Overview of this book

Spring Boot is a lightweight framework that provides a set of tools to create production-grade applications and services. Spring Boot 2.0 Projects is a comprehensive project-based guide for those who are new to Spring, that will get you up to speed with building real-world projects. Complete with clear step-by-step instructions, these easy-to-follow tutorials demonstrate best practices and key insights into building efficient applications with Spring Boot. The book starts off by teaching you how to develop a web application using Spring Boot, followed by giving you an understanding of creating a Spring Boot-based simple blog management system that uses Elasticsearch as the data store. Next, you’ll build a RESTful web services application using Kotlin and the Spring WebFlux framework - a new framework that enables you to create reactive applications in a functional way. Toward the last few chapters, you will build a taxi-hailing API with reactive microservices using Spring Boot, in addition to developing a Twitter clone with the help of a Spring Boot backend. To build on your knowledge further, you’ll also learn how to construct an asynchronous email formatter. By the end of this book, you’ll have a firm foundation in Spring programming and understand how to build powerful, engaging applications in Java using the Spring Boot framework.

Using Spring Data JPA for persistence

In this section, readers will learn what JPA is, as well as how Spring Data JPA helps simplify the development of applications with database persistence.

Understanding the Java Persistence API (JPA)

JPA provides object/relation mapping capabilities to enable mapping between relational database tables and Java objects in order to ease persistence in Java applications. JPA consists of the following features:

  • A query language to enable querying from relational database tables in order to retrieve Java objects
  • A JPA Criteria API, which can be used to generate queries dynamically
  • A set of metadata defined with XML Java annotations in order to successfully map relational database table columns...
