Answer 1

I guess that 404 is not related to your HttpMessageConverter. I had same 404-issue and the reason was that I forgot that only requests matching <url-pattern> are sent to DispatcherServlet (I changed request mapping from *.do to *.json). Maybe this is your case also.

In addition to the answers here..

if you are using jquery on the client side, this worked for me:

Java:

@RequestMapping(value = "/ajax/search/sync") 
public ModelAndView sync(@RequestBody Foo json) {

Jquery (you need to include Douglas Crockford's json2.js to have the JSON.stringify function):

$.ajax({
    type: "post",
    url: "sync", //your valid url
    contentType: "application/json", //this is required for spring 3 - ajax to work (at least for me)
    data: JSON.stringify(jsonobject), //json object or array of json objects
    success: function(result) {
        //do nothing
    },
    error: function(){
        alert('failure');
    }
});
