MongoDB Java驱动程序3.1转换为数组查找

Question

In the older mongo drivers we could convert a DBCursor to array. How can I accomplish it using mongo Java driver 3.1?

I have looked into mongo java driver api and found only this way:

MongoHandler.getCollection().find().sort(docSort).limit(ConstMongo.LIMIT_PLAYERS)
                .forEach(new Block<Document>() {
                    @Override
                    public void apply(final Document document) {
                        arrResult.add(document.toJson());
                    }
                });

Is there a better and more clean way to do so? And if not, why did they change the way we can access array of documents?

Answer 1

In the Mongo 3.2 Java driver there is an into method that you can use to iterate over your results and put them into a collection

Example

List arrResult...
collection.find().into(arrResults);
