J2EE. Logging in application

Logging is an cross-cutting concern in the application.

It is tedious to write every time

Logger log = LogManager.getLogger(getClass()); 

To speed up one can copy this string from one class to another.
Not very expressive way. Well, it is more code to read.
Nowadays we have annotations, we have EJB, we have CDI.

We can improve the logging code in two ways:

1. implement the logging as a cross-cutting concern with a CDI interceptor
2. if we need more logging it would be much simpler to inject logger
