Overview

First public release of storage-s3 – a lightweight S3 storage abstraction for Spring Boot based on AWS SDK v2.

Features

• StorageService interface with basic operations:
  • save(key, InputStream, length, contentType)
  • update(key, InputStream, length, contentType)
  • load(key)
  • delete(key)
• S3StorageServiceImpl – implementation using AWS SDK v2 (S3)
• S3StorageProperties – configuration via storage.s3.* properties:
  • enabled
  • bucket
  • endpoint
  • region
  • access-key
  • secret-key
  • prefix
• Spring Boot auto-configuration:
  • creates S3Client
  • exposes a StorageService bean
• Works with any S3-compatible provider (AWS S3, MinIO, etc.)
