How to serve an html file with .html url extension using Spring

Question

I'm trying to use the Application Security on Cloud provided by Bluemix for a Spring application.

I'm relatively new to Spring and I'm having difficulty serving the requested verification file with the requested url. Bluemix wants the html file to be available at /IBMDomainVerification.html

However, I can't figure out how to serve the html file given that exact url using Spring. I can serve it without the .html at the end of the url but that's not what it needs.

If anyone can let me know how I can serve the html file given the specified url with the .html extension on the end that'd be great!

Thanks!

Spring 4.1 introduced the ResourceResolvers, that can resolve resources, given their URL path. In particular you could use the simplest: PathResourceResolver. This is the simplest resolver and its purpose is to find a resource given a public URL pattern. In fact, if no ResourceResolver is added to the ResourceChainRegistration, this is the default resolver.

Consider the following example:

@Override 
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
  .addResourceHandler("/resources/**")
  .addResourceLocations("/resources/","/other-resources/")
  .setCachePeriod(3600)
  .resourceChain(true)
  .addResolver(new PathResourceResolver());
}

The above code serves anything in either the webapp/resources of the webapp/other-resources folder, required with URLs /resources/** (e.g. /resources/foo.js). Note the two asterisks, it means that it will match everything after resources/, even '/'.

In your case using /IBMDomainVerification.html (/**) it should work.

An alternative way could be using *<mvc:resources/>* (Spring 3) which can be used to serve static resources while still using the DispatchServlet on root. Please refer to this SO answer.
