A slightly more realistic example, makes use of Spring's willingness to magically do stuff for you. Also not having to construct a MappingJackson2HttpMessageConverter (and the underlying ObjectMapper) for every request may have very real performance implications.

Let spring handle serializing and writing the response body.
Json controller now replies with a Message object
instead of a Map. Creating tons of maps is memory
intensive, plus this tests Jackson's ability to
serialize a bean instead of a Map.

Thanks @ryantenney! This was a great Spring addition. Preliminary numbers show a healthy improvement across the board.
