Hands-On High Performance with Spring 5

By: Chintan Mehta, Subhash Shah, Pritesh 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 task execution and scheduling

Using threads in any web application is not easy when we are dealing with a long-running task. Sometimes, we need to run a task asynchronously or after a specific delay, and that can be accomplished by Spring's task execution and scheduling. The Spring Framework introduced abstractions for asynchronous execution and scheduling of tasks with the TaskExecutor and TaskScheduler interfaces.


Spring provides the TaskExecutor interface as an abstraction for dealing with Executor. The implementation classes of TaskExecutor are as follows:

  • SimpleAsyncTaskExecutor: This starts a new thread and executes it asynchronously. It does not reuse the thread.
  • SyncTaskExecutor: This executes...
