我正在编写一些单元测试,并希望将 TimeTree 与 Spring 存储库一起使用,以将事件节点自动附加到时间树。类似这个问题,但我使用的是 boot 2.0 和 SDN5。我认为我的主要问题是我不知道如何设置配置,因此我的存储库和我的 TimeTree 使用相同的 GraphDatabaseService。我的@Confuration 是这样的:
@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;
}
}
我的测试看起来像这样:
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();
有很多错误,但我认为它们都源于这个:
Bean instantiation via factory method failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to
