Tomcat8 Springboot not reading application.properties

I'm working with java spring for the first time on a personal project and I can't seem to get any of the properties in application.properties to work correctly. I've simplified it down to this test case and it doesn't seem to be doing anything:

application.properties

logging.level.root=WARN

AppInitalizer.java:

import javax.servlet.Filter;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


@SpringBootApplication
@ConfigurationProperties
public class AppInitializer
    extends AbstractAnnotationConfigDispatcherServletInitializer {

    private static final Logger log = LoggerFactory.getLogger(AppInitializer.class);

    @Override
    protected Class<?>[] getRootConfigClasses() {
        log.debug("This is a debug message");
        log.error("This is an error message");
        return new Class[] {};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] {};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Filter[] getServletFilters() {
        return new Filter[] {};
    }
}

Log after deploy:

20:08:26.113 [http-nio-8080-exec-32] DEBUG AppInitializer - This is a debug message
20:08:26.114 [http-nio-8080-exec-32] ERROR AppInitializer - This is an error message

The two files are deployed to the same directory at the root of the classpath.

Only the second log message should be showing but I can't take care of the first.

Relevant ivy.xml config:

<!-- Spring Framework -->
<dependency org="org.springframework"
            name="spring-webmvc" rev="5.0.9.RELEASE"/>
<!-- Logging -->
<dependency org="log4j" name="log4j" rev="1.2.17"/>

Edit: I switched out my logger to slf4j and still not luck.

Edit2: Added dependencies

Edit3: I was looking through he log and found this:

None of the property sources seem to be loading from the classpath which is where I have the application.properties.

Use slf4j's LoggerFactory instead of org.apache.commons.logging.LogFactory:

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

private final Logger log = LoggerFactory.getLogger(this.getClass());

Or static logger:

private static final Logger log = LoggerFactory.getLogger(AppInitializer.class);

Please use slf4j.Logger over apache.commons.logging

  1. Spring has also introduces the new @PropertySource annotation, as a convenient mechanism for adding property sources to the environment. This annotation is to be used in conjunction with Java based configuration and the @Configuration annotation:

    @Configuration @PropertySource("classpath:foo.properties") public class AppInitializer{ //... }

  2. One other very useful way of registering a new properties file is using a placeholder to allow you to dynamically select the right file at runtime; for example:

    @PropertySource({ "classpath:persistence-${envTarget:mysql}.properties" })

  3. You can use in XML, new properties files can be made accessible to Spring via the namespace element:

The foo.properties file should be placed under /src/main/resources so that it will be available on the classpath at runtime.
