title: How to add a MediaType to the MappingJackson2HttpMessageConverter instead of the RestTemplate
body: <p>My question is very similar to <a href="https://stackoverflow.com/questions/9854855/how-to-change-mediatype-for-mappingjacksonhttpmessageconverter-in-oauth2resttemp">How to change MediaType for MappingJacksonHttpMessageConverter in OAuth2RestTemplate</a> but different in many ways.</p>
  
  <p>I am using Spring 4 with SprintBoot. I want to use <code>RestTemplate</code> to query a Zimbra web services. The web service returns "JSON SOAP". It's really just JSON response in a format of a SOAP message.</p>
  
  <p>Unfortunately, the response comes back as <code>text/javascript; charset=utf-8</code> so the Message Converter fails as it does not find any converter for that media type.</p>
  
  <p>How do I tell <code>MappingJackson2HttpMessageConverter</code> to consider this content type the same as regular JSON?</p>
