title: Spring JSON converter. How to bind different types
body: <p>I have an ajax call with data: "{"timeLeft": 12:33, "cheked": true}". On the clienside timeleft format: HH:MM, but on the serverside we need to convert it to milliseconds (Long). How to do that with MappingJackson2HttpMessageConverter?
  In Spring after submitting form we can use PropertyEditors. Is there something similar for json data in Jackson Converters? Thanks</p>
