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

Data binding with Command Design pattern


Encapsulate a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undoable operations. - GOF Design Pattern

You learned about the Command Design pattern in Chapter 3, Consideration of Structural and Behavioral Patterns. It is a part of the Behavioral pattern family of the GOF pattern. It is a very simple data-driven pattern. It allows you to encapsulate your request data into an object, and pass that object as a command to the invoker method, and that method returns the command as another object to the caller.

Spring MVC implements the Command Design pattern to bind the request data from the web form as an Object, and passes that object to the request handler method in the controller class. Here, we will explore how to use this pattern to bind the request data to the Object, and also explore the benefits and possibilities of using data binding. In the following class, the Account...
