FormEncoder bug

Line 95 in 98e51d1

if (MAP_STRING_WILDCARD.equals(bodyType)) {

if bodyType‘s typeName is "java.util.map<java.lang.String, java.lang.Object>" cannot correct match

eg:
@RequestLine("POST /user")
@headers("Content-Type: application/x-www-form-urlencoded")
void addUser (Map<String,Object> stringObjectMap);

It also cannot recognize the org.springframework.util.MultiValueMap.

So for example this method will never send a body:

  @PostMapping(consumes = MediaType.APPLICATION_FORM_URLENCODED)
  ResponseEntity<ObjectNode> requestForSomething(@RequestBody MultiValueMap<String, String> params);

The workaround for this is

  @PostMapping(consumes = MediaType.APPLICATION_FORM_URLENCODED)
  ResponseEntity<ObjectNode> requestForSomething(@RequestBody Map<String, ? extends Object> params);
