It worked for me using:

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"id":100}' http://localhost/api/postJsonReader.do

@RequestMapping(value = "/postJsonReader", method = RequestMethod.POST)
public @ResponseBody String processPostJsonData(@RequestBody IdOnly idOnly) throws Exception {
        logger.debug("JsonReaderController hit! Reading JSON data!"+idOnly.getId());
        return "JSON Received";
}

IdOnly is a simple POJO with an id property.
