Why add this empty line? Is it caused by the formater?

It is recommended to upgrade to 2.17.1, which fixes all known vulnerabilities, see: https://logging.apache.org/log4j/2.x/security.html.

The original code is simpler and the performance is the same.

What problem does this PR solve?
Issue Number: close #396
Problem Description: this pull request upgrade the log4j and slf4j to avoid some security issues and improve the performance while a higher log level is set. In addition, this pull request eliminates the code of log level detections which is really annoying. For now, this pull request only focuses on the DEBUG log, instead of the higher-level logs.
What is changed and how it works?
Use slf4j 2.0's fluent API to eliminate the log level check and use lambda syntax to enable lazy log string evaluation.
