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.

Java threads best programming practices

The purpose of using multithreading and concurrent programming is to improve performance, but we need to always remember that speed comes after correctness. The Java programming language provides lots of synchronization and concurrency support from the language to API level, but it depends on an individual's expertise in writing bug-free Java concurrency code. The following are Java concurrency and multithreading best practices, which help us write better concurrency code in Java:

  • Use immutable classes: We should always prefer the immutable class in multithreading programming because immutable classes make sure that values are not changed in the middle of an operation without using synchronized blocks. For example, in an immutable class, such as java.lang.String, any modification on String, such as adding something or converting into...
