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

Dependency injection pattern with Annotation-based configuration


As discussed in the previous two sections, we defined the DI pattern with Java-and XML-based configurations, and these two options define dependencies explicitly. It creates the Spring beans by using either the @Bean annotated method in the AppConfig Java file, or the <bean> element tag in the XML configuration file. By these methods, you can also create the bean for those classes which lie outside the application, that is, classes that exist in third-party libraries. Now let's discuss another way to create Spring beans, and define the dependencies between them by using implicit configuration through the Stereotype annotations.

What are Stereotype annotations?

The Spring Framework provides you with some special annotations. These annotations are used to create Spring beans automatically in the application context. The main stereotype annotation is @Component. By using this annotation, Spring provides more Stereotype meta...
