公开Restful webservices，获得没有json密钥的响应

Question

我在数据库（Mysql）的帮助下在netbeans中创建了restful webservices， 从数据库创建实体，然后从实体创建restful webservice，使用存储过程，我从webservice获得响应。

退回outpout：

{"attendee":[[13885,4,"Mar 28, 2018 5:36:45 PM",null,null,"Active but not Vefied","5f4db43b5ad965aa1dfd27a2c8feb1e7","9828409828","Sanjay",null,"Sanjay Sharma",null,"Mr"null,"Attendee","sanjay",null,"Mar 28, 2018","Sharma",null,"RegularUser",13882,"password",null]],"success":true}

必填项：

{"attendee":[["**key**":"13885","**above key is missing**":"4","Mar 28, 2018 5:36:45 PM",null,null,"Active but not Vefied","5f4db43b5ad965aa1dfd27a2c8feb1e7","9828409828","Sanjay",null,"Sanjay Sharma",null,"Mr"null,"Attendee","sanjay",null,"Mar 28, 2018","Sharma",null,"RegularUser",13882,"password",null]],"success":true}

json的响应键中的

为空 。

GsonBuilder gsonBuilder = new GsonBuilder();
    Gson gson = gsonBuilder.create();
    JsonObject jo = new JsonObject();
    List<Attendee> resultList = new ArrayList<>();
    em = this.getEntityManager();
    resultList = em.createNamedStoredProcedureQuery("LOGIN_VALID").setParameter("USER", userName).setParameter("PASS", password).getResultList();
    JsonElement je = gson.toJsonTree(resultList, new TypeToken<List<Attendee>>() {
    }.getType());
    com.google.gson.JsonArray jsonArray = gson.toJsonTree(resultList).getAsJsonArray();
    System.out.println(" " + jsonArray);
    JsonArray jsonA = je.getAsJsonArray();
    //  System.out.println(" jsonAt=rray "+jsonA);
    if (resultList != null) {
        jo.add("attendee", je);
        jo.addProperty("success", Boolean.TRUE);
    } else {
        jo.addProperty("success", Boolean.FALSE);
    }

    return Response.ok(jo.toString()).build();
