web 后臺返回json格式數據的方式（status 406）

1.在類上使用注解?

@RestController
public class HttpComentInterface {}

2.在方法是使用注解??@ResponseBody

 　　@RequestMapping(path = "/interface/queryRemote", method = RequestMethod.POST) //可以指定請求方式@ResponseBody public RemoteCommentResultData queryCommentPage(@RequestBody QueryCommentParamDTO queryCommentParamDTO, HttpServletRequest request) {
}

3.使用 out

　　@RequestMapping(value ="/GetSomeInfos" ,produces = "application/json;charset=UTF-8")public ModelAndView getNearestAirport(HttpServletRequest request, HttpServletResponse response)throws Exception {logger.info("NearestAirportController.getNearestAirport begin");RemoteAirportsData data = nearestAirportService.getNearestAirports();response.setContentType("text/html;charset=UTF-8");response.setCharacterEncoding("UTF-8");String result = JSONObject.fromObject(data).toString();response.getWriter().print(result);logger.info("NearestAirportController.getNearestAirport end");return null;}

4.如果出現了 status 406 則是項目中缺少? jackson-core-asl-1.9.12.jar，jackson-mapper-asl-1.9.12.jar 這兩個包

引起的原因：
由于設置了@ResponseBody,要把對象轉換成json格式，缺少轉換依賴的jar包，故此錯。

?

也可以用response返回結果，就不用手動去加這兩個jar包了
