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.

Using start.spring.io to augment an existing project

What if we already started a project and have been working hard on it for the past six months? Creating a brand-new project makes no sense, right?

So, what can we do?

It’s possible to pick up an already existing project and make alterations using start.spring.io.

We started this chapter with nothing but Spring Web. While we could get pretty far with this, it’s not quite enough. While we can write HTML by hand, in this day and age it’s easier to use template engines to do that for us. Since we are looking for something lightweight, let’s pick Mustache (mustache.github.io).

If this is appearing a tad contrived, that is because it is. If you’re starting a new web project, it makes sense to pick a templating engine at the same time that you choose Spring Web. Nevertheless, this tactic of adding additional modules to existing projects still works.
