Hands-On High Performance with Spring 5

By: Mehta, Subhash Shah, Shah, Prashant Goswami, Dinesh Radadiya

Overview of this book

While writing an application, performance is paramount. Performance tuning for real-world applications often involves activities geared toward detecting bottlenecks. The recent release of Spring 5.0 brings major advancements in the rich API provided by the Spring framework, which means developers need to master its tools and techniques to achieve high performance applications. Hands-On High Performance with Spring 5 begins with the Spring framework's core features, exploring the integration of different Spring projects. It proceeds to evaluate various Spring specifications to identify those adversely affecting performance. You will learn about bean wiring configurations, aspect-oriented programming, database interaction, and Hibernate to focus on the metrics that help identify performance bottlenecks. You will also look at application monitoring, performance optimization, JVM internals, and garbage collection optimization. Lastly, the book will show you how to leverage the microservice architecture to build a high performance and resilient application. By the end of the book, you will have gained an insight into various techniques and solutions to build and troubleshoot high performance Spring-based applications.

Spring asynchronous processing, @Async annotation

Spring provides support for asynchronous method execution. This can also be achieved using threads, but it makes the code more complex and sometimes results in more bugs and errors. When we need to execute a simple action in an asynchronous manner, it is a cumbersome process to handle it using threads. There are cases in which it is necessary to perform the operation asynchronously, like sending a message from one machine to another machine. The main advantage of asynchronous processing is that the caller will not have to wait for the completion of the called method. In order to execute a method in a separate thread, you need to annotate the method with the @Async annotation.

Asynchronous processing support can be enabled by using the @EnableAsync annotation to run the @Async methods in the background thread pool. The following...
