Application Structure & Service Layer
Clarification
At a certain point in the video it is mentioned that the @Service annotation is optional but recommended for documentation purposes. However, it does actually make a difference when you are using the @Autowire. Spring might not be able to automatically find and inject the Service class if the @Service annotation is missing. So in short: you should use it!
