Overview of this book

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 course is up made of three modules, each one having a take-away relating to building end-to-end java applications. The first module takes the approach of learning Spring frameworks by building applications.You will learn to build APIs and integrate them with popular fraemworks suh as AngularJS, Spring WebFlux, and Spring Data. You will also learn to build microservices using Spring's support for Kotlin. You will learn about the Reactive paradigm in the Spring architecture using Project Reactor. In the second module, after getting hands-on with Spring, you will learn about the most popular tool in the Spring ecosystem-Spring Boot. You will learn to build applications with Spring Boot, bundle them, and deploy them on the cloud. After learning to build applications with Spring Boot, you will be able to use various tests that are an important part of application development. We also cover the important developer tools such as AMQP messaging, websockets, security, and more. This will give you a good functional understanding of scalable development in the Spring ecosystem with Spring Boot. In the third and final module, you will tackle the most important challenges in Java application development with Spring Boot using practical recipes. Including recipes for testing, deployment, monitoring, and securing your applications. This module will also address the functional and technical requirements for building enterprise applications. By the end of the course you will be comfortable with using Spring and Spring Boot to develop Java applications and will have mastered the intricacies of production-grade applications.

Learning Kotlin basics

The Kotlin language was released officially in February 2016. JetBrains created it and has been developing the language ever since. The company is the owner of the IntelliJ IDEA IDE. 

In February 2012, JetBrains made the language open source under the Apache v2 license; the license allows developers to create applications.

The language is one option for JVM(Java Virtual Machine) languages such as Clojure and Scala, which means that the language can compile bytecode for JVM. As we will see, Kotlin has many similarities with Scala. Kotlin has the Scala language as a reference, but the JetBrains teams believe that Scala has problems with the compilation time.

Kotlin was becoming an adopted language in the Android world and because of this, in the Google I/O, 2017, the Google Team announced official support for the Android ecosystem. Since then, the language has been growing year by year and increasing in popularity.
