Question

我正在学习石英调度程序框架，作为基础，我开始使用“Hello World”打印常规间隔。

这是我的SampleScheduler

public class SampleScheduler {
public static void main(String arfs[]) {
    try {
        Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
        scheduler.start();
        System.out.println("Scheduler Started...");

        JobDetail job = new JobDetail("job1","group1",SampleJobInter.class);
        Trigger trigger = new SimpleTrigger("trigger1",Scheduler.DEFAULT_GROUP,new Date(),null,SimpleTrigger.REPEAT_INDEFINITELY,60L*1000L);
        scheduler.scheduleJob(job, trigger);
        scheduler.shutdown();
        System.out.println("Scheduler Stopped..");  
    } catch(SchedulerException e) {

    }

}
}

这是我的SampleJobInter.class

public class SampleJobInter implements Job {

SampleJobInter(){}
@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
    // TODO Auto-generated method stub
    System.out.println("Hello World at "+new Date());
}

}

输出结果是

Scheduler Started...
Scheduler Stopped..

我没有得到所需的输出。我在控制台中运行它。我需要做任何配置或什么？请帮帮我

Answer 1

在安排作业运行后scheduler.start()放置scheduler.scheduleJob...

更新：我对org.life.java更正了。陈述的顺序不会产生太大影响。麻烦的来源是shutdown()调用。只要未在其上发出明确的 shutdown 命令，调度程序的合同[javadoc]就会继续运行。如果从代码中删除该行，则可以正常工作。

我是从零开始创建的，效果很好。!!
我建议你将你的代码与这个ans比较，并在catch中记录异常，这样你就会有好主意。
