java - 每周在特定时间运行一次方法

Question

我到处找遍了。我查看了 Timers 和 Quartz，但仍然很困惑。

我有一个巨大的类执行不同的方法。这些方法之一是同步方法:

  public void onSynch()
  {
    String environment = validateEnvironment(env2);
    if (environment == null) return;
    try
    {
        RAT.synchronize(environment);
        onSelectEnv();
    }
    catch (Exception e)
    {
// TODO: tell user, log
    }   
  }

我需要能够创建一个计时器，每周在特定时间(例如每周五和下午 3:00)单独触发此方法一次。我无法创建单独的类。

我需要能够将调度程序放入此方法中，或者在其旁边创建另一个方法来创建调度程序并运行该同步方法。

Answer 1

我建议使用 QUARTZ 或 Spring Batch 进行调度程序作业。

尝试下面的Quartz 示例。引用:CronTrigger Tutorial , Example

你的Job.java

public class YourJob implements Job {
    public void execute(JobExecutionContext context) throws JobExecutionException {
        //here your operation
    }   
}

MySchedule.java

public class MySchedule {
    public void startUp() throws Exception {
        SchedulerFactory sf = new StdSchedulerFactory();
        Scheduler scheduler = sf.getScheduler();

        JobDetail yourJob = JobBuilder.newJob(YourJob.class).withIdentity("job1", "group1").build();

        /*Run every 30 seconds on Weekdays (Monday through Friday)*/
        Trigger trigger_1 = TriggerBuilder.newTrigger()
                .withIdentity("trigger1", "group1")
                .withSchedule(CronScheduleBuilder.cronSchedule("0,30 * * ? * MON-FRI"))
                .build();

        /*Run at 10am on the 1st and 15th days of the month*/
        Trigger trigger_2 = TriggerBuilder.newTrigger()
                .withIdentity("trigger2", "group1")
                .withSchedule(CronScheduleBuilder.cronSchedule("0 0 10am 1,15 * ?"))
                .build();

        /*Run at 3:30PM of every friday f month*/
        Trigger trigger_3 = TriggerBuilder.newTrigger()
                .withIdentity("trigger3", "group1")
                .withSchedule(CronScheduleBuilder.cronSchedule("0 18 30 ? * 6"))
                .build();

        scheduler.start();

        scheduler.scheduleJob(yourJob, trigger_1);
        scheduler.scheduleJob(yourJob, trigger_2);
        scheduler.scheduleJob(yourJob, trigger_3);

    }
}
