This book will teach you how to use the Spring Framework to build Java-based applications, web applications, and microservices. Aimed at beginners, it has been revised and expanded to reflect the latest features and best practices for Spring 6.

Authors Joseph Ottinger and Andrew Lombardi will get you started using Spring Framework 6 and its ecosystem, walking you through all the best practices in modern application development. You’ll see how Spring has drastically and positively affected the way applications are designed and programmed in Java, and how to build apps with the Spring mindset. Along the way, you will learn many aspects of the Spring ecosystem with easy-to-understand applications designed to teach you not only the technology, but also the practices that benefit the most from Spring. Starting with the basics, you’ll learn gradually, including topics such as the configuration and declaration of beans, the application lifecycle, how to deploy a Spring application into a Java EE application, Spring Reactive, Spring Web, Spring Boot, and Spring Cloud.

After completing this book, you’ll be prepared to develop your own scalable, modular Spring-based applications.

You will:

Discover the most common use cases encountered in the real world

Learn the proper way of testing with the Spring framework

Create reliable, modular software

Build skills that will translate well across all languages and environments

Integrate and use data access and persistence frameworks such as Hibernate, JPA, and MongoDB
