log4j2 – Failed to load class “org.slf4j.impl.StaticLoggerBinder”

The Java project is using log4j2, but look like some components are used SLF4J logging and caused the following error message:


SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Solution

To fix it, we need a SLF4J Bridge. Puts log4j-slf4j-impl in the classpath.

pom.xml

	<!-- log4j2 -->
	<dependency>
		<groupId>org.apache.logging.log4j</groupId>
		<artifactId>log4j</artifactId>
		<version>2.11.2</version>
	</dependency>

	<!-- SLF4J Bridge -->
	<dependency>
		<groupId>org.apache.logging.log4j</groupId>
		<artifactId>log4j-slf4j-impl</artifactId>
		<version>2.11.2</version>
	</dependency>
