Overview of this book

With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The book has three parts, where each one covers the building of a comprehensive project in Java and Spring. In the first part, you will construct a CMS Portal using Spring's support for building REST APIs. You will also learn to integrate these APIs with AngularJS and later develop this application in a reactive fashion using Project Reactor, Spring WebFlux, and Spring Data. In the second part, you’ll understand how to build a messaging application, which will consume the Twitter API and perform filtering and transformations. Here, you will also learn about server-sent events and explore Spring’s support for Kotlin, which makes application development quick and efficient. In the last part, you will build a real microservice application using the most important techniques and patterns such as service discovery, circuit breakers, security, data streams, monitoring, and a lot more from this architectural style. By the end of the book, you will be confident about using Spring to build your applications.

Persistence with Spring Data and Reactive Fashion

In the previous chapter, we created our Content Management System (CMS) application. We also introduced REST (Representational State Transfer) support in Spring, which enabled us to develop a simple web application. Also, we learned how dependency injection works in the Spring Framework, which is probably the most famous feature of the framework.

In this chapter, we will add more features to our application. Systems in the real world need to persist their data on a real database; this is an essential characteristic for a production-ready application. Also, based on our model, we need to choose the correct data structure to achieve performance and avoid the impedance mismatch.

In the first part of this chapter, we will use the traditional SQL database as a store for our application. We will deep dive on the Spring Data...
