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 used start.spring.io to create a barebones web application. We injected some demo data using a service. We create a web controller that uses Mustache to render dynamic content based on the demo data.

Then, we created a JSON-based API allowing third-party apps to interact with our web app, whether it’s to retrieve data or send in updates.

Finally, we leveraged Node.js to introduce some JavaScript to our web app using a Maven plugin.

Building web controllers, serving up templates, rendering JSON-based APIs, and serving up JavaScript apps is a valuable skill on just about any project.

In the next chapter, Querying for Data with Spring Boot, we will dig into creating and managing real data using Spring Data and the amazing power Spring Boot brings us.
