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.

Pushing app to Cloud Foundry and adjusting the settings

Keep calm and cf push.

If there's one thing critical to any smooth-running Ops center, it's the need for automation. If we do things by hand, we introduce the risk of drift among our various components in production.

The following section shows some BASH scripts for deploying our microservices-based social media platform, a first step on the path towards automated deployment.

Assuming we've built everything with Gradle, let's kick things off by deploying our Spring Boot uber JARs to Cloud Foundry:

#!/usr/bin/env bash 
cf push learning-spring-boot-config-server -p config-server/build/libs/learning-spring-boot-config-server-0.0.1-SNAPSHOT.jar & 
cf push learning-spring-boot-eureka-server -p eureka-server/build/libs/learning-spring-boot-eureka-server-0.0.1-SNAPSHOT.jar &amp...
