钉钉发送消息详细教程-- java

希望能对你有所帮助

首先是进行前期准备工作

流程

1. 随便申请一个企业钉钉（这个不用详细说了吧） 不用企业认证 只是成为管理员 （公司的话就跟管理员要管理员权限才能登进去）
2. 申请成功之后登陆开发者后台钉钉开发者后台
   
   3.进入首页点击应用开发-企业内部开发
   

4.进入到应用开发 进行应用创建




5.进行接口查看接口文档
我们以工作通知为例子

看一下文档 我们之后可以线上调试


获取token

用户ID获取 登陆钉钉后台通讯录查看钉钉



下面是硬货 直接复制到项目改一下就行了

/**
 * 项目中的常量定义类
 */
public class Constant {
    /**
     * 应用的AppKey，登录开发者后台，点击应用管理，进入应用详情可见
     */
    public static final String APPKEY = "XXX";
    /**
     * 应用的AppSecret，登录开发者后台，点击应用管理，进入应用详情可见
     */
    public static final String APPSECRET = "XXX";

    /**
     * 应用的agentdId，登录开发者后台可查看
     */
    public static final Long AGENTID = XXXL;

}

下面的无需改动只需要传值就行了

public class URLConstant {
    /**
     * 钉钉网关gettoken地址
     */
    public static final String URL_GET_TOKKEN = "https://oapi.dingtalk.com/gettoken";
    

    /**
     * 发送企业通知消息的接口url
     */
    public static final String MESSAGE_ASYNCSEND = "https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2";

}

import lombok.Data;

@Data
public class SendDingTalkBo {
    public final static SendDingTalkBo SEND_DING_TALK_BO = new SendDingTalkBo();
    private SendDingTalkBo (){

    }
    // 快递类型
    private String expressDeliveryType;
    // 快递单号
    private String expressDeliveryNumber;
    //快递节点时间
    private String expressDeliveryTime;
    //客服名字
    private String customerServiceName;
    // 品牌名称
    private String supplierName;
    // 通知人Userid
    private String UserId;
    // 快递状态
    private String expressDeliveryState;
    // 货物地址
    private String acceptAddress;
}

所需jar 外部引用需要下载注意 免费的jar

        <dependency>
            <groupId>com.taobao.top</groupId>
