XXL-JOB实现钉钉报警

XXL-JOB实现钉钉报警

原生的xxl-job并没有钉钉报警功能，但是官方文档有写：可以很方便的集成钉钉报警功能，即新增一个实现 "com.xxl.job.admin.core.alarm.JobAlarm" 接口的告警实现即可

 

1.代码结构

 

2.修改 JobFailMonitorHelper

如果不配置邮箱的话，是不会触发报警的。所以要修改下com.xxl.job.admin/core/thread下的JobFailMonitorHelper

 

3.DingJobAlarm钉钉报警实现

如果在定时任务配置页面。负责人一项配置的是手机号，那么报警消息推送的时候就会有@艾特功能。
