            <version>2.14.0</version>
        </dependency>

2. Create log4j2.xml file in the resources folder

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout
                    pattern="[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug" additivity="false">
            <AppenderRef ref="console" />
        </Root>
    </Loggers>
</Configuration>

3. Create logger instances :

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

private static final Logger LOGGER = LogManager.getLogger(ClasName.class.getName());
