我有密码

@RequestMapping(value = "/graph", method = RequestMethod.POST)
@ResponseBody
public HttpServletResponse graphImport() {

    JSONParser parser = new JSONParser();
    GraphJson savedGraph = new GraphJson();

    try {

        Object obj = parser.parse(new FileReader("graph.json"));

        JSONObject jsonObject = (JSONObject) obj;

        GraphJson graph = new GraphJson();
        graph.setSource(jsonObject.toString());
        session.save(graph);

        savedGraph = session.get(GraphJson.class, 1);

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParseException e) {
        e.printStackTrace();
    }

    System.out.println("CREATED");
    return resp;
    //return "id :" + savedGraph.getId() + ", " + savedGraph.getSource();
}

当我使用

curl http://localhost:8080/graph

当我向该URL发送一个POST请求时，我需要返回状态201，用于创建和方法POST。在这方面需要一些帮助。谢谢.
