Neo4j TimeTree en Spring Data Neo4j 4.0
Estoy tratando de utilizar la biblioteca timetree en mi proyecto spring data neo4j 4.0.0.
Como se detalla en esta página,https://github.com/graphaware/neo4j-timetree, He editado mi archivo neo4j.properties para habilitar la conexión automática de eventos, agregar dependencia de timetree a mi gradle y establecer una propiedad 'creationDate' en el nodo de eventos con tipo de datos Long. Aunque todo se ve como debería ser, todavía no crea ningún árbol de tiempo.
Aquí está mi archivo neo4j.property:
# Runtime must be enabled like this
com.graphaware.runtime.enabled=true
# A Runtime module that takes care of attaching the events like this (TT is the ID of the module)
com.graphaware.module.TT.1=com.graphaware.module.timetree.module.TimeTreeModuleBootstrapper
# Nodes which represent events and should be attached automatically have to be defined
com.graphaware.module.TT.event=hasLabel('StructureVersionChange'),hasLabel('RuleVersionChange'),hasLabel('FilterVersionChange')
# Optionally, a property on the event nodes that represents the the time (long) at which the event took place must be specified (defaults to "timestamp")
com.graphaware.module.TT.timestamp=creationDate
# Optionally, a resolution can be specified (defaults to DAY)
com.graphaware.module.TT.resolution=SECOND
# Optionally, a time zone can be specified (defaults to UTC)
com.graphaware.module.TT.timezone=CEST
# Optionally, a relationship type with which the events will be attached to the tree can be specified (defaults to AT_TIME)
com.graphaware.module.TT.relationship=CREATED_ON
# autoAttach must be set to true
com.graphaware.module.TT.autoAttach=true
En realidad, antes de esto intenté usar la versión API JAVA de Timetree para mi proyecto, pero luego estaba realmente confundido por el tipo de parámetro del constructor timetree, que es Node. Mientras que, en primavera, mis nodos tienen tipos de sus clases.
Gracias de antemano y su sugerencia sería muy apreciada!
