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, we have seen the Spring AOP Framework and used design patterns behind this module. AOP is a very powerful paradigm and it complements the Object oriented programming. Aspect-Oriented Programming (AOP) modularizes cross-cutting concerns such as Logging, Security and Transaction. An aspect is a Java class annotated with @Aspect annotation. It defines a module containing the crosscutting behavior. This module separates from the application's business logic. We can reuse it in our application with other business modules without making any changes.

In Spring AOP, behavior is implemented as an advice method. You have learned in Spring, there are five types as Before, AfterThrowing, AfterReturning, After and Around. Around advice is a very powerful advice, there are interesting features implemented by using Around advice. You've learned how to weave these advices using load time weaving.

You have seen how to declare Pointcuts in the Spring application and pointcuts select...
