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.

With a clean definition of roles for controllers, handler mappings, view resolvers, and Plain Old Java Object (POJO) command beans, Spring MVC makes use of all the core Spring features--like dependency injection and autowiring--to make it simple to create web applications. With its support for multiple view technologies, it is extensible too.

While Spring MVC can be used to create REST services, we discuss that in Chapter 5, Building Microservices with Spring Boot.

In this chapter, we will focus on reviewing the basics of Spring MVC with simple examples.

In this chapter will cover the following topics:

  • The Spring MVC architecture
  • The roles played by DispatcherServlet, view resolvers, handler mappings and controllers
  • Model attributes and session attributes
  • Form binding and validation
  • Integration...
