guide that is full of step-by-step instructions and examples which ensure that you can start using the Java Persistence API and Redis in your applications without extra hassle. This book provides a brief introduction to the underlying data storage technologies, gives step-by-step instructions that will help you utilize the discussed technologies in your applications, and provides a solid foundation for expanding your knowledge beyond the concepts described in this book. You will learn an easier way to manage your entities and to create database queries with Spring Data JPA. This book also demonstrates how you can add custom functions to your repositories. You will also learn how to use the Redis key-value store as data storage and to use its other features for enhancing your applications. "Spring Data" includes all the practical instructions and examples that provide you with all the information you need to create JPA repositories with Spring Data JPA and to utilize the performance of Redis in your applications by using Spring Data Redis.

This book covers the 1.2.0.RELEASE version of Spring Data JPA, which is the newest available version during the authoring of this book. The other components required by Spring Data JPA are described in the following table:




Data source

BoneCP is a fast connection pool library that is used as a data source for our application.


JPA provider

A JPA provider is a library that implements the Java Persistence API. We will use Hibernate as a JPA provider.


Spring Framework

Spring Framework is used to develop modern enterprise applications with Java.



H2 is an embedded in-memory database that supports standard SQL and the JDBC API.


We will use the newest available version of our application's other dependencies.

We can download the required dependencies with Maven by declaring them in the POM file. In order to do this, we have to add the following dependency declarations...
