quartz监控日志(二)添加监听器

上一章介绍监控job有三种方案,其实还有一个简单方案是实现quartz的TriggerListener。

上次我也试了这个方案,但是由于操作错误,导致没有监控成功,所以才选择分析源码来实现代理进行监控。

后面我看了些资料,并重新试了下,这种方案是可行的,并且非常方便。

首先实现TriggerListener,如下:

代码语言:javascript复制
public class MonitorTriggerListener implements TriggerListener {
    
    private final static Logger logger=Logger.getLogger(MonitorJobRunShell.class);
    private ThreadLocal<QuartzLog> localLog=new ThreadLocal<QuartzLog>();
    /**  
     * @see org.quartz.TriggerListener#getName()    
     */
    @Override
    public String getName() {
        return "MonitorTriggerListener";
    }
    
    /**  
     * @see org.quartz.TriggerListener#triggerComplete(org.quartz.Trigger, org.quartz.JobExecutionContext, int)    
     */
    @Override
    public void triggerComplete(Trigger arg0, JobExecutionContext jec, int arg2) {
        try {
            QuartzLog quartzLog=localLog.get();
            if(quartzLog==null)return ;
            quartzLog.setExeTime(jec.getJobRunTime());
            getService().update(quartzLog);
        } catch (Exception e) {
            logger.error("记录job结束时间异常",e);
        }catch (Throwable e) {
            logger.error("记录job结束时间出错",e);
        }
    }
    
    /**  
     * @see org.quartz.TriggerListener#triggerFired(org.quartz.Trigger, org.quartz.JobExecutionContext)    
     */
    @Override
    public void triggerFired(Trigger arg0, JobExecutionContext jec) {
        try {
            JobDetail jobDetail = jec.getJobDetail();
            System.out.println(localLog.get());
            QuartzLog quartzLog=getService().insert(jobDetail.getName());
            localLog.set(quartzLog);
            System.out.println(quartzLog);
        } catch (Exception e) {
            logger.error("记录job开始时间异常",e);
        }catch (Throwable e) {
            logger.error("记录job开始时间出错",e);
        }
    }
    
    /**  
     * @see org.quartz.TriggerListener#triggerMisfired(org.quartz.Trigger)    
     */
    @Override
    public void triggerMisfired(Trigger arg0) {
    }
    
    /**  
     * @see org.quartz.TriggerListener#vetoJobExecution(org.quartz.Trigger, org.quartz.JobExecutionContext)    
     */
    @Override
    public boolean vetoJobExecution(Trigger arg0, JobExecutionContext arg1) {
        return false;
    }
    private QuartzLogService getService(){
        return (QuartzLogService)BeanLocator.getBeanInstance("quartzLogService");
    }
}

然后在初始化StdSchedulerFactory时添加全局监听器,

代码语言:javascript复制
factory = new StdSchedulerFactory(configProperties);
   //启动调度
  scheduler = factory.getScheduler();
   TriggerListener myListener=new MonitorTriggerListener();
  scheduler.addGlobalTriggerListener(myListener);
  scheduler.start();

这样同样可以达到监控效果。
