Log4j 2 Logger

You need to also include Log4j 2 dependencies:

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.11.1</version>
</dependency>

And also provide a Log4j 2 configuration file in your classpath. For example, you can add in your src/main/resources project dir a log4j2.properties file like:

appender.console.type = Console
appender.console.name = console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %marker%m%n

rootLogger.level = info
rootLogger.appenderRef.console.ref = console
