我无法第二次启动Akka Quartz调度程序。
我收到一个错误消息，说：

“插入构造函数时出错，org.quartz。调度程序异常：名为“QuartzScheduler~-application”的计划程序已存在”

public class JobModule extends AbstractModule implements ServiceGuiceSupport {

            @Override
            protected void configure() {
                //Akka Quartz Scheduler
                bind(QuartzSchedulerExtension.class).toProvider(SchedulerJobInitializer.class);

            }

            private static class SchedulerJobInitializer implements Provider<QuartzSchedulerExtension> {
                private QuartzSchedulerExtension quartzSchedulerExtension;

                @Inject
                public SchedulerJobInitializer(ActorSystem actorSystem) {
                        this.quartzSchedulerExtension = new QuartzSchedulerExtension((ExtendedActorSystem) actorSystem);
                }
                @Override
                public QuartzSchedulerExtension get() {
                    return quartzSchedulerExtension;
                }
            }
        }

       //Injecting in below class and it is failing

        public class JobScheduler {
            private final ActorSystem system;
            private final QuartzSchedulerExtension quartzSchedulerExtension;

            @Inject
            public JobScheduler(QuartzSchedulerExtension quartzSchedulerExtension,
                                 ActorSystem system) {
                this.quartzSchedulerExtension = quartzSchedulerExtension;
                this.system=system;
            }
        }
