I was trying to do the same and got this solution. 1. Create connectionFactory.java file

import java.sql.Connection;
import java.sql.SQLException;
import java.util.Properties;

import javax.sql.DataSource;

import org.apache.commons.dbcp.DriverManagerConnectionFactory;
import org.apache.commons.dbcp.PoolableConnectionFactory;
import org.apache.commons.dbcp.PoolingDataSource;
import org.apache.commons.pool.impl.GenericObjectPool;

public class ConnectionFactory {

    private static interface Singleton {
        final ConnectionFactory INSTANCE = new ConnectionFactory();
    }
    private final DataSource dataSource;

    private ConnectionFactory() {
        Properties properties = new Properties();
        properties.setProperty("user", "aabsUser");
        properties.setProperty("password", "aj12fk18");

        GenericObjectPool pool = new GenericObjectPool();
        DriverManagerConnectionFactory connectionFactory = new DriverManagerConnectionFactory(
                "jdbc:mysql://localhost:3306/aabs", properties);
        new PoolableConnectionFactory(connectionFactory, pool, null,
                "SELECT 1", 3, false, false,
                Connection.TRANSACTION_READ_COMMITTED);

        this.dataSource = new PoolingDataSource(pool);
    }

    public static Connection getDatabaseConnection() throws SQLException {
        return Singleton.INSTANCE.dataSource.getConnection();
    }
}

2. make Entries in Log4j2.properties

name=PropertiesConfig
appenders=db
appender.db.type = Jdbc
appender.db.name = MySQLDatabase

# replace databaseName.tableName
appender.db.tableName =databaseName.tableName
appender.db.cf.type = ConnectionFactory

# change class path and method name
appender.db.cf.class = com.log4j2demo.ConnectionFactory
appender.db.cf.method = getDatabaseConnection
# define column type, column name and value
appender.db.col2.type = Column
appender.db.col2.name = DATE
appender.db.col2.isEventTimestamp = true

appender.db.col3.type = Column
appender.db.col3.name = LOG_LEVEL
appender.db.col3.pattern = %p

appender.db.col4.type = Column
appender.db.col4.name = FILE
appender.db.col4.pattern = %F

#Initialize logger
loggers=db
logger.db.name=com.log4j2demo.Demo
logger.db.level = All
logger.db.appenderRefs.db.ref = MySQLDatabase

#Initialize rootLogger
rootLogger.level =info
rootLogger.appenderRefs = db
rootLogger.appenderRef.db.ref = MySQLDatabase

3. Implement Logger

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

public class Demo {

    private static Logger log = LogManager.getLogger();

    public static void main(String[] args) throws InterruptedException {
        log.trace("Entering application.");
        log.trace("Trace.");
        for (int i = 0; i < 10; i++) {
            log.info("Testing Lof For DB");
        }
        log.debug("Debug.");
        log.fatal("Fatal.");
        log.log(Level.WARN, "Warn");
        int a, b, c;
        a = 1;
        b = 0;
        try {
            c = a / b;
            log.info("vale of c" + c);
        } catch (Exception e) {
            log.error("error occur>>" + e);
        }
    }

}
