Java EE 8 High Performance

By: Romain Manni-Bucau

Overview of this book

The ease with which we write applications has been increasing, but with this comes the need to address their performance. A balancing act between easily implementing complex applications and keeping their performance optimal is a present-day need. In this book, we explore how to achieve this crucial balance while developing and deploying applications with Java EE 8. The book starts by analyzing various Java EE specifications to identify those potentially affecting performance adversely. Then, we move on to monitoring techniques that enable us to identify performance bottlenecks and optimize performance metrics. Next, we look at techniques that help us achieve high performance: memory optimization, concurrency, multi-threading, scaling, and caching. We also look at fault tolerance solutions and the importance of logging. Lastly, you will learn to benchmark your application and also implement solutions for continuous performance evaluation. By the end of the book, you will have gained insights into various techniques and solutions that will help create high-performance applications in the Java EE 8 environment.

JCache – the standard cache of Java EE

JCache was added to Java EE to enable the application and libraries to interact in a standard manner with the caching. Therefore, it has two types of APIs and features:

  • A programmatic Cache API to write/read data
  • A CDI integration to automatically put data in the cache

Setting up JCache

To use JCache, you may need to add it to your application—or to your server, depending on how you want to deploy itsince not all servers add it in their distribution(s). To do it with maven, you can add this dependency:
