title: Swagger+Spring: is it possible to preserve the fields order in the payload?
body: <p>Assuming my payload class is:</p>
  
  <pre><code>public class Payload {
    private final long id;
    private final String aField;
  }
  </code></pre>
  
  <p>springfox will sort the payload fields in the lexicographical order which will produce the following payload spec:</p>
  
  <pre><code>{
    "aField": "string",
    "id": 0
  } 
  </code></pre>
  
  <p>Is there any control parameter which tells the springfox to preserve the original fields order?</p>
