What is the best way to initialize a registrar in a class?

Question

I have two options for initializing Loggerinside the class.

The first way is to provide an instance Class<?>:

logger = LoggerFactory.getLogger(SignUpController.class);

and the second passes the identifier String(package and class name):

logger = LoggerFactory.getLogger("controller.SignUpController");
