Does @Service guarantee uniqueness in Spring?

Question

Assuming a class is annotated with @Service, does Spring guarantee a unique instance of the class for injection? Or should I put @Scope("singleton") on every service?

From the docs

The singleton scope is the default scope in Spring

So there is no need to set this explicitly.
