JAVA项目（maven）使用钉钉SDK（获取token、用户等）

 将SDK放一个文件里，记住文件地址。D:\eclipse-workspace\项目名\模块名\lib

win+r cmd 敲下面的命令：

【进入相应盘】   D: 

【进入文件地址】   cd D:\eclipse-workspace\项目名\模块名

【运行命令】  mvn install:install-file -DgroupId=com.dingtalk.api -DartifactId=top-api-sdk-dev -Dversion=ding-open-mc-SNAPSHOT -Dfile=lib/taobao-sdk-java-auto_1479188381469-20200319.jar -Dpackaging=jar -DgeneratePom=true

然后在pom文件中增加以下内容：

<!--钉钉工具包-->
     <dependency>
         <groupId>com.dingtalk.api</groupId>
         <artifactId>top-api-sdk-dev</artifactId>
         <version>ding-open-mc-SNAPSHOT</version>
     </dependency>

 

理解：普通的maven项目都会在pom里配置好jar，项目自动从maven中配置的镜像地址（就是网上）自己把jar包下载到你设置的位置

但是有些jar包下载不下来，可以先本地保存，然后像上面那样用命令把jar包挂到maven设置的jar库里去

JAVA后台代码：
import com.dingtalk.api.DefaultDingTalkClient;
import com.dingtalk.api.DingTalkClient;
import com.dingtalk.api.request.OapiDepartmentListRequest;
import com.dingtalk.api.request.OapiGettokenRequest;
import com.dingtalk.api.request.OapiMessageCorpconversationAsyncsendV2Request;
import com.dingtalk.api.request.OapiUserSimplelistRequest;
import com.dingtalk.api.response.OapiDepartmentListResponse;
import com.dingtalk.api.response.OapiGettokenResponse;
import com.dingtalk.api.response.OapiMessageCorpconversationAsyncsendV2Response;

import com.taobao.api.ApiException;

import com.dingtalk.api.response.OapiDepartmentListResponse.Department;

import com.dingtalk.api.request.*;
import com.dingtalk.api.response.*;
