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.

Hibernate programming practices

Until now, we saw problems with Hibernate when it is not used optimally, and how to use Hibernate to achieve better performance. The following are the best practices to follow (in terms of caching, and in general) to achieve better performance when using JPA and Hibernate.


The following are some programming tips in relation to the different caching levels in Hibernate:

  • Make sure to use the same version of hibernate-ehcache as the version of Hibernate.
  • Since Hibernate caches all of the objects into the session first level cache, when running bulk queries or batch updates, it's necessary to clear the cache at certain intervals to avoid memory issues.
  • When caching an entity using...
