Web App not serving static resources using Spring Boot and Tomcat

Question

Hello I am having troubles 'serving' resources with my web server, while some of my other resources are 'serving.' (graphs.js is loading)

In my browser console:

GET http://localhost:8080/js/app.js [HTTP/1.1 400 Bad Request 2ms]
GET http://localhost:8080/includes/header.html [HTTP/1.1 400 Bad Request 4ms]
GET http://localhost:8080/cs/bootstrap.min.css [HTTP/1.1 400 Bad Request 3ms]

But these files are located in my directory as such:

css/
    bootstrap.min.css
includes/
    header.html
js/
    app.js
    controllers/
        graphs.js

When my server starts:

2014-07-28 08:25:06.748  INFO 5260 --- [           main] .t.TomcatEmbeddedServletContainerFactory : Server initialized with port: 8080

and my HTML is like:

<script type="text/javascript" src="js/app.js"></script>
<script type="text/javascript" src="js/controllers/graphs.js"></script>
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">

You have not stated if you have followed instructions for packaging as a war instead of a JAR and bundling Tomcat in. This does change things a little. Either way, take a look at the documentation here: http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-spring-mvc-static-content

Bascally, out of the box, you can place static content in one of the locations mentioned: /static, /public, /resources or /META-INF/resorces. As for the location of these folders, well either at the root of the servlet context or on the classpath.

You can find a very basic Tomcat application here: https://github.com/mmeany/spring-boot-web-mvc that does the job.
