In the previous chapter, we learned how Spring Framework implements the Inversion of Control (IoC) principle. Spring IoC is the mechanism to achieve loose coupling between object dependencies. A Spring IoC container is the program that injects dependencies into an object and makes it ready for our use. Spring IoC is also known as dependency injection. In Spring, the objects of your application are managed by the Spring IoC container and are also known as beans. A bean is an object that is instantiated, assembled, and managed by a Spring IoC container. So, a Spring container is responsible for creating the beans in your application and coordinating the relationships between those objects via dependency injection. But, it is the developer's responsibility to tell Spring which beans to create and how to configure them together...

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.
