Java EE 8 Design Patterns and Best Practices

By: Rhuan Rocha, Joao Carlos Purificação

Overview of this book

Patterns are essential design tools for Java developers. Java EE Design Patterns and Best Practices helps developers attain better code quality and progress to higher levels of architectural creativity by examining the purpose of each available pattern and demonstrating its implementation with various code examples. This book will take you through a number of patterns and their Java EE-specific implementations. In the beginning, you will learn the foundation for, and importance of, design patterns in Java EE, and then will move on to implement various patterns on the presentation tier, business tier, and integration tier. Further, you will explore the patterns involved in Aspect-Oriented Programming (AOP) and take a closer look at reactive patterns. Moving on, you will be introduced to modern architectural patterns involved in composing microservices and cloud-native applications. You will get acquainted with security patterns and operational patterns involved in scaling and monitoring, along with some patterns involved in deployment. By the end of the book, you will be able to efficiently address common problems faced when developing applications and will be comfortable working on scalable and maintainable projects of any size.

Explaining the concept of continuous deployment


The process of delivery release to users consists of important steps, and we can sometimes pass these steps with a manual process. The world is moving on apace, and so the delivery of a release needs to be swift as well. With this in mind, automating processes is a great solution for increasing the speed of release delivery; continuous deployment was therefore created as an evolution of continuous delivery, which itself is an evolution of continuous integration. 

Continuous deployment is a deployment pattern that creates a pipeline where each step is executed through an automated process. All steps are then executed without human intervention. If a new release enters the pipeline, all steps will be executed automatically unless an error occurs. It is important to know that continuous deployment is not continuous delivery or continuous integration—although these deployment patterns have many similarities, they are all different. The main difference...
