Question

我在运行Quartz Schdular程序时遇到异常。

以下是Trace

的例外情况

Mar 26, 2010 2:54:24 PM org.quartz.core.QuartzScheduler start
INFO: Scheduler DefaultQuartzScheduler_$_NON_CLUSTERED started.
Exception in thread "main" java.lang.IllegalArgumentException: Job class must implement the Job interface.
    at org.quartz.JobDetail.setJobClass(JobDetail.java:291)
    at org.quartz.JobDetail.<init>(JobDetail.java:138)
    at com.Quarrtz.RanchSchedule.main(RanchSchedule.java:18)

我已加入Quartz-1.7.2.jar和我的课程路径Quartz-all-1.7.2.jar以及commom-logging 1.1.jar和jdk 6

这是我从[JavaRanch] [1]

复制并粘贴的一个例子

上页的第一个例子

public interface Job {

    void execute (JobExecutionContext ctx);
}

public class RanchJob implements Job {

    public void execute (JobExecutionContext ctx) throws JobExecutionException {
        System.out.println("[JOB] Welcome at JavaRanch");
    }
}

public class RanchSchedule {

    public static void main (String[] args) {       
        try {
            SchedulerFactory factory = new org.quartz.impl.StdSchedulerFactory();

            Scheduler scheduler = factory.getScheduler();
            scheduler.start();

            JobDetail jobDetail = new JobDetail("ranchJob", null, RanchJob.class);
            // Fires every 10 seconds
            Trigger ranchTrigger = TriggerUtils.makeSecondlyTrigger(10); 
            ranchTrigger.setName("ranchTrigger");

            scheduler.scheduleJob(jobDetail, ranchTrigger);
        } catch (SchedulerException ex) {
            ex.printStackTrace();
        }
    }
}

您是否在源代码中编写了Job接口？

public interface Job {
    void execute (JobExecutionContext ctx);
}

如果是这样，您不必这样做。 Quartz有自己的Job接口（在quartz.jar中）。只保留你的RanchJob和RanchSchedule类，它应该可以工作。
