## What it is
The official Aliyun (Alibaba Cloud) OSS SDK for Java, enabling Java developers to interact with Aliyun Object Storage Service. It is the V1 SDK, now superseded by the rewritten alibabacloud-oss-java-sdk-v2.

## Use cases
- upload files to aliyun oss from java
- download objects from alibaba cloud object storage
- manage oss buckets from a java application
- generate signed urls for oss objects
- integrate aliyun oss into a spring boot app
- list and delete objects in an oss bucket

## When to choose
- you are maintaining an existing Java project already using the V1 SDK
- you need Java 1.6 compatibility
- your team is familiar with the V1 API and does not need V2 features

## When to avoid
- you are starting a new Java project - use alibabacloud-oss-java-sdk-v2 instead
- you need advanced features like paginators, transmission managers, or file-like operations
- you work outside the JVM ecosystem
