S3Template

[maciejwalkowiak]

Introduce a higher level abstraction over S3Client providing Spring idiomatic way to perform common operations.

public interface S3Operations {

	String createBucket(String bucketName);

	void deleteBucket(String bucketName);

	void deleteObject(String bucketName, String key);

	void deleteObject(String s3Url);

	void store(String bucketName, String key, Object object);

	<T> T read(String bucketName, String key, Class<T> object);

	void upload(String bucketName, String key, InputStream inputStream) throws IOException;
	
	Resource download(String bucketName, String key) throws IOException;
}

public interface S3ObjectConverter {
	<T> RequestBody write(T o);
	<T> T read(InputStream is, Class<T> clazz);
}

store and read method would use under the hood S3ObjectConverter to store regular Java objects in S3 using serialization option of choice. By default we would configure Jackson2JsonS3ObjectConverter.
