If it is a class, it does not need to be bound through ServiceProvider, and the class will be automatically injected. But if it is an interface, laravel's container needs to know which implementation is, so you need to bind the interface and the implemented class through ServiceProvider. You can try it. if it is not bound, if you inject an interface into the controller, an error will be reported.
