學習開源任務調度框架Quartz

1.首先第一步，固然是引入依賴啦，maven倉庫中最新的版本是2.3.0

<!-- https://mvnrepository.com/artifact/org.quartz-scheduler/quartz -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.3.0</version>
        </dependency>

2.進行一個簡單的例子，來學習此框架

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.newJob;
import static org.quartz.SimpleScheduleBuilder.simpleSchedule;
import static org.quartz.TriggerBuilder.newTrigger;

/**
 * QuartzTest class

 **/
public class QuartzTest {
    public static void main(String[] args) {
        try {

            //建立一個定時任務調度器
            Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
            //定時任務啓動
            scheduler.start();

            //新建一個觸發器，開始時間是如今，每間隔40s重複
            Trigger trigger = newTrigger().withIdentity("trigger1", "group1")
                    .startNow()
                    .withSchedule(simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
            //定義name/group


            //建立一個job任務數據，
            JobDetail job = newJob(HelloJob.class)
                    .withIdentity("job1", "group1")
                    .build();


            scheduler.scheduleJob(job, trigger);

            try {
                Thread.sleep(100*1000);  //爲毫秒級別，先執行100s再說
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            scheduler.shutdown();
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }
}

3.運行結果以下：
