xxl-job实现钉钉群机器人报警功能-优快云博客

本文链接：https://blog.youkuaiyun.com/it_world_/article/details/120785289

该博客详细介绍了如何在XXL-JOB中配置DingTalk机器人，以便当任务执行失败时能自动发送报警通知。首先在钉钉群创建自定义机器人并设置安全关键字，然后在XXL-JOB中编写DingTalk报警功能的实现类，通过RestTemplate发送POST请求到Webhook地址来发送钉钉消息。最后，在创建任务时将群机器人的access_token填入报警邮件中，确保报警功能正常工作。

1.首先在钉钉群创建自定义机器人
在这里插入图片描述
安全设置自定义关键字

2.xxl-job中编写钉钉报警功能的实现类在com.xxl.job.admin.core.alarm.impl下

package com.xxl.job.admin.core.alarm.impl;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;
