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.

Authentication cache

Spring Security performance becomes one of the major concerns when there is a maximum number of calls hit on the application. By default, Spring Security creates a new session for each new request and prepares a new security context every single time. This becomes an overhead when maintaining user authentication, and due to that, performance is lowered.

For example, we have an API that requires authentication on each request. If there are multiple calls made to this API, it will impact the performance of the application which uses this API. So, let's understand this problem without a caching implementation. Take a look at the following logs, where we call an API using the curl command, without a caching implementation:

curl -sL --connect-timeout 1 -i http://localhost:8080/authentication-cache/secure/login -H "Authorization: Basic Y3VzdDAwMTpUZXN0QDEyMw...
