有沒有辦法用MongoDB/Java將BasicDBObject渲染成Map<String,String>？有沒有辦法使用MongoDB/Java將BasicDBObject渲染爲Map <String，String>？
public Map<String,String> getObjectByKeyValue(String dbname, String collname, String key, String value) {
Map<String,String> result = new HashMap<String, String>();
DB db = mongo.getDB(dbname);
DBCollection coll = db.getCollection(collname);
BasicDBObject query = new BasicDBObject();
query.put(key, value);
DBCursor cur = coll.find(query);
while (cur.hasNext()){
DBObject obj = (DBObject) cur.next(); // Correct, or use BasicDBObject?
// How to get each pair stored in the object be pushed into a Map<String,String> ?
}
return result;
}
