Demoonstrate that changing the servlet context path via Spring Boot works.

When applying server.servlet.context-path=/ctx, the links automatically adjust.

If the issue is closed due to no feedback from issuer / others, should we close / merge this one?

Hi,

I've notice that this does not work correctly if you are using DeferredResult<T> and generating the HATEOAS link on another thread. It looks like it uses ThreadLocals requestAttributesHolder and inheritableRequestAttributesHolder in

org.springframework.web.context.request.RequestContextHolder#getRequestAttributes

called from

org.springframework.web.servlet.support.ServletUriComponentsBuilder#getCurrentRequest

If those ThreadLocals are not set, it drops the context path in the link that's generated.

I found this issue from spring-projects/spring-hateoas#1268 which has been closed now.
