issues in org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodArgumentResolver.EmptyBodyCheckingHttpInputMessage.EmptyBodyCheckingHttpInputMessage(HttpInputMessage inputMessage)

PushbackInputStream pushbackInputStream = new PushbackInputStream(inputStream);
int b = pushbackInputStream.read();
b=-1   body=null

The cause of the problem

Refer to the servlet specification:

3.1.1 When Parameters Are Available
The following are the conditions that must be met before post form data will be
populated to the parameter set:
1. The request is an HTTP or HTTPS request.
2. The HTTP method is POST.
3. The content type is application/x-www-form-urlencoded.
4. The servlet has made an initial call of any of the getParameter family of methods
on the request object.
If the conditions are not met and the post form data is not included in the parameter
set, the post data must still be available to the servlet via the request object’s input
stream. If the conditions are met, post form data will no longer be available for
reading directly from the request object’s input stream.

The @RequestBody annotation by default requires the body; you should switch to using @RequestBody(required=false) if you'd like to get a null input parameter in such cases instead of an exception.

I request input parameter is not null, but @RequestBody annotation MultiValueMap Exception
please see issues sample

Then I guess you're referring to the documented limitation of that approach:

As HttpPutFormContentFilter consumes the body of the request, it should not be configured for PUT or PATCH URLs that rely on other converters for application/x-www-form-urlencoded. This includes @RequestBody MultiValueMap<String, String> and HttpEntity<MultiValueMap<String, String>>.
