1、完成钉钉认证才能使用此功能
2、需要登录控制台进行创建应用操作 https://open-dev.dingtalk.com/fe/app
3、需要设置 权限范围及通讯录权限设置 参考 https://www.ngui.cc/el/778161.html?action=onClick

实体分为授权跟参数

授权实体

@Data
public class DingDingAuthorization {private String appKey;private String appSecret;private String agentId;
}

参数实体

@Data
public class DingDingMsgData {private String mobile;private String title;private String content;private String url;
}

发送调用方法类

@Slf4j
@Component
public class DingDingSendMsgHandle {public boolean sendDingDingOneMessage(DingDingAuthorization dingAuthorization, DingDingMsgData dingDingMsgData) {return DingDingUtil.sendDingDingMessage(dingAuthorization,dingDingMsgData);}public  void sendDingDingBatchMessage(DingDingAuthorization dingAuthorization, List<DingDingMsgData> dingDingMsgData){dingDingMsgData.stream().forEach(s->{DingDingUtil.sendDingDingMessage(dingAuthorization,s);});}
}

调用 

@Autowired
private DingDingSendMsgHandle dingDingSendMsgHandle;

//授权参数自行组装

DingDingAuthorization dingDingAuthorization = new DingDingAuthorization();
//发送参数自行组装
DingDingMsgData dingDingMsgData = new DingDingMsgData();boolean i=  dingDingSendMsgHandle.sendDingDingOneMessage(dingDingAuthorization,dingDingMsgData);
