@RequestMapping should support alternative between a header and a url extension [SPR-7722]

[spring-projects-issues]

Stefan Schmidt opened SPR-7722 and commented

It would be nice if we can support request mappings in MVC controllers which kicks in if either a header is present (ie headers = "Accept=application/json") or a URL extension is used (ie /owners/1.json). While this scenario is currently possible with the ContentNegotiatingViewResolver it is not possible to configure the same effect through @RequestMapping in conjunction with @ResponseBody.

From a Spring Roo perspective this would be a nice feature to have. I was thinking if I could define a SPEL expression in some way in the @RequestMapping annotation that would be nice.

There are two other SPR tickets which are related to this: #11163 and #12012

Although 3.1 already has a "produces" condition in @RequestMapping, currently it works off the 'Accept' header only. A more comprehensive update in this area is planned for 3.2 (see #13057).
