title: How to change swagger response for exception
body: <p>I am using spring boot with swagger for REST API services. The swagger returns the response in the following format when exception occurs</p>
  
  <pre><code>    {
    "timestamp": 1449742584285,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "com.foo.exception.NotFoundException",
    "message": "User with id 1 not found",
    "path": "/user/1"
  }
  </code></pre>
  
  <p>Instead of returning the detailed response I want to show only the message. Also all the time the server tkhrows an <code>RuntimeException</code>.</p>
  
  <p>How to achieve swagger to retun only the message.</p>
