Learning Spring Boot 3.0 - Third Edition

By: Greg L. Turnquist

Overview of this book

Spring Boot 3 brings more than just the powerful ability to build secure web apps on top of a rock-solid database. It delivers new options for testing, deployment, Docker support, and native images for GraalVM, along with ways to squeeze out more efficient usage of existing resources. This third edition of the bestseller starts off by helping you build a simple app, and then shows you how to secure, test, bundle, and deploy it to production. Next, you’ll familiarize yourself with the ability to go “native” and release using GraalVM. As you advance, you’ll explore reactive programming and get a taste of scalable web controllers and data operations. The book goes into detail about GraalVM native images and deployment, teaching you how to secure your application using both routes and method-based rules and enabling you to apply the lessons you’ve learned to any problem. If you want to gain a thorough understanding of building robust applications using the core functionality of Spring Boot, then this is the book for you. By the end of this Spring Boot book, you’ll be able to build an entire suite of web applications using Spring Boot and deploy them to any platform you need.

In the previous chapter, we learned about all the various ways we could configure our application using Spring Boot. This unlocked the ability to run our application in multiple environments, which made it more flexible.

The most critical place for our application to be is in production. Otherwise, it’s not doing what we set out to do. Production can be a scary place. The Spring team, in its battle-hardened experience, has built many features into Spring Boot to ease the processes involved with assembling applications, staging, and ultimately managing them once deployed.

Building upon the tools covered in the previous chapter, we’ll see how Spring Boot can turn what used to be a scary place to be into a thriving environment.

In this chapter, we’ll cover the following topics:

  • Creating an uber JAR
  • Baking a Docker container
  • Releasing your application to Docker Hub
  • Tweaking things in production
  • ...
