官方地址：对象存储 OSS_云存储服务
示例代码地址：GitHub aliyun-oss-spring-boot-sample
上传策略：服务端签名后直传
通过服务器处理签名，但不处理文件，保证加密的同时，减轻服务的压力
开通
登录阿里云账号
选择oss服务进行开通
进入OSS管理控制台，创建一个bucket
鼠标悬浮右上角头像，点击AccessKey管理
选择使用子用户AccessKey
创建一个用户，并分配oss的读写权限
得到AccessKey ID、AccessKey Secret
得到Endpoint（即外网访问地址）
搭建子项目

GulimallThirdPartyApplication.java
@SpringBootApplication @EnableDiscoveryClient public class GulimallThirdPartyApplication { public static void main(String[] args) { SpringApplication.run(GulimallThirdPartyApplication.class, args); } }
测试类：
@SpringBootTest(classes = GulimallThirdPartyApplication.class) class GulimallThirdPartyApplicationTest { @Autowired OSSClient ossClient; @Test public void testUpload() throws FileNotFoundException { //上传文件流。 InputStream inputStream = new FileInputStream("C:\\Users\\admin\\Pictures\\1.jpg"); ossClient.putObject("bucketName", "Naruto.jpg", inputStream); // 关闭OSSClient。 ossClient.shutdown(); System.out.println("上传成功."); } }
结果：
前端请求跨域配置：
注意
注意使用新的starter，aliyun-oss-spring-boot-starteraliyun-oss-spring-boot-starter的sdk-oss版本（3.1.0）过低，当前springboot 版本较高（2.6.11）所以添加了更高版本的sdk-ossDescription:An attempt was made to call a method that does not exist.

视频的oss.yml配置已经不再适用，请参考阿里的示例代码配置配置跨域后生效需要一点时间
