前提：
获取到阿里云账号的AccessKey ID 和AccessKey Secret：
操作步骤：
1.添加Pom依赖
<dependency><groupId>com.aliyun</groupId><artifactId>tea-openapi</artifactId><version>0.0.7</version></dependency><dependency><groupId>com.aliyun</groupId><artifactId>openplatform20191219</artifactId><version>3.0.1</version></dependency><dependency><groupId>com.aliyun</groupId><artifactId>oss-client</artifactId><version>3.0.2</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>3.7</version></dependency><dependency><groupId>com.aliyun</groupId><artifactId>aliyun-java-sdk-core</artifactId><version>4.5.13</version></dependency>

注意事项：
在添加代码块之后，在使用try内包含流会报：“try-with-resource are not supported at language level “5”错误。通过IDEA自带的alt+enter修复功能设置一个版本到7即可。
更多参考：
衣冠の禽兽CSDN文档：IDEA 报错：not supported at language level "5"
ChaseDreamBoy CSDN文档：idea maven 出现：Try-with-resources are not supported at language level '5'
