Spring 5.0 Cookbook

Overview of this book

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs. The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face. Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications. By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.

Preface

Implementing Spring Data with JPA


Spring Boot 2.0 still supports persistence using JPA, which avoids too many SQL scripts and Hibernate configurations. It provides auto-configuration when it comes to creating a persistence layer and, thus, it is an option to auto-configure the hibernate.properties and some JPA details. This recipe will illustrate how reactive applications can integrate with a non-reactive Spring Data JPA for MySQL CRUD transactions.

Getting started

Open ch09-flux and add a Spring Data JPA module for persistence and transaction management.

How to do it...

Spring 5 still supports Spring Data modules including Spring Data JPA. This recipe will showcase how to integrate Spring Data JPA using Spring Boot 2.0:

  1. First, add the following starter POM dependency for Spring Data JPA auto-configuration:
<dependency> 
   <groupId>org.springframework.boot</groupId> 
   <artifactId>spring-boot-starter-data-jpa</artifactId> 
</dependency> 
  1. Inside the package...
