BSON ObjectID (Morphia) representation in Typescript/Angular2 Project

Question

I have a Java class representing a customer with some properties like name, adress etc. And I have the property:

@Id
@Property("_id")
private ObjectId id;

The customer will be fetched from a mongoDB. Everything is fine and all properties are filled. Then I try to transport data via REST to a angular2 client I have a Customer representation in typescript

export class Customer {
    public id: string <---

Mapping inside rest call in client

.map((response: Response) => <Customer> response.json()) 

what do I need to put here, that the property will be mapped and that I can use it within the angular client. I've tried to install bson-objectid via npm, but I have no idea how to get it to map the id property. All the others are working fine.

Solution found! Create a

public YourAdapterName extends XMLAdapter<String, ObjectID> {
   @Override
   public String marshal(ObjectId v) throws Exception {
       return v.toString();
   }

   @Override
   public ObjectId unmarshal(String v) throws Exception {
       return new ObjectId(v);
   }
}

This Adapter returns the string representation of the ObjectID and I can use

id: string 

in Typescript.
