Possible discrepancies in pom.xml preventing Spring mappings while launching war on Tomcat 7 - spring

Question

I've been working at this problem for quite some time, and am at a loss.
What baffles me beyond belief is that I once had this configuration working with the pom unaltered which makes me think the issue involves configuration within IntelliJ. I thought that may have been due to using an older version of Tomcat 7, but when I went back to try that version (7.0.92), I had the same result. Currently I am on version 7.0.99.
The issue involves no errors, for some reason the Spring mappings aren't being hit, which were previously all logged within the output in the server log. I've tried many tweaks to the pom to no avail.
Currently the Application class has the #SpringBootApplication annotation.
The pom was written previously (so apologies if a bit unweildy); I'm just working to refactor bits at this point to attempt to get it working.
Any help is greatly appreciated, I've scoured the internet quite thoroughly and have been banging my head against the wall for some time now...
Here is the pom for reference:
