背景：在工作中的一些告警需要发送钉钉通知，有的是发给个人，有的要发到群里，这时项目就需要接入钉钉，实现发消息的功能

1. 添加钉钉依赖

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>dingtalk</artifactId>
  <version>2.0.14</version>
</dependency>

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>alibaba-dingtalk-service-sdk</artifactId>
  <version>2.0.0</version>
</dependency>

2. 发送工作通知

发送通知需要使用access_token，获取token需要根据AppKey、AppSecret，所以需要在钉钉后台建一个应用，获许AppKey和AppSecret

2.1. 后台建一个应用

获取token文档：

https://open.dingtalk.com/document/orgapp/obtain-the-access_token-of-an-internal-app

发消息文档：

https://open.dingtalk.com/document/orgapp/asynchronous-sending-of-enterprise-session-messages

2.2. 详细代码如下

替换相应的配置就可以直接发送了

import com.aliyun.dingtalkoauth2_1_0.models.GetAccessTokenResponse;
import com.aliyun.tea.TeaException;
import com.dingtalk.api.DefaultDingTalkClient;
import com.dingtalk.api.DingTalkClient;
import com.dingtalk.api.request.OapiMessageCorpconversationAsyncsendV2Request;
import com.dingtalk.api.response.OapiMessageCorpconversationAsyncsendV2Response;

    }


    /**
     * 测试发送个人消息
     */
    public static void main(String[] args) throws Exception {
   
        sendMessage();
    }

}

3. 发送群消息

3.1. 群内建立机器人

获取secret和Webhook就可以发送了

文档：

https://open.dingtalk.com/document/orgapp/custom-bot-to-send-group-chat-messages

建立机器人步骤如下：

给机器人取个名字

安全设置必选选一个，这里选择加签，后面要用到，具体原因可以看文档

完成后又个Webhook，这个是发送消息用的url

3.2. 详细代码如下

替换相应的配置就可以直接发送了

import com.dingtalk.api.DefaultDingTalkClient;
import com.dingtalk.api.DingTalkClient;
import com.dingtalk.api.request.OapiRobotSendRequest;
import com.dingtalk.api.response.OapiRobotSendResponse;
