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

In this chapter, we will learn one advanced step of accessing database using the Object Relational Mapping (ORM) Framework and managing transactions across the application.

Similarly, when your application has a small set of data for a business tier, then JDBC works fine, but as your application grows and becomes more complex, it becomes difficult to map tables to the objects in the application. JDBC is the dummy small phone of the data access world. But with complex applications, we need Object Relational...
