Did you annotate Band with @Entity("bands")
? I'm not sure what you're asking... Are you asking how to convert that json string in to a Band object? If so, look in to jackson
Converting JSON to entities and storing in mongoDB using morphia
Domanda
I have a JSON string being sent from a client (browser ).I want to save it to my mongoDB database which already has some collections defined by the user.I was able to successfully save objects using Morphia.But How can I do the same if I already have the JSON string being returned from client I want to put in the "bands" collection.
Mongo mongo = new Mongo("localhost");
Datastore datastore = new Morphia().createDatastore(mongo,
"bandmanager");
Band band = new Band();
band.setName("Punjabi band");
band.getMembers().add("Lucky1");
band.getMembers().add("Lucky2");
band.getMembers().add("Lucky3");
band.getMembers().add("Lucky4");
band.getMembers().add("Lucky5");
band.getMembers().add("Lucky6");
band.setGenre("Punjabi");
datastore.save(band);

If you already have a JSON object, you don't really need Morphia. You can simply do the following with the Java driver:
DBObject dbObject = (DBObject) JSON.parse(yourJsonString);

PS: Do not forget to sanitize the JSON you get from the client!
