Java – Convert JSON to MongoDB Object

Convert JSON to MongoDB Object in Java

JSON Data to Convert:

{
‘name’ : ‘javac’,
‘age’ : 6
}

Conversion Code:

import java.net.UnknownHostException;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.DBObject;
import com.mongodb.Mongo;
import com.mongodb.MongoException;
import com.mongodb.util.JSON;

public class App {

    public static void main(String[] args) {
        try {

            Mongo mongo = new Mongo("localhost", 27017);
            DB db = mongo.getDB("yourdb");
            DBCollection collection = db.getCollection("dummyColl");

            // convert JSON to DBObject directly
            DBObject dbObject = (DBObject) JSON.parse("{'name':'javac', 'age':6}");

            collection.insert(dbObject);

            DBCursor cursorDoc = collection.find();
            while (cursorDoc.hasNext()) {
                System.out.println(cursorDoc.next());
            }

            System.out.println("Done");

        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (MongoException e) {
            e.printStackTrace();
        }
    }

}

import java.net.UnknownHostException;

import com.mongodb.DB;

import com.mongodb.DBCollection;

import com.mongodb.DBCursor;

import com.mongodb.DBObject;

import com.mongodb.Mongo;

import com.mongodb.MongoException;

public class App {

public static void main(String[] args) {

try {

Mongo mongo = new Mongo("localhost", 27017);

DB db = mongo.getDB("yourdb");

DBCollection collection = db.getCollection("dummyColl");

// convert JSON to DBObject directly

DBObject dbObject = (DBObject) JSON.parse("{'name':'javac', 'age':6}");

collection.insert(dbObject);

DBCursor cursorDoc = collection.find();

while (cursorDoc.hasNext()) {

System.out.println(cursorDoc.next());

}

System.out.println("Done");

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (MongoException e) {

e.printStackTrace();

}

Output:

{ “_id” : { “$oid” : “4dc9ebb5237f275c2fe4959f”} , “name” : “javac” , “age” : 6}
