title: JSON Associative array mapped using Spring MVC support
body: <p>If I have a JSON array like so:</p>
  
  <pre><code>{
  "type": "anAction", 
  "fired": "2011-09-16 20:00:00", 
  "data[id]": "1234", 
  "data[list_id]": "7890",
  "data[email]": "abc@xxx.com",
  "data[email][foo]": "blah"    
  }
  </code></pre>
  
  <p>Does someone know how I can use Spring's jacksonMessageConverter and maybe a custom ObjectMapper to convert those associative JSON arrays into Java objects?</p>
  
  <p>I'm using @RequestBody annotation for receiving the JSON string.</p>
  
  <p>Thanks!</p>
