Quartz的任务的临时启动和暂停和恢复

在项目中需要手动启停某些服务，那么需要有一个控制这些任务的类。由于任务是有Quartz控制的，我们只需要通过Quartz的相关的API实现相关的功能即可。

package com.gbsoft.rpt.qtz;import java.util.Date;import java.util.List;import java.util.Map;import org.quartz.JobDataMap;import org.quartz.JobDetail;import org.quartz.JobKey;import org.quartz.Scheduler;import org.quartz.SchedulerException;import org.quartz.SchedulerFactory;import org.quartz.Trigger;import org.quartz.TriggerKey;import org.quartz.impl.StdSchedulerFactory;import org.quartz.impl.matchers.GroupMatcher;/** * 一个简单的quartz任务管理器 * @author 123 * */public class QuartzSchedule {private static  Scheduler scheduler=getScheduler();/** * 创建一个调度对象 * @return * @throws SchedulerException */private static Scheduler getScheduler() {    SchedulerFactory sf = new StdSchedulerFactory();

创建一个Job任务：

package com.gbsoft.rpt.qrz;import java.util.Date;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException;/** * 一个简单的quartz调用job * @author 123 * */public class HelloJob implements Job {    private static Logger _log = LoggerFactory.getLogger(HelloJob.class);    public HelloJob() {    }    public void execute(JobExecutionContext context)        throws JobExecutionException {        _log.info("Hello World! - " + new Date());    }}

创建触发器和调用相关的Job

package com.gbsoft.rpt.qrz;import static org.quartz.DateBuilder.evenMinuteDate;import static org.quartz.JobBuilder.newJob;import static org.quartz.TriggerBuilder.newTrigger;import java.util.Date;

import org.quartz.JobDetail;import org.quartz.Scheduler;import org.quartz.Trigger;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * 一个简单的测试quartz任务管理器测试类 * @author 123 * */public class QuartzScheduleMain {    /** *  * @throws Exception */    public void run() throws Exception {        Logger log = LoggerFactory.getLogger(QuartzScheduleMain.class);        log.info("------- Initializing ----------------------");        // First we must get a reference to a scheduler        //从调度管理器中获取调度对象        Scheduler sched = QuartzScheduleMgr.getInstanceScheduler();        log.info("------- Initialization Complete -----------");        // computer a time that is on the next round minute        Date runTime = evenMinuteDate(new Date());        log.info("------- Scheduling Job  -------------------");        // define the job and tie it to our HelloJob class        //创建相关的job信息        JobDetail job = newJob(HelloJob.class)            .withIdentity("job1", "group1")            .build();                // Trigger the job to run on the next round minute        //创建一个触发器的名称        Trigger trigger = newTrigger()            .withIdentity("trigger1", "group1")            .startAt(runTime)            .build();                // Tell quartz to schedule the job using our trigger        //设置调度相关的Job        sched.scheduleJob(job, trigger);        log.info(job.getKey() + " will run at: " + runTime);          // Start up the scheduler (nothing can actually run until the         // scheduler has been started)        //启动调度任务        sched.start();        log.info("------- Started Scheduler -----------------");        try {            Thread.sleep(25L * 1000L);             // executing...        } catch (Exception e) {        }        //暂时停止Job任务开始执行        log.info("-------pauseJob.. -------------");        sched.pauseJob(job.getKey());                try {            Thread.sleep(10L * 1000L);         } catch (Exception e) {        }        log.info("------- resumeJob... -------------");        //恢复Job任务开始执行        sched.resumeJob(job.getKey());        try {            Thread.sleep(10L * 1000L);             // executing...        } catch (Exception e) {        }                        // wait long enough so that the scheduler as an opportunity to         // run the job!        log.info("------- Waiting 65 seconds... -------------");        try {            // wait 65 seconds to show job            Thread.sleep(65L * 1000L);             // executing...        } catch (Exception e) {        }        // shut down the scheduler        log.info("------- Shutting Down ---------------------");        sched.shutdown(true);        log.info("------- Shutdown Complete -----------------");    }    public static void main(String[] args) throws Exception {        QuartzScheduleMain example = new QuartzScheduleMain();        example.run();    }}
