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

Enabling caching via the Proxy pattern


You can enable Spring's cache abstraction in the following two ways:

  • Using Annotation
  • Using the XML namespace

Spring transparently applies caching to the methods of Spring beans by using AOP. Spring applies proxy around the Spring beans where you declare the methods that need to be cached. This proxy adds the dynamic behavior of caching to the Spring beans. The following diagram illustrates the caching behavior:

In the preceding diagram, you can see that Spring applies Proxy to the AccountServiceImpl class to add the caching behavior. Spring uses the GoF proxy pattern to implement caching in the application.

Let's look at how to enable this feature in a Spring application.

Enabling the caching proxy using Annotation

As you already know, Spring provides lots of features, but they are, mostly, disabled. You must enable these feature before using it. If you want to use Spring's cache abstraction in your application, you have to enable this feature. If you are...
