title: How to integrate log4j 2 into my Spring project?
body: <p>So I just downloaded Spring Tool Suite, created a new Maven project, and am confused as to how to get Log4j integrated into my project.</p>
  
  <p>Here is my project structure and the class I'm trying to create a logger in.  Please note that none of these imports listed under LoggerFactory work - every time I select one it says <code>LoggerFactory.getLogger cannot be resolved to a type</code>.</p>

  <p>And here is my pom.xml file:</p>
