在Spring MVC 3.2中实现JSONP

这样简单的方法

@RequestMapping(value = "/jsonp", method = RequestMethod.GET)@ResponseBodypublic String jsonp(@RequestParam("c")String callBack) throws Exception{    ObjectMapper objectMapper = new ObjectMapper();    Map<String, Object> map = new HashMap<String, Object>();    map.put("data", "<p>jsonp data<p>");    return objectMapper.writevalueAsString(new JSonPObject(callBack,map));}
