一.文件上传

我们在OSS页面中找到SDK下载，点击SDK示例，找到帮助文档。

点击JAVA并安装

在安装SDK中找到在Maven项目中加入依赖项(推荐方式)

将其中的依赖复制到pom文件中去。

<dependency><groupId>com.aliyun.oss</groupId><artifactId>aliyun-sdk-oss</artifactId><version>3.17.4</version>
</dependency>

如果JDK版本是1.9以上，下面的也要复制到pom文件当中去。

<dependency><groupId>javax.xml.bind</groupId><artifactId>jaxb-api</artifactId><version>2.3.1</version>
</dependency>
<dependency><groupId>javax.activation</groupId><artifactId>activation</artifactId><version>1.1.1</version>
</dependency>
<!-- no more than 2.3.3-->
<dependency><groupId>org.glassfish.jaxb</groupId><artifactId>jaxb-runtime</artifactId><version>2.3.3</version>
</dependency>

引入后继续找到后续参考中的“对象/文件”

点击上传文件

选择简单上传
