钉钉扫码登录 java

 java获取扫码登录后的钉钉id 从而可以查出员工具体信息 部门具体信息

1.注册钉钉企业账号

注册地址

https://oa.dingtalk.com/register.html

开发文档地址

https://open-doc.dingtalk.com/microapp/isv

注册完支行查看corpId corpSecret

创建扫码登录使用的app ID、appSecret

2.下载钉钉sdk （http://img.alicdn.com/top/i1/LB1l7mXv0knBKNjSZKPXXX6OFXa）把jar包传到私有maven仓库

<dependency>
<groupId>com.taobao</groupId>
<artifactId>taobao-sdk-java-auto</artifactId>
<version>20180815</version>
</dependency>

（仅供参考）

 3.java代码使用示例（redis工具类没贴出来）
