Finally found the solution, I get the same result than with the original request.
Mongo Driver 3 :
Aggregate doc
MongoCollection<Document> collection = database.getCollection("myCollection");
AggregateIterable<Document> output = collection.aggregate(Arrays.asList(
new Document("$unwind", "$views"),
new Document("$match", new Document("views.isActive", true)),
new Document("$sort", new Document("views.date", 1)),
new Document("$limit", 200),
new Document("$project", new Document("_id", 0)
.append("url", "$views.url")
.append("date", "$views.date"))
));
// Print for demo
for (Document dbObject : output)
{
System.out.println(dbObject);
}
You can make it more readable with static import :
import static com.mongodb.client.model.Aggregates.*;
.
See koulini answer for complet example.
Mongo Driver 2 :
Aggregate doc
Iterable<DBObject> output = collection.aggregate(Arrays.asList(
(DBObject) new BasicDBObject("$unwind", "$views"),
(DBObject) new BasicDBObject("$match", new BasicDBObject("views.isActive", true)),
(DBObject) new BasicDBObject("$sort", new BasicDBObject("views.date", 1)),
(DBObject) new BasicDBObject("$limit", 200),
(DBObject) new BasicDBObject("$project", new BasicDBObject("_id", 0)
.append("url", "$views.url")
.append("date", "$views.date"))
)).results();
// Print for demo
for (DBObject dbObject : output)
{
System.out.println(dbObject);
}
