How to get UUID's from Spring data neo4j?

[chris_ds]

I need to get a UUID wich is valid across multiple vm's so my only conclusion was to retrieve a UUID from the neo4j db (or store and handle it there).

Is there an implementation I can rely on or do I have to implement this myself?

I did a research on this and only found low level neo4j hints, which stated I need a lock on a node, then get the id, increment it and write it back. But I am having trouble implementing this.

Any code snippets on how to do this would be greatly appreciated.

EDIT: I wrote a small hack and created a node that only has a unique id and a method that write locks this node and then increases that id. But a native, thread safe method would be way cooler.
