Overview of this book

Spring Boot provides a variety of features that address today's business needs along with today's scalable requirements. In this book, you will learn how to leverage powerful databases and Spring Boot's state-of-the-art WebFlux framework. This practical guide will help you get up and running with all the latest features of Spring Boot, especially the new Reactor-based toolkit. The book starts off by helping you build a simple app, then shows you how to bundle and deploy it to the cloud. From here, we take you through reactive programming, showing you how to interact with controllers and templates and handle data access. Once you're done, you can start writing unit tests, slice tests, embedded container tests, and even autoconfiguration tests. We go into detail about developer tools, AMQP messaging, WebSockets, security, and deployment. You will learn how to secure your application using both routes and method-based rules. By the end of the book, you'll have built a social media platform from which to apply the lessons you have learned to any problem. If you want a good understanding of building scalable applications using the core functionality of Spring Boot, this is the book for you.

In the previous chapter, you learned how to use Spring Boot's various testing features. We saw how to craft simple unit tests, slice tests, mock WebFlux tests, and even fully spun-up embedded Netty integration tests.

When we get into the swing of things, anything that can bend the curve of time spent building an app is appreciated. We will explore the various tools Spring Boot brings to the table to help us hack away at our applications.

In this chapter, we will do the following:

  • Using Spring Boot's DevTools for hot code reloading and decaching
  • Glean what Spring Boot did with its autoconfiguration report
  • Make local changes and see them on the target system
  • Write a custom health...
