使用 GraphAware Timetree 进行测试

Question

我已经开始为 neo4j 使用 GraphAware 时间树，到目前为止效果还不错。现在我正在尝试研究如何对使用 neo4j 时间树的代码进行单元/集成测试。

我已经整理了一些代码如下......但我仍然收到消息：

org.neo4j.ogm.exception.CypherException: Error executing Cypher "Neo.ClientError.Procedure.ProcedureNotFound"; Code: Neo.ClientError.Procedure.ProcedureNotFound; Description: There is no procedure with the name `ga.timetree.events.attach` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

我在正确的轨道上吗？

        TimeTreeConfiguration timeTreeConfiguration = TimeTreeConfiguration.defaultConfiguration();
        TimeTreeModule timeTreeModule = new TimeTreeModule("TT.1", timeTreeConfiguration, super.getGraphDatabaseService());

        GraphAwareRuntime runtime = GraphAwareRuntimeFactory.createRuntime(super.getGraphDatabaseService());
        runtime.registerModule(timeTreeModule);
        runtime.start();
    }

    @After
    public void clearDatabase() {
        neo4jOperations.query("match (n) detach delete n;", new HashMap<>());
        neo4jOperations.clear();

    }

}

请将您的 AbstractTest() 构造函数更改为如下所示：

public AbstractTest() {
    new SessionFactory("myproject.model.pojos").openSession();

    TimeTreeConfiguration timeTreeConfiguration = TimeTreeConfiguration.defaultConfiguration();
    TimeTreeModule timeTreeModule = new TimeTreeModule("TT.1", timeTreeConfiguration, super.getGraphDatabaseService());

    TimeTreeProcedures.register(super.getGraphDatabaseService());

    GraphAwareRuntime runtime = GraphAwareRuntimeFactory.createRuntime(super.getGraphDatabaseService());
    runtime.registerModule(timeTreeModule);
    runtime.start();
}

注意添加的行：TimeTreeProcedures.register(super.getGraphDatabaseService());
