Kendo ui 将mongodb json绑定到剑道网格
我对剑道UI非常陌生,遇到了如下类似的挑战(除了我不介意网格有一个固定的数据结构): Json看起来像:Kendo ui 将mongodb json绑定到剑道网格,kendo-ui,kendo-grid,Kendo Ui,Kendo Grid,我对剑道UI非常陌生,遇到了如下类似的挑战(除了我不介意网格有一个固定的数据结构): Json看起来像: [{"score"[{"physics:99", "chemistry" :95}]},{"score"[{"physics:99", "chemistry" :95}]}] 在过去几天里,我一直在努力,并尝试了以下方法: 以下是上述URL中的相关代码: while(cursor.hasNext()) { BasicDBObject obj = (Basic
[{"score"[{"physics:99", "chemistry" :95}]},{"score"[{"physics:99", "chemistry" :95}]}]
在过去几天里,我一直在努力,并尝试了以下方法:
以下是上述URL中的相关代码:
while(cursor.hasNext()) {
BasicDBObject obj = (BasicDBObject) cursor.next();
jsonobj = new JSONObject();
BasicDBList name = (BasicDBList) obj.get("Name");
jsonobj.put("Incident Date", obj.getString("Incident Date"));
jsonarray.put(jsonobj);
}
return jsonarray;
JSON json =new JSON();
String serialize = json.serialize(cursor);
但是剑道格网似乎拒绝了它。请协助。我的问题通过将返回的json格式化为适当的格式得到解决,如下所示: 发件人: 致: 因此,基本上我提取了score对象,放入我自己的hashmap中,然后返回json对象。请参见下面的示例代码: *
DB=mongoClient.getDB(“测试”);
DBCollection coll=db.getCollection(“mycol”);
BasicDBObject字段=新的BasicDBObject(“分数”,true)。追加(“\u id”,false);
BasicDBObject查询=新建BasicDBObject();
DBCursor cursor=coll.find(查询,字段)
while(cursor.hasNext()){
DBObject obj=cursor.next();
BasicDBList scoreList=(BasicDBList)obj.get(“分数”);
对于(int i=0;i
*我能够解决这个问题。问题在于mongoDB发送的json格式。我会尽快回复详细的更新。
