How to use FindIterable to get the specific field from mongodb using java

Question

Here,I'm trying to retrieve the status field if the name matches.How to use FindIterable instead of DBCursor.Can anyone please help me out ...

My code:

  public String getStatus(String name) throws Exception{
             MongoClient mongo = new MongoClient("localhost",27017);
             MongoDatabase db = mongo.getDatabase("counter");
             MongoCollection<Document> col = db.getCollection("status");

            Document query = new Document();
            query.put("name", name);
            query.put("status", 1);

            Document fields = new Document();
            fields.put("status", 1);
            fields.put("_id", 0);

             DBCursor cursor = collection.find(query,fields);

             while(cursor.hasNext()){
                    System.out.println(cursor.next());
                }

        return "SUCCESS";
        }

Answer 1

You simply load the cursor into a FindIterable object like so:

FindIterable<Document> docs = col.find(query);
if (docs == null) {
    //no values found
}

for(Document doc : docs) {
    //access documents e.g. doc.get()
}

Answer 2

You simply load the cursor and fetch the document into the Document. for more info visit https://dzone.com/articles/basic-java-crud-operations

DBCursor cursor = items.find(query);
while (cursor.hasNext()) {
    Document document = cursor.next();
    System.out.println(document.getString("identifier"));
}
