Building Applications with Spring 5 and Kotlin

Learn to build a full-fledged application in Spring and Kotlin taking a reactive, microservice-based approach for scalability and robustness in the cloudAbout This BookBuild a full-fledged application in Spring and KotlinArchitect your application to take a microservice-based approach in the cloudIntegrate your application with a variety of Spring componentsWho This Book Is ForDevelopers comfortable using Spring who have basic knowledge of Kotlin and want to take their development skills to the next level and build enterprise-grade applications will benefit from this book.What You Will LearnExplore Spring 5 concepts with KotlinLearn both dependency injections and complex configurationsUtilize Spring Data, Spring Cloud, and Spring Security in your applicationsCreate efficient reactive systems with Project ReactorWrite unit tests for your Spring/Kotlin applicationsDeploy applications on cloud platforms like AWSIn DetailKotlin is being used widely by developers because of its light weight, built-in null safety, and functional and reactive programming aspects. Kotlin shares the same pragmatic, innovative and opinionated mindset as Spring, so they work well together. Spring when combined with Kotlin helps you to reach a new level of productivity. This combination has helped developers to create Functional Applications using both the tools together. This book will teach you how to take advantage of these developments and build robust, scalable and reactive applications with ease.In this book, you will begin with an introduction to Spring and its setup with Kotlin. You will then dive into assessing the design considerations of your application. Then you will learn to use Spring (with Spring Boot) along with Kotlin to build a robust backend in a microservice architecture with a REST based collaboration, and leverage Project Reactor in your application. You'll then learn how to integrate Spring Data and Spring Cloud to manage configurations for database interaction and cloud deployment. You'll also learn to use Spring Security to beef up security of your application before testing it with the JUnit framework and then deploying it on a cloud platform like AWS.Style and approachEverything you learn will be demonstrated on real-world Spring project. In each chapter we will cover some of Spring features and apply it on our project. We will guide you from the project initialization till the project deployment.
