If I understand your use case, most loggers (like Logback) have the possiblity to automatically include the name of the method that called the log-statement.

Logback even supports including the call chain in the output, so you could include the parent method, grand parent method etc. This probably uses reflection, so it could have a negative impact for applications that need a high performance.
