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.

One of the biggest issues in getting to the heart of problems is knowing what version is running! Have you ever gotten a 3:00 a.m. call from a customer reporting that the system is broken? In a half-awake state, it's easy to start trying to solve the problem only to discover two hours later, the customer is running an older version and that their issue was patched last week.

The solution is embedding precise versions in every release so that the customer can relay this over the phone. Then, we can quickly figure out if this issue is new, fixed, or a regression. Interested?

Just add this to the build.gradle file, right below the buildscripts section:

    id "com.gorylenko.gradle-git-properties" version "1.4.17" 

This will add a new task, generateGitProperties, to our system. Anytime we engage Gradle to build the app...
