Can anyone explain Autowiring in Spring ?

Say I have a service class called UserServiceImpl that implements UserService interface.

How would this be @Autowired?

And in my Controllers, how would I instantiate an instance of this service?

Would I just do the following?

UserService userService = new UserServiceImpl();
