原文：本文介绍了JAVA+maven项目使用钉钉SDK获取token、用户，分享给大师，具体如下：+将SDK放置在一个文件中，记录文件地址。D: eclipse-workspace 项目名 模块名 lib win+r cmd 下的命令：[进入相应目录]

改写后：本文分享JAVA+maven项目通过钉钉SDK获取token和用户的方法。具体步骤包括：将SDK存入文件，并记录文件路径。在D盘eclipse-workspace目录下，项目名模块名lib文件夹内，使用win+r打开cmd，输入命令进入相应目录。

本文介绍了JAVA maven项目使用钉钉SDK获取token、用户，分享给大家，具体如下：

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：

D:

cd D:\eclipse-workspace\项目名\模块名

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：
