com.mongodb.MongoException$CursorNotFound: cursor not found on server異常處理

java鏈接MongoDB處理大量數據時常常碰到cursor not found 的異常,事實上是超時所致

Exception in thread "main" com.mongodb.MongoException$CursorNotFound: cursor not found on server
        at com.mongodb.DBApiLayer$Result.init(DBApiLayer.java:379)
        at com.mongodb.DBApiLayer$Result._advance(DBApiLayer.java:426)
        at com.mongodb.DBApiLayer$Result.hasNext(DBApiLayer.java:408)
        at com.mongodb.DBCursor._hasNext(DBCursor.java:495)
        at com.mongodb.DBCursor.hasNext(DBCursor.java:515)

解決方法非常easy：
           DBCursor cursor = collection.find(condtion);
                cursor.addOption(com.mongodb.Bytes.QUERYOPTION_NOTIMEOUT);

僅僅要在查詢的DBCursor加入com.mongodb.Bytes.QUERYOPTION_NOTIMEOUT就解決！
