Spring Framework Master Class - Java Spring the Modern Way - Step 09 - Creating Custom Annotation and an Aspect for Trac

The video tutorial explains how to implement performance tracking using around advice in Spring AOP. It covers creating a custom annotation, @TrackTime, to track method execution time selectively. The tutorial details defining a retention policy for runtime availability and using annotations to define point cuts. It demonstrates tracking execution time for specific methods and concludes with a summary of the concepts learned, emphasizing the fun and utility of AOP.
