Misleading error message in HandlerMethodInvoker.resolveRequestBody() [SPR-5767]

[spring-projects-issues]

Kenny MacLeod opened SPR-5767 and commented

Line 450 of HandlerMethodInvoker.resolveRequestBody throws the exception "Cannot extract response" when it fails to find a content type in the inbound request.

As well as the message itself being confusing, is the check itself really necessary? If there are HttpMessageConverters present that do not care about the content type, should the framework be enforcing it?

I fixed the error message, but the Content-Type is still required for @RequestBody annotations.

For scenarios where a Content-Type is not available, a WebArgumentResolver might be more applicable.
