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 deployment patterns


Applications constantly receive updates that function to create new features or correct any problems. These new features and updates need to be promoted to a production-level without causing any problems or delays to a service. Furthermore, it is sometimes necessary to deliver a new version of an application to a select group of users, such as those in certain countries or certain business areas. 

When we talk about delivery in this context, we are referring to releasing a new version of an application into the production environment. A software project has various steps that need to be evaluated and considered in order to permit the delivery of good software.

These steps include following a good process to get the business role, a good process for testing the application, a good process for developing the code of the application, and a good process for delivering the project to production, which is the aim of the project. All software projects...
