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

Leader/follower pattern


Detection, demultiplexing, dispatching, and processing of service requests in the event sources is carried out in an efficient way in a concurrency model, in which many multiple threads process one by one to use the set on event sources. Another replacement for the Half-Sync/Half-Async is the leader/follower pattern. This pattern can be used instead of the Half-Sync/Half-Async and active object patterns for improvement in the performance. The condition of using this is that there must be neither ordering nor synchronization constraints while processing multiple threads of requests:

The focused job of this pattern is to process multiple events concurrently or simultaneously. Due to concurrency-related overheads, it might not be possible to connect a separate thread with each single socket handle. The highlighted feature of this design is that by using this pattern, demultiplexing the associations between threads and event source becomes possible. When the events arrive...
