Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

Basic flows


Spring MVC uses a modified version of the Model 2 Front Controller architecture. Before we go into details about how Spring MVC works, we will focus on creating a few simple web flows using Spring MVC. In this section, we will create six typical web application flows using Spring MVC. The flows are listed as follows:

  • Flow 1: Controller without a View; serving content on its own
  • Flow 2: Controller with a View (a JSP)
  • Flow 3: Controller with a View and using ModelMap
  • Flow 4: Controller with a View and using ModelAndView
  • Flow 5: Controller for a simple form
  • Flow 6: Controller for a simple form with validation

At the end of every flow, we will discuss how to unit test the Controller.

Basic setup

Before we start with the first flow, we would need to get the application set up to use Spring MVC. In the next section, we will start by understanding how to set up Spring MVC in a web application.

We are using Maven to manage our dependencies. The following steps are involved in setting up a simple...
