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

Configuring the data source and object pool pattern


In the Spring Framework, DataSource is part of the JDBC API, and it provides a connection to the database. It hides many boilerplate codes for connection pooling, exception handling, and transaction management issues from the application code. As a developer, you let it focus on your business logic only. Don't worry about connection pooling, exception handling, and managing transactions; it is the responsibility of the application administrators how they set up the container managed data source in production. You just write the code, and test that code.

In an enterprise application, we can retrieve DataSource in several ways. We can use the JDBC driver to retrieve DataSource, but it is not the best approach to create DataSource in the production environment. As performance is one of the key issues during application development, Spring implements the object pool pattern to provide DataSource to the application in a very efficient way. The...
