Spring (with Jade) Resources

Question

The Problem

My spring-boot application recently changed routing from host/endpoint to host/middle/endpoint. Since the change, I am running into an issue where the resources are not being found relative to the new url structure. Before, I could reference resources like css stylesheets like link(rel='stylesheet', href='css/style.css'), but now the logger shows an error saying it can't find the resource at /middleman/css/style.css.

From my research, I have found that what I need to do is use a resource handler registry. I have created one (as shown below) but it doesn't seem to be working. I think the problem is that even though I now have the resource registry, I am not referencing resources in the registry. What is the proper way to solve this problem and have all resources point load from the same place regardless of the endpoint? I very well may be missing some obvious piece of SOP

If you are using spring boot, you don't need to worry about the resource configuration since you are already configuring the resource directory through the auto configuration. The default behavior for the autoconfiguration is to look within resources/static.

Your issue is with your href values, try inserting a leading forward slash:

link(rel='icon', href='/images/favicon.ico')
link(rel='stylesheet', href='/css/style.css')  
script(src='javascripts/layout.js')
link(rel='stylesheet', href='/css/footer.css')

Spring is routing your application to a new relative path, so by putting the leading / in your href attributes, you are telling the router to look absolutely within the static directory instead of relatively from the middle directory.
