16.SpringBoot2整合Quartz2-自定义Trigger监听器

Quartz 不仅可以监听Job, 还可以监听Trigger. 可以在Trigger触发前后或misfires时做一些操作. TriggerListener 和 JobListener 的创建和注册方式都比较像. 笔者就不做过多的介绍了

## 1. 自定义TriggerListener ##

/** * @Description: 监听HelloTrigger * @author: zongf * @date: 2019-04-12 16:30 */
    public class HelloTriggerListener extends TriggerListenerSupport { 
    
        Logger logger = LoggerFactory.getLogger(getClass());
    
        @Override
        public String getName() { 
            return getClass().getName();
        }
    
        @Override
        public void triggerFired(Trigger trigger, JobExecutionContext context) { 
            TriggerKey triggerKey = trigger.getKey();
            JobKey jobKey = context.getJobDetail().getKey();
            logger.info("触发器{}-触发定时任务:{}-开始",jobKey);
        }
    
        @Override
        public void triggerComplete(Trigger trigger, JobExecutionContext context, Trigger.CompletedExecutionInstruction triggerInstructionCode) { 
            TriggerKey triggerKey = trigger.getKey();
            JobKey jobKey = context.getJobDetail().getKey();
            logger.info("触发器{}-触发定时任务:{}-结束",jobKey);
        }
    }

## 2. 注册TriggerListener ##

*  笔者采用分组匹配模式, 匹配trigger分组group1下所有的Trigger
 *  当添加监听器时不指定Matcher时, 默认会监听所有的触发器

// 会向spring容器中新增一个beanName为scheduler的Scheduler, 此时容器中变有了两个Scheduler
    @Bean
    public Scheduler scheduler(Scheduler scheduler) throws Exception { 
        // 添加Scheduler 监听器
        scheduler.getListenerManager().addSchedulerListener(new MySchedulerListener());
    
        // 添加JobListener, 精确匹配JobKey
        KeyMatcher<JobKey> keyMatcher = KeyMatcher.keyEquals(JobKey.jobKey("helloJob", "group1"));
        scheduler.getListenerManager().addJobListener(new HelloJobListener(), keyMatcher);
    
        // 添加TriggerListener, 按组匹配
        GroupMatcher<TriggerKey> groupMatcher = GroupMatcher.groupEquals("group1");
        scheduler.getListenerManager().addTriggerListener(new HelloTriggerListener(), groupMatcher);
    
        return scheduler;
    }

## 3. 控制台输出 ##
