按照设置尤里卡服务器的教程进行操作。我遵循所有步骤，但在它应该工作时运行它，但它因以下错误而崩溃：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.cloud.netflix.eureka.server.EurekaServerInitializerConfiguration': Unsatisfied dependency expressed through field 'eurekaServerBootstrap'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eurekaServerBootstrap' defined in class path resource [org/springframework/cloud/netflix/eureka/server/EurekaServerAutoConfiguration.class]: Unsatisfied dependency expressed through method 'eurekaServerBootstrap' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eurekaServerContext': Invocation of init method failed; nested exception is java.lang.IllegalStateException: java.lang.RuntimeException: Cannot Create new Replica Node :JerseyReplicationClient: http://localhost:8010/eureka/apps/:

在Java中，我需要获取两个参数，Runnable和Delay，单位是毫秒，并且需要在延迟时间内运行Runnable。这需要在单线程中运行，如果使用不同的参数值调用该方法并且前一个任务尚未完成，则应将其保留在队列中。

public void runScheduledTask(Runnable task, long delay) {
   // ...
}

...

runScheduledTask(task1, 10); // at 00:00:00.000
runScheduledTask(task2, 10); // at 00:00:00.005

当用task2调用该方法时，task1尚未开始/完成，因为有延迟10，因此task2应该存储在队列中。在这种情况下，有没有办法检查任务 1 是否已完成？由于这应该在当前线程中运行，所以我不知道可以使用哪些类或工具。
