Due to a break in compatibility in the SLF4J binding, Log4j now ships with two versions of the SLF4J to Log4j adapters.

SLF4J stands for Simple Logging Facade for Java.It provides a simple abstraction of all the logging frameworks in Java. to use log4j in your project, you will have to include below given jar files: slf4j-log4j12-1.7.12.jar; log4j-1.2.17.jar; Once you have places both jar files in your application classpath, SLF4j will automatically detect it and start using log4j for processing the log statements ⦠If SLF4J finds multiple bindings, it will pick one logging framework from the list and bind with it. Browse folder. We use slf4j to log information in the broker client and the broker itself so you can fully configure which logging levels are used and whether to log to files or the console etc. Simply include the Log4j 2 SLF4J Binding jar along with the Log4j 2 jars to cause all SLF4J logging to be handled by Log4j 2.

JCL is, by its intentions, a framework similar to SLF4J. It is not a logging implementation. As can be seen on the last line of the warning, SLF4J has chosen Log4j by using org.slf4j.impl.Log4jLoggerFactory for the actual binding. 3. Currently, parsers in it use either slf4j-api or logging approach from underlying library, e. g. parsers in o.a.tika.parsers.microsoft which use Apache POI depends on Apache Commons Logging and Apache Log4j 1.2.

Use of the Log4j 2 SLF4J Binding (log4j-slf4j-impl-2.0.jar) together with the SLF4J adapter (log4j-to-slf4j-2.0.jar) should never be attempted, as it will cause events to endlessly be routed between SLF4J and Log4j â¦
