How can I manually describe an example input for a java @RequestBody Map<String, String>? : <p>I am designing an api where one of the POST methods that takes a <code>Map&lt;String, String&gt;</code> of any key value pairs.</p>

<pre><code>@RequestMapping(value = "/start", method = RequestMethod.POST)
public void startProcess(
    @ApiParam(examples = @Example(value = {
        @ExampleProperty(
            mediaType="application/json",
            value = "{\"userId\":\"1234\",\"userName\":\"JoshJ\"}"
        )
    }))
    @RequestBody(required = false) Map&lt;String, String&gt; fields) {
    // .. does stuff
}
</code></pre>

<p>I would like to provide an example input for <code>fields</code> but I can't seem to get it to render in the swagger output. Is this not the correct way to use <code>@Example</code>?</p>
