Overview of this book

The Spring framework provides great flexibility for Java development, which also results in tedious configuration work. Spring Boot addresses the configuration difficulties of Spring and makes it easy to create standalone, production-grade Spring-based applications. This practical guide makes the existing development process more efficient. Spring Boot Cookbook 2.0 Second Edition smartly combines all the skills and expertise to efficiently develop, test, deploy, and monitor applications using Spring Boot on premise and in the cloud. We start with an overview of the important Spring Boot features you will learn to create a web application for a RESTful service. Learn to fine-tune the behavior of a web application by learning about custom routes and asset paths and how to modify routing patterns. Address the requirements of a complex enterprise application and cover the creation of custom Spring Boot starters. This book also includes examples of the new and improved facilities available to create various kinds of tests introduced in Spring Boot 1.4 and 2.0, and gain insights into Spring Boot DevTools. Explore the basics of Spring Boot Cloud modules and various Cloud starters to make applications in “Cloud Native” and take advantage of Service Discovery and Circuit Breakers.

Using Remote Update

With the growing popularity of Docker, more and more applications are being built and deployed as Docker containers. One of the great features of Docker is the isolation of the runtime environment from the host OS, but that same isolation makes it difficult to make continuous changes and test your application in a true environment. Each time there is a change to a property file or a Java class, one needs to rebuild everything, create a new Docker image, restart the container, and so on. That's a lot of work to be doing for every change.

Even though, unfortunately, as of version 2.0, Spring Boot has removed the capability of doing a remote debug, there is still the very helpful ability to remotely reload the code changes from within your IDE as you work on the code, without the need to at least rebuild the application JAR and Docker image.
