You can try inserting data in mongo using below sample code :-

您可以尝试使用以下示例代码在mongo中插入数据: -

String json = "{ 'name' : 'lokesh' , " +
                "'website' : 'howtodoinjava.com' , " +
                "'address' : { 'addressLine1' : 'Some address' , " +
                              "'addressLine2' : 'Karol Bagh' , " +
                              "'addressLine3' : 'New Delhi, India'}" +
                            "}";

DBObject dbObject = (DBObject)JSON.parse(json);

collection.insert(dbObject);

For your case you can Stringify your JSON object and then try inserting it into mongodb..

对于您的情况,您可以Stringify您的JSON对象,然后尝试将其插入mongodb ..
