Spring 5 Design Patterns

By: Dinesh Rajput

Overview of this book

Design patterns help speed up the development process by offering well tested and proven solutions to common problems. These patterns coupled with the Spring framework offer tremendous improvements in the development process. The book begins with an overview of Spring Framework 5.0 and design patterns. You will understand the Dependency Injection pattern, which is the main principle behind the decoupling process that Spring performs, thus making it easier to manage your code. You will learn how GoF patterns can be used in Application Design. You will then learn to use Proxy patterns in Aspect Oriented Programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. Then, you will be introduced to MVC patterns to build Reactive web applications. Finally, you will move on to more advanced topics such as Reactive streams and Concurrency. At the end of this book, you will be well equipped to develop efficient enterprise applications using Spring 5 with common design patterns

Summary


In this chapter, you learned about the Reactive pattern and its principles. It is not a new innovation in programming--it is a very old concept, but it very fits in very well with the demands of modern applications.

Reactive programming has four principles: responsiveness, resilience, elasticity, and message-driven architecture. Responsiveness means a system must be responsive in all conditions: odd conditions and even conditions.

The Spring 5 Framework provides support for the reactive programming model by using the Reactor framework and reactive stream. Spring has introduced new a reactive web module, that is, spring-web-reactive. It provides the reactive programming approach to a web application by either using Spring MVC's annotations, such as @Controller, @RestController, and @RequestMapping, or by using the functional programming approach using the Java 8 Lambda expression.

In this chapter, we created a web application by using the spring web reactive modules. The code for this...
