Chapter 1, Evolution to Spring Framework 5.0, takes you through the evolution of the Spring Framework, ranging from its initial versions to Spring 5.0. Initially, Spring was used to develop testable applications using dependency injection and core modules. Recent Spring Projects, such as Spring Boot, Spring Cloud, Spring Cloud Data Flow--deal with application infrastructure and moving applications to Cloud. We get an overview of different Spring modules and projects.
Chapter 2, Dependency Injection, dives deep into dependency injection. We will look at different kinds of dependency injection methods available in Spring, and how auto-wiring makes your life easy. We will also take a quick look into unit testing.
