我的疑問？

1. 怎麼實現job和trigger的可配置呢？
   例如我想執行一個類，但是呢？如果這個類定義了，是不是就固定了？除非可以額外傳引數，google下真的可以傳引數。【How to pass instance variables into Quartz job?】

2. 怎麼實現任務的終止呢？
   不是排程器的終止，是任務的終止。
   Try make your job implements org.quartz.InterruptableJob, and then you may call org.quartz.Scheduler.interrupt(JobKey).

// quartz.properties
org.quartz.scheduler.instanceName = MyScheduler
org.quartz.threadPool.threadCount = 3
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

 

package com.qlkj;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class HelloJob implements Job {
    @Override
    public void execute(JobExecutionContext var1) throws JobExecutionException{
        System.out.println("hello world");
        System.out.println(System.currentTimeMillis());
    }


}
 

package com.qlkj;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.quartz.impl.StdSchedulerFactory;

import static org.quartz.JobBuilder.*;
import static org.quartz.TriggerBuilder.*;
import static org.quartz.SimpleScheduleBuilder.*;


public class QuartzTest {

    public static void main(String[] args) {

        try {
            // Grab the Scheduler instance from the Factory
            Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

            // and start it off
            scheduler.start();

// define the job and tie it to our HelloJob class
            JobDetail job = newJob(HelloJob.class)
                    .withIdentity("job1", "group1")
                    .build();

            // Trigger the job to run now, and then repeat every 40 seconds
            Trigger trigger = newTrigger()
                    .withIdentity("trigger1", "group1")
                    .startNow()
                    .withSchedule(simpleSchedule()
                            .withIntervalInSeconds(5)
                            .repeatForever())
                    .build();

            // Tell quartz to schedule the job using our trigger
            scheduler.scheduleJob(job, trigger);

//            scheduler.shutdown();

        } catch (SchedulerException se) {
            se.printStackTrace();
        }
    }
}

 

CronTrigger

CronTrigger使用cron-expressions進行任務觸發，cron表示式從左到右依次代表著
Seconds
Minutes
Hours
Day-of-Month
Month
Day-of-Week
Year (optional field)

trigger = newTrigger()
    .withIdentity("trigger3", "group1")
    .withSchedule(cronSchedule("0 0/2 8-17 * * ?"))
    .forJob("myJob", "group1")
    .build();
