Cannot get .debug() messages to show up for slf4j in Java

I can't get this to work. I've also tried the --debug option in IntelliJ. It's always printing "debug is not enabled" and never printing my .debug() messages to console. Any ideas?

the .java file

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MyClass {
    private final Logger logger = LoggerFactory.getLogger(MyClass.class);

    public void myMethod() {
        if (logger.isDebugEnabled()) {
            logger.info("debug is enabled");
        }
        else {
            logger.info("debug is not enabled");
        }
        logger.debug("\n\ntest debug message\n\n");
    }

src/main/resources/log4j.properties

log4j.rootLogger=debug, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.logger.com.mycompany=debug

I tried updating my application.yml to set the logging level but it had no effect:

application.yml

  logging:
    level:
      root: DEBUG
      org.springframework.web: DEBUG
      guru.springframework.controllers: DEBUG
      org.hibernate: DEBUG

I figured it out. After poking around SO more, I updated my config file to set the logging level as follows:

/src/main/resources/application.yml

logging:
  level:
    ROOT: DEBUG

(note: indent level matters! It would only work when it was at the very top level of the .yml file, i.e. no indents)
