Now, we'll create our first application; at this point, we have learned the Spring concepts, and we are ready to put them into practice. At the beginning of this chapter, we'll introduce the Spring dependencies to create a web application, also we know that Spring Initializr is a fantastic project that enables developers to create Spring skeleton projects, with as many dependencies as they want. In this chapter, we will learn how to put up our first Spring application on IDE and command line, expose our first endpoint, understand how this works under the hood, and get to know the main annotations of Spring REST support.

Overview of this book
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.
