问题 I am trying to get the Graphaware Framework and UUID running on a GrapheneDB instance. I have followed the instructions to zip the JAR and neo4j.properties files and uploaded using the GrapheneDB Web Interface but UUID's are not added when I create a new node. neo4j.properties file dbms.unmanaged_extension_classes=com.graphaware.server=/graphaware com.graphaware.runtime.enabled=true #UIDM becomes the module ID: com.graphaware.module.UIDM.1=com.graphaware.module.uuid.UuidBootstrapper #optional

问题 class Client include Neo4j::ActiveNode end > client = Client.new => #<Client uuid: nil, bot_client_id: nil, created_at: nil, email: nil, first_name: nil, last_name: nil, sms: nil, telegram_id: nil, updated_at: nil> My expectation is that the uuid would be populated. 回答1: The uuid is only populated once the node object has been saved. So you could either do: client = Client.create Or: client = Client.new client.save 来源： https://stackoverflow.com/questions/43535208/neo4j-uuid-is-not-created

问题 I am using Node.js to connect to a hosted GrapheneDB Neo4j database and when attempting to add about 1,500 records I get the following error: LockClient[19] can't wait on resource RWLock[NODE(248), hash=1917331445] since => LockClient[19] <-[:HELD_BY]- RWLock[INDEX_ENTRY(153122458561043471), hash=1171319680] <-[:WAITING_FOR]- LockClient[15] <-[:HELD_BY]- RWLock[NODE(248), hash=1917331445] The code that generates this comes from a route that takes a list of JSON objects and then stores them in
