J'écris des tests unitaires et je veux utiliser TimeTree avec des répertoires Spring, pour attacher automatiquement des nœuds d'événements à un arbre temporel. Quelque chose comme problème this, mais j'utilise boot 2.0 et SDN5. Je pense que mon principal problème est que je ne sais pas comment configurer la configuration de sorte que mes dépôts et mon TimeTree utilisent le même GraphDatabaseService. Mon @Confuration est comme ceci:Comment configurer mes propres GraphDatabaseService et GraphAwareRuntime dans un test unitaire avec boot 2.0 et Neo4j SDN5
@Configuration
public class SpringConfig {
@Bean
public SessionFactory sessionFactory() {
// with domain entity base package(s)
return new SessionFactory(configuration(), "org.neo4j.boot.test.domain");
}
@Bean
public org.neo4j.ogm.config.Configuration configuration() {
return new org.neo4j.ogm.config.Configuration.Builder()
.uri("bolt://localhost")
.build();
}
@Bean
public Session getSession() {
return sessionFactory().openSession();
}
@Bean
public GraphDatabaseService graphDatabaseService() {
return new GraphDatabaseFactory()
.newEmbeddedDatabase(new File("/tmp/graphDb"));
}
@Bean
public GraphAwareRuntime graphAwareRuntime() {
GraphDatabaseService graphDatabaseService = graphDatabaseService();
GraphAwareRuntime runtime = GraphAwareRuntimeFactory
.createRuntime(graphDatabaseService);
runtime.registerModule(new TimeTreeModule("timetree",
TimeTreeConfiguration
.defaultConfiguration()
.withAutoAttach(true)
.with(new NodeInclusionPolicy() {
@Override
public Iterable<Node> getAll(GraphDatabaseService graphDatabaseService) {
return null;
}
@Override
public boolean include(Node node) {
return node.hasLabel(Label.label("User"));
}
})
.withRelationshipType(RelationshipType.withName("CREATED_ON"))
.withTimeZone(DateTimeZone.forTimeZone(TimeZone.getTimeZone("GMT+1")))
.withTimestampProperty("createdOn")
.withResolution(Resolution.DAY)
// .withCustomTimeTreeRootProperty("timeTreeName")
.withResolution(Resolution.HOUR), graphDatabaseService));
runtime.start();
return runtime;
}
}
Et mon test ressemble à ceci:
User user = new User("Michal");
user.setCreatedOn(1431937636995l);
userRepository.save(user);
GraphUnit.assertSameGraph(graphDb, "CREATE (u:User {name:'Michal', createdOn:1431937636995})," +
"(root:TimeTreeRoot)," +
"(root)-[:FIRST]->(year:Year {value:2015})," +
"(root)-[:CHILD]->(year)," +
"(root)-[:LAST]->(year)," +
"(year)-[:FIRST]->(month:Month {value:5})," +
"(year)-[:CHILD]->(month)," +
"(year)-[:LAST]->(month)," +
"(month)-[:FIRST]->(day:Day {value:18})," +
"(month)-[:CHILD]->(day)," +
"(month)-[:LAST]->(day)," +
"(day)<-[:CREATED_ON]-(u)"
);
GraphUnit.printGraph(graphDb);
graphDb.shutdown();
Il y a une foule d'erreurs, mais je pense qu'ils proviennent tous de celui-ci:
Bean instantiation via factory method failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to
instantiate [org.springframework.data.repository.support.Repositories]:
Factory method 'repositories' threw exception; nested exception is
org.springframework.beans.factory.UnsatisfiedDependencyException: Error

Un grand merci, on dirait que je suis de retour dans les affaires. Des bières sur moi si jamais nous nous rencontrons! –
