title: Spring Boot - Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported
body: <p>Im using the latest Spring Boot version, currently 2.2.2-RELEASE.  </p>
  
  <p>I have this endpoint:  </p>
  
  <pre><code>@RequestMapping(method = RequestMethod.POST, value = "/test", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
  public ResponseEntity&lt;?&gt; post(@RequestParam(required = false) MultiValueMap&lt;?, ?&gt; paramMap) throws Exception {
      // CODE
      return new ResponseEntity&lt;&gt;(HttpStatus.OK);
  }
  </code></pre>
  
  <p>If I call it (from postman) setting the body as a x-www-form.urlencoded all is fine and I receive my 200 OK status code.   </p>
  
  <p>But if I modify the above endpoint (adding another parameter) as follows:  </p>
  
  <pre><code>@RequestMapping(method = RequestMethod.POST, value = "/test", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
  public ResponseEntity&lt;?&gt; post(@RequestParam(required = false) MultiValueMap&lt;?, ?&gt; paramMap, RequestEntity&lt;?&gt; req) throws Exception {
      // CODE
      return new ResponseEntity&lt;&gt;(HttpStatus.OK);
  }
  </code></pre>
  
  <p>I receive this error:   </p>
  
  <pre><code>{
      "timestamp": 1576961587242,
      "status": 415,
      "error": "Unsupported Media Type",
      "message": "Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported",
      "path": "/test"
  }
  </code></pre>
  
  <p>Something is missing?  </p>
  
  <p>Thank you in advance.</p>
