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


An application without data is like a car without fuel. Data is the heart of an application. Some applications may exist in the world without data, but these applications are simply showcase applications such as static blogs. Data is an important part of an application, and you need to develop data-access code for your application. This code should very simple, robust, and customizable.

In a traditional Java application, you could use JDBC to access the data. It is a very basic way, but sometimes, it is very messy to define specifications, handle JDBC exceptions, make database connections, load drivers, and so on. Spring simplifies these things by removing the boilerplate code and simplifying JDBC exception handling. You just write your SQL that should be executed in the application, and the rest is managed by the Spring framework.

In this chapter, you have seen how Spring provides support at the backend for data access and data persistence. JDBC is useful, but using the JDBC API directly...
