上一章介紹監控job有三種方案,其實還有一個簡單方案是實現quartz的TriggerListener。java
上次我也試了這個方案,可是因爲操做錯誤,致使沒有監控成功,因此才選擇分析源碼來實現代理進行監控。ide
後面我看了些資料,並從新試了下,這種方案是可行的,而且很是方便。spa
首先實現TriggerListener,以下:代理
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("記錄job結束時間異常",e); }catch (Throwable e) { logger.error("記錄job結束時間出錯",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("記錄job開始時間異常",e); }catch (Throwable e) { logger.error("記錄job開始時間出錯",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"); } }
而後在初始化StdSchedulerFactory時添加全局監聽器,code
factory = new StdSchedulerFactory(configProperties); //啓動調度 scheduler = factory.getScheduler(); TriggerListener myListener=new MonitorTriggerListener(); scheduler.addGlobalTriggerListener(myListener); scheduler.start();
這樣一樣能夠達到監控效果。blog
