Executing Mongo like Query (JSON)through Java

Question

I was wondering if there is a way to execute mongo like query directly through Java i.e. we give mongoDB like query as a String to a function in Java driver for mongoDB as a

Answer 1

Yes, there is way, by passing the filter as a string. Example:

BasicDBObject query = BasicDBObject.parse("{userId: {$gt: \"1\"}}");
FindIterable dumps = crapCollection.find(query);

You can Also use com.mongodb.util.JSON, but I don't recommend it. It's less descriptive.

DBObject dbObject = (DBObject)JSON.parse("{userId: {$gt: \"1\"}}");

Please notice that this might be vulnerable to SQL injections because you parse/build the filter yourself.

I recommend using Jongo's parameterized query.
