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.

Common Hibernate traps

The JPA and Hibernate ORM are the most popular frameworks used in most Java applications to interact with a relational database. Their popularity increased because they use the mapping between the object-oriented domain and underlying relational database to abstract the database interactions and make it very easy to implement simple CRUD operations.

Under this abstraction, Hibernate uses a lot of optimizations and hides all database interactions behind its API. Oftentimes, don't even know when Hibernate will execute an SQL statement. Because of this abstraction, it becomes hard to find inefficiencies and potential performance problems. Let's see the common Hibernate problems that we face in our applications.
