Who This Book Is For

If you're a developer starting out with Spring, then this book will help you learn about the new Spring 5.0 framework concepts followed by their implementation in Java and Kotlin. The book will also help experienced Spring developers gain insights into the new features added in Spring 5.0.

What You Will Learn

• Implement REST APIs with Spring REST support
• Introduce the Spring Boot and understand how it makes creating robust applications extremely simple
• Understand how Spring Data helps us add persistence in MongoDB and SQL databases
• Introduce Reactive Programming and use this with Spring Webflux
• Implement a Reactive REST client and learn how it can create asynchronous applications
• Create a robust, scalable, and fault tolerant application with Spring Messaging
• Implement a websocket to add interactive behaviors in your applications
• Introduce the Spring Cloud projects

In Detail

With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring.

The book has three parts, where each one covers the building of a comprehensive project in Java and Spring. In the first part, you will construct a CMS Portal using Spring's support for building REST APIs. You will also learn to integrate these APIs with AngularJS and later develop this application in a reactive fashion using Project Reactor, Spring WebFlux, and Spring Data. In the second part, you'll understand how to build a messaging application, which will consume the Twitter API and perform filtering and transformations. Here, you will also learn about server-sent events and explore Spring's support for Kotlin, which makes application development quick and efficient. In the last part, you will build a real microservice application using the most important techniques and patterns such as service discovery, circuit breakers, security, data streams, monitoring, and a lot more from this architectural style.

By the end of the book, you will be confident about using Spring to build your applications.

Style and approach

This book teaches you to use the new version of Spring Framework to solve problems commonly encountered in modern web application; it explains the main features of this version such as support for Reactive programming and Kotlin. You'll learn these features by creating interesting projects and putting them into practice right now.
