Dynamic proxy is a powerful concept in Java and Spring that allows for the creation of proxy objects at runtime rather than compile-time. In Spring, dynamic proxies are used extensively for implementing cross-cutting concerns like transaction management, security, logging, and more, without polluting the business logic. This article will provide a detailed explanation of dynamic proxies in Spring, how they work, and how you can implement and use them effectively. We'll also explore real-world examples, demos, and the expected outcomes of those demos.
