Java 使用嵌入式数据库的单元测试中的Graphaware时间树过程

更新：我在neo4j时间树源代码中发现了一些类似的测试，但使用了GraphaReintegrationTest，它扩展了ServerIntegrationTest。所以我尝试用下面的代码为我的测试创建一个GraphDatabaseService Bean，但仍然没有成功。我发现没有为该数据库实例注册名为ga.timetree.events.attach的过程。这不可能吗

@Bean
  public GraphDatabaseService graphDatabaseService() {
    GraphDatabaseService gds = new TestGraphDatabaseFactory().newImpermanentDatabaseBuilder().newGraphDatabase();
    Procedures procedures = (Procedures)((GraphDatabaseFacade) gds).getDependencyResolver().resolveDependency(Procedures.class);
    try {
        ClassPathProcedureUtils.registerAllProceduresAndFunctions(procedures);
    }catch (Exception ex) {
        log.error("error", ex);
    }
    return gds;
}

=====================

与之类似，但我使用的是Spring Boot 2、SDN5和neo4j 3.2.5、graphaware和时间树。我有自动事件附件设置，我看到事件被保存到时间树中，但我不能使用cypher使用过程调用进行查询。我得到一个错误：

Caused by: org.neo4j.ogm.exception.CypherException: Error executing Cypher; Code: Neo.ClientError.Procedure.ProcedureNotFound; Description: There is no procedure with the name `ga.timetree.range` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
at org.neo4j.ogm.drivers.embedded.request.EmbeddedRequest.executeRequest(EmbeddedRequest.java:176)

我没有看到链接问题中回答的TimeTreeProcedures类。在嵌入式/单元测试中仍然支持这一点吗

另外，如果支持，我想使用CustomRootTimeTree。我可以在过程调用中定义自定义根树id的任何帮助或指向cypher的指针也将非常感谢。谢谢你的帮助

测试：

目前回购硬编码开始/结束：

    public interface WorkoutRepository extends Neo4jRepository<Workout, Long> {

        @Query("CALL ga.timetree.range({start: 1506826887000, end: 1512097287, create: false})")
        Iterable<Workout> findWorkouts();

    }

我最终能够通过在neo4j源代码中调试使其工作。测试和使用过程的测试在中，它使用ClassPathProcedureUtils类从target/classes目录加载类。它寻找@Procedure注释，并将处理这些类，从而使这些过程变得可用。如果不修改它以从JAR加载类以及目标/类，我唯一能让它工作的方法就是将neo4j timetree项目的目标/类输出复制到我的项目目标/类输出目录中，尽管这是一个黑客攻击

更新： 我还可以通过直接使用以下工具注册所需的程序来实现：

@Bean
public GraphDatabaseService graphDatabaseService() {
    GraphDatabaseService gds = new TestGraphDatabaseFactory().newImpermanentDatabaseBuilder().newGraphDatabase();
    try {
        ClassPathProcedureUtils.registerAllProceduresAndFunctions(procedures);
        Procedures procedures = ((GraphDatabaseFacade)gds).getDependencyResolver().resolveDependency(Procedures.class);
        procedures.registerProcedure(TimedEventsProcedure.class);
        procedures.registerProcedure(TimeTreeProcedure.class);
        procedures.registerFunction(TimedEventsProcedure.class);
        procedures.registerFunction(TimeTreeProcedure.class);
      }catch (Exception ex) {
        log.error("error", ex);
      }
      return gds;
}

@Bean
public GraphDatabaseService graphDatabaseService() {
    GraphDatabaseService gds = new TestGraphDatabaseFactory().newImpermanentDatabaseBuilder().newGraphDatabase();
    try {
        ClassPathProcedureUtils.registerAllProceduresAndFunctions(procedures);
        Procedures procedures = ((GraphDatabaseFacade)gds).getDependencyResolver().resolveDependency(Procedures.class);
        procedures.registerProcedure(TimedEventsProcedure.class);
        procedures.registerProcedure(TimeTreeProcedure.class);
        procedures.registerFunction(TimedEventsProcedure.class);
        procedures.registerFunction(TimeTreeProcedure.class);
      }catch (Exception ex) {
        log.error("error", ex);
      }
      return gds;
}
