ResourceHttpRequestHandler does not take into account mime types configured in WebMvcConfigurerAdapter [SPR-13658]

[spring-projects-issues]

Tom Adam opened SPR-13658 and commented

getMediaType method in ResourceHttpRequestHandler does not take into account the media types registered by a WebMvcConfigurerAdapter instance's configureContentNegotiation method. The method only checks mime types registered in the servlet context of JAF. This way it is impossible to register special media types for static resources except for using web.xml.

Indeed we should be doing more to connect the dots there.

The ResourceHttpRequestHandler now supports a ContentNegotiationManager property, which the MVC java config and the MVC namespace will configure that to be the shared negotiation manager.
