1.簡單的controller進行呼叫測試。

@RestController
@RequestMapping("/quartz")
public class QuartzApiController {
    @Autowired
    private QuartzScheduler quartzScheduler;

    @RequestMapping("/start")
    public void startQuartzJob() {
        try {
            quartzScheduler.startJob();
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @RequestMapping("/info")
    public String getQuartzJob(String name, String group) {
        String info = null;
        try {
            info = quartzScheduler.getJobInfo(name, group);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
        return info;
    }

    @RequestMapping("/modify")
    public boolean modifyQuartzJob(String name, String group, String time) {
        boolean flag = true;
        try {
            flag = quartzScheduler.modifyJob(name, group, time);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
        return flag;
    }

    @RequestMapping(value = "/pause")
    public void pauseQuartzJob(String name, String group) {
        try {
            quartzScheduler.pauseJob(name, group);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @RequestMapping(value = "/pauseAll")
    public void pauseAllQuartzJob() {
        try {
            quartzScheduler.pauseAllJob();
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    @RequestMapping(value = "/delete")
    public void deleteJob(String name, String group) {
        try {
            quartzScheduler.deleteJob(name, group);
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

}
 

2.處理任務的service。

@Configuration // 配置
public class QuartzScheduler {
    
    // 任務排程
    @Autowired
    private Scheduler scheduler;


    /**
     * 開始執行所有任務
     * 
     * @throws SchedulerException
     */
    public void startJob() throws SchedulerException {
        startJob1(scheduler);
        scheduler.start();
    }

    
    /**
     * 開始某個任務
     * @throws SchedulerException
     */
    private void startJob1(Scheduler scheduler) throws SchedulerException {
        // 通過JobBuilder構建JobDetail例項，JobDetail規定只能是實現Job介面的例項
        // JobDetail 是具體Job例項
        JobDetail jobDetail = JobBuilder.newJob(SchedulerQuartzJob1.class).withIdentity("job1", "group1").build();
        // 基於表示式構建觸發器
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");
        // CronTrigger表示式觸發器 繼承於Trigger
        // TriggerBuilder 用於構建觸發器例項
        CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("job1", "group1")
                .withSchedule(cronScheduleBuilder).build();
        scheduler.scheduleJob(jobDetail, cronTrigger);
    }


    /**
     * 獲取Job資訊
     * @param name
     * @param group
     * @return
     * @throws SchedulerException
     */
    public String getJobInfo(String name, String group) throws SchedulerException {
        TriggerKey triggerKey = new TriggerKey(name, group);
        CronTrigger cronTrigger = (CronTrigger) scheduler.getTrigger(triggerKey);
        return String.format("time:%s,state:%s", cronTrigger.getCronExpression(),
                scheduler.getTriggerState(triggerKey).name());
    }
    

    /**
     * 修改某個任務的執行時間
     * @param name
     * @param group
     * @param time
     * @return
     * @throws SchedulerException
     */
    public boolean modifyJob(String name, String group, String time) throws SchedulerException {
        Date date = null;
        TriggerKey triggerKey = new TriggerKey(name, group);
        CronTrigger cronTrigger = (CronTrigger) scheduler.getTrigger(triggerKey);
        String oldTime = cronTrigger.getCronExpression();
        if (!oldTime.equalsIgnoreCase(time)) {
            CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(time);
            CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(name, group)
                    .withSchedule(cronScheduleBuilder).build();
            date = scheduler.rescheduleJob(triggerKey, trigger);
        }
        return date != null;
    }


    /**
     * 暫停所有任務
     *
     * @throws SchedulerException
     */
    public void pauseAllJob() throws SchedulerException {
        scheduler.pauseAll();
    }


    /**
     * 暫停某個任務
     *
     * @param name
     * @param group
     * @throws SchedulerException
     */
    public void pauseJob(String name, String group) throws SchedulerException {
        JobKey jobKey = new JobKey(name, group);
        JobDetail jobDetail = scheduler.getJobDetail(jobKey);
        if (jobDetail == null)
            return;
        scheduler.pauseJob(jobKey);
    }


    /**
     * 恢復所有任務
     *
     * @throws SchedulerException
     */
    public void resumeAllJob() throws SchedulerException {
        scheduler.resumeAll();
    }


    /**
     * 恢復某個任務
     *
     * @param name
     * @param group
     * @throws SchedulerException
     */
    public void resumeJob(String name, String group) throws SchedulerException {
        JobKey jobKey = new JobKey(name, group);
        JobDetail jobDetail = scheduler.getJobDetail(jobKey);
        if (jobDetail == null)
            return;
        scheduler.resumeJob(jobKey);
    }
    

    /**
     * 刪除某個任務
     *
     * @param name
     * @param group
     * @throws SchedulerException
     */
    public void deleteJob(String name, String group) throws SchedulerException {
        JobKey jobKey = new JobKey(name, group);
        JobDetail jobDetail = scheduler.getJobDetail(jobKey);
        if (jobDetail == null)
            return;
        scheduler.deleteJob(jobKey);
    }


}
 

3.定義任務。

public class SchedulerQuartzJob1 implements Job{
    private void before(){
        System.out.println("任務開始執行");
    }

    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        before();
        System.out.println("開始："+System.currentTimeMillis());
        // TODO 業務
        System.out.println("結束："+System.currentTimeMillis());
        after();
    }

    private void after(){
        System.out.println("任務一次執行結束");
    }

}
 

4.監聽器載入注入定時器。

@Configuration
public class ApplicationStartQuartzJobListener implements ApplicationListener<ContextRefreshedEvent>{
    @Autowired
    private QuartzScheduler quartzScheduler;

    /**
     * 初始啟動quartz
     */
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        try {
            quartzScheduler.startJob();
            System.out.println("任務已經啟動...");
        } catch (SchedulerException e) {
            e.printStackTrace();
        }
    }

    /**
     * 初始注入scheduler
     * @return
     * @throws SchedulerException
     */
    @Bean
    public Scheduler scheduler() throws SchedulerException{
        SchedulerFactory schedulerFactoryBean = new StdSchedulerFactory();
        return schedulerFactoryBean.getScheduler();
    }


}

5.pom.xml中需要加入的依賴。

<dependency>
	<groupId>org.quartz-scheduler</groupId>
	<artifactId>quartz</artifactId>
	<version>2.2.1</version>
</dependency>
