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

如果您使用的是spring boot，则无需担心资源配置，因为您已经通过自动配置配置了资源目录。自动配置的默认行为是在resources/static.

您的问题在于您的 href 值，请尝试插入前导正斜杠：

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 正在将您的应用程序路由到一个新的相对路径，因此通过在您的属性中放置前导href，您告诉路由器绝对在static目录中查找，而不是相对地从middle目录中查找。
