OptaPlanner HelloWorld VehicleRoutingSolution问题缺少easyScoreCalculatorClass或incrementalScoreCalculatorClass

我正在尝试运行 org.acme.vehiclerouting.solver.SolverManagerTest 的类 optaplanner-分布-8.29.0.最终 我刚下载的捆绑包。修改了,就像我把它复制到我自己的项目中一样。但是,我无法创建 SolverFactory ,可能是因为我没有在Spring中运行它,所以我尝试手动创建我的SolverManager,而不是依赖 @Inject 。

    VehicleRoutingSolution problem = DemoDataBuilder.builder().setMinDemand(1).setMaxDemand(2)
            .setVehicleCapacity(25).setCustomerCount(75).setVehicleCount(6).setDepotCount(2)
            .setSouthWestCorner(new Location(0L, 43.751466, 11.177210))
            .setNorthEastCorner(new Location(0L, 43.809291, 11.290195)).build();

    SolverManager<VehicleRoutingSolution, Long> solverManager;
    SolverConfig solverConfig = new SolverConfig()
            .withSolutionClass(VehicleRoutingSolution.class)
            .withEntityClasses(Vehicle.class)
            .withTerminationSpentLimit(Duration.ofSeconds(3));


    SolverFactory<VehicleRoutingSolution> configFactory = SolverFactory.create(solverConfig);

以上失败

java.lang.IollegalArgumentException:scoreDirectorFactory缺少easyScoreCalculatorClass或incrementalScoreCalculatorClass的配置。

我的ScoreDirectorFactory应该使用什么?我应该试着让@Inject工作吗?我更希望能够手动完成此配置,运行示例时会有很多神奇之处。
