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.

Swapping hardcoded users with a Spring Data-backed set of users

Creating a hardcoded set of users is great if we’re creating a demo (or writing a book!), but it’s no way to build a real, production-oriented application. Instead, it’s better to outsource user management to an external database.

By having the application reach out and authenticate against an external user source, it makes it possible for another team, such as our security engineering team, to manage the users through a completely different tool that manages that database.

Decoupling user management from user authentication is a great way to improve the security of the system. So, we’ll combine some of the techniques we learned in the previous chapter with the UserDetailsService interface we learned about in the previous section.

Since we already have Spring Data JPA and H2 on the classpath, we can start off by defining a JPA-based UserAcount domain object as follows:

@Entity
