关于java:XXLJOB实现钉钉报警

XXL-JOB 实现钉钉报警

原生的 xxl-job 并没有钉钉报警性能，然而官网文档有写：能够很不便的集成钉钉报警性能，即新增一个实现 “com.xxl.job.admin.core.alarm.JobAlarm” 接口的告警实现即可

1. 代码构造

2. 批改 JobFailMonitorHelper

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

3.DingJobAlarm 钉钉报警实现

如果在定时工作配置页面。负责人一项配置的是手机号，那么报警音讯推送的时候就会有 @艾特性能。
