java logging components (common-logging, slf4j, log4j and logbak)

Found a relatively good blog post:

Make a record. Supplementary note:
1. slf4j-over-log4j bridge from log4j to slf4j :
For example, kafka's jar package implements logging based on log4j. How to use it in the logback log application requires slf4j-over-log4j. If log4j is used, two log instance errors will occur. Other logging frameworks are similar.
