Quartz-Listener

监听器方便在Trigger执行完毕，Trigger执行错误等地方进行监听处理。

下面代码举个SchedulerListener的例子： 在Trigger最后一次执行的时候监听

 

import javax.annotation.Resource;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerListener;
import org.quartz.Trigger;
import org.quartz.TriggerKey;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;



/**
 *
 * @ClassName: SchedulerTriggerListener
 * @Description: Trigger监听器
 * @author zhuyb

 */
@Service("schedulerTriggerListenerService")
public class SchedulerTriggerListenerServiceImpl implements SchedulerListener {

    private static Logger logger = LoggerFactory.getLogger(SchedulerTriggerListenerServiceImpl.class);


    @Resource
    private SchedulerTriggersService schedulerTriggersService;

    @Resource
    private Scheduler scheduler;

    @Override
    public void jobScheduled(Trigger trigger) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobUnscheduled(TriggerKey triggerKey) {
        // TODO Auto-generated method stub

    }

    /**
     *
     * @Title: triggerFinalized
     * @Description: 轮询删除已被Quartz删除的内容
     * @param @param trigger
     * @author zhuyb
     * @throws
     */
    @Override
    public void triggerFinalized(Trigger trigger) {
        try {
            if (trigger.getNextFireTime() == null) {
                logger.info("Name="+trigger.getKey().getName()+ ", Group=" + trigger.getKey().getGroup());
                int i = schedulerTriggersService.deleteByNotExistInTriggers();
                logger.info("删除行数：" + i);
            }
        } catch (Exception e) {
            logger.error("监听器错误：",e);
        }
    }

    @Override
    public void triggerPaused(TriggerKey triggerKey) {

    }


    @Override
    public void triggersPaused(String triggerGroup) {
        // TODO Auto-generated method stub

    }


    @Override
    public void triggerResumed(TriggerKey triggerKey) {
        // TODO Auto-generated method stub

    }


    @Override
    public void triggersResumed(String triggerGroup) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobAdded(JobDetail jobDetail) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobDeleted(JobKey jobKey) {
    }


    @Override
    public void jobPaused(JobKey jobKey) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobsPaused(String jobGroup) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobResumed(JobKey jobKey) {
        // TODO Auto-generated method stub

    }


    @Override
    public void jobsResumed(String jobGroup) {
        // TODO Auto-generated method stub

    }


    @Override
    public void schedulerError(String msg, SchedulerException cause) {
        // TODO Auto-generated method stub

    }


    @Override
    public void schedulerInStandbyMode() {
        // TODO Auto-generated method stub

    }


    @Override
    public void schedulerStarted() {
    }


    @Override
    public void schedulerStarting() {

    }


    @Override
    public void schedulerShutdown() {
        // TODO Auto-generated method stub

    }


    @Override
    public void schedulerShuttingdown() {

    }


    @Override
    public void schedulingDataCleared() {
        // TODO Auto-generated method stub

    }

其实可以不必实现上述接口(有一堆你不需要的方法要重写)， 可以用SchedulerListenerSupport替代，只需要实现需要的方法。

 

 

监听注册：

 

 

       @Resource
private Scheduler scheduler;
@Resource
private SchedulerTriggerListenerServiceImpl schedulerTriggerListener;
       scheduler.getListenerManager().addSchedulerListener(schedulerTriggerListener);

 

以上就是一个监听器在Spring的完整集成。

 

 

具体很多其他的监听功能看业务需求吧

官方API差不多够用了：

 

结合我的另一篇文字：http://blog.csdn.net/wenniuwuren/article/details/42004539

就能解决Listener因为服务器关闭或重启Listener失效问题(其实就是重新注册监听器)。
