MongoDB & Java DBRef 使用

Question

So let's say I have a patient document in MongoDB. It has things such as first name, last name, etc… I am trying to add to the current document a list of providers (which is another collection, by DBRef, as I am using POJO. How would I append multiple providers in Java to the document?

Answer 1

One way to do this is by just appending to a document like this:

Document doc = new Document("user", userObject).append("providers", providersObject);

providersObject would be your list of providers.
