title: FeignClient is changing the format of LocalDate passed to it
body: <p>I'm have a <code>@FeignClient</code> in my app:</p>
  <pre><code>@FeignClient(name=&quot;${mongo.service.id}&quot;, url=&quot;${mongo.service.url}&quot;)
  public interface MongoCustomerClaimInterface {
      @GetMapping(path = &quot;/api/customerClaim/countClaims/{businessDate}&quot;)
      List&lt;TransactionClaimStatusData&gt; countClaimsByStatusToBusinessDate(
      @PathVariable @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) 
      LocalDate businessDate);
  }
  </code></pre>
  <p>I call the feign method and passing it a formatted <code>LocalDate</code> variable, and printing it to the log:</p>
  <pre><code>LocalDate businessDate = getBusinessDate();
  LocalDate formattedDate = LocalDate.parse(businessDate.toString(), 
                                            DateTimeFormatter.ISO_DATE);
  log.info(&quot;formattedDate: &quot; + formattedDate);
  claimStatusDataList = mongoCustomerClaimInterface.countClaims(formattedDate);
  </code></pre>
  <p>The call generates <code>404</code> error and log:</p>
  <pre><code>2020-24-02 18:10:25.433 INFO  DashboardServiceImpl - formattedDate: 2020-02-23
  2020-24-02 18:10:25.440 DEBUG
  RequestMappingHandlerMapping:
  Looking up handler method for path /api/customerClaim/countClaims/2/23/20
  RequestMappingHandlerMapping:
  Did not find handler method for [/api/customerClaim/countClaims/2/23/20]
  </code></pre>
  <p>Although I pass a date in the format <code>yyyy-mm-dd</code> so it will match:</p>
  <ul>
  <li><code>@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)</code></li>
  <li>Feign <strong>somehow changes the date</strong> and then no matching url is found</li>
  </ul>
  <p>How can I prevent Feign from doing this and configure a uniform formatter?</p>
