java实现钉钉通知

首先是pom文件

<!--钉钉新版服务端SDK-->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>dingtalk</artifactId>
            <version>1.3.23</version>
        </dependency>
        <!--钉钉旧版服务端SDK-->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>alibaba-dingtalk-service-sdk</artifactId>
            <version>2.0.0</version>
       </dependency>

然后sendDingDing类

package org.cloud.sonic.agent.tools;
//package com.example.demo.utils;

import com.dingtalk.api.DefaultDingTalkClient;
import com.dingtalk.api.DingTalkClient;
import com.dingtalk.api.request.OapiRobotSendRequest;
import com.dingtalk.api.response.OapiRobotSendResponse;
import com.taobao.api.ApiException;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.codec.binary.Base64;
import org.springframework.stereotype.Component;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;

        dingDingUtils.sendDingDing(url);
    }
}

其他类调用

String url = url_dingding;
DingDingUtils dingDingUtils = new DingDingUtils();
dingDingUtils.needSendInfo = new SimpleDateFormat("yyyy-MM-dd").format(new Date())+"\niOS"+"运行时检测到错误信息：请查收\n"+actual;
dingDingUtils.sendDingDing(url);
