Spring Boot and Security with custom AngularJS Login page

I'm implementing a custom AngularJS login page for Spring Security and having issues authenticating.

Followed this tutorial/example, and their example works fine locally.

However, when I try to implement this myself, authentication fails. I'm not sure where my mistake is.

A POST is made to /login with credentials, (the curl is identical to the example), and I receive a 302 Found with a redirect to GET /login/, which returns a 404 Not Found.

When I try to POST to /login, Spring does not generate any debug logs. So I'm not sure how it is serving the 302.

My code can be found here:

Notable changes (And most likely the source of my issues):

• File structure changes

• Using strictly Angular (No jQuery) - Which results in a different function needed to make the POST request

• Using bower instead of wro4j

• Angular code styling/scoping

Many related Spring Security questions suggest the POST request is formatted incorrectly, but mine appears to be the same as the example (at least when I copy to curl in chrome dev console). Others suggest implementing custom authorization providers, but it is not needed in the example, so I'm perplexed to what the difference is between mine and the example. Help me Stack Exchange, you're my only hope.
