阿里 对象存储OSS 云存储服务

基哥的奋斗历程2024-04-10 5:06

1.简介

对象存储服务(Object Storage Service ,OSS) 是一种 海量、安全、低成本、高可靠的云存储服务，适合存放任意类型的文件。容量和处理能力弹性扩展，多种存储类型供选择，全面优化存储成本。

2.如何使用。参考文档

看文档，说的很明白，这里就不演示了

3. SpringCloudAlibaba-OSS

spring-cloud-alibaba/README-zh.md at 2022.x · alibaba/spring-cloud-alibaba · GitHub

好像新版本没有starter了

自己封装一下原生API吧
