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.

But none had the trend-setting notion to help us put together a barebones application directly.

In the past, before Spring Boot entered the scene, we would do one of the following actions to start off a new project:

  • Option 1: Comb through stackoverflow.com, looking for a sample Maven build file
  • Option 2: Dig through reference documentation, piecing together fragments of build XML, hoping they would work
  • Option 3: Search various blog sites authored by renowned experts, praying one of their articles contains build details

Oftentimes, we had to contend with out-of-date modules. We may have attempted to apply a configuration option that no longer existed or did not do whatever we needed it to do.
