Implement Cross-Cutting Concerns Using AspectJ Annotations
Explore how to implement cross-cutting concerns in Spring applications using AspectJ annotations. Learn to create custom annotations and aspects to log method execution details and execution time, enhancing modularity and maintainability of your REST API.
