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.

Summary

In this chapter, we learned several key skills, including creating a reactive application using Project Reactor, rolling out a reactive web method to both serve and consume JSON, and how to leverage Thymeleaf to reactively generate HTML and consume an HTML form. We even used Spring HATEOAS to reactively generate a hypermedia-aware API.

All these features are the building blocks of web applications. While we used a Java 8 functional style to chain things together, we were able to reuse the same Spring Web annotations we’ve used throughout this book.

And by using Reactor’s style, a paradigm quite similar to Java 8 Streams, we can potentially have a much more efficient application.

That concludes this chapter! In the next chapter, we will wrap things up by showing you how to reactively work with real data.
