MongoDB Java Driver Array

Question

I am trying to save a set of tags within a mongodb document e.g.

{ id:"104454", tags:["tag1", "tag2"] }

I am struggling to figure out how to do this with the Java Driver though. I thought I would use BasicDBList but this doesnt seem to be right.

Could someone help please?

Thanks in advance.

I have already read through this but as far as I can see it doesn't show how to create JSON arrays?

You can use simple arrays and then you can do something like: doc.put("tags", array)

When saving arrays into MongoDB with Java, according to the online doc, you can use anything that extends List.

So, using your example, that would be something like the following:

ArrayList tags = new ArrayList();
tags.add("tag1");
tags.add("tag2");

BasicDBObject doc = new BasicDBObject(new ObjectId(), tags);
