Date parameter changes

In version 1, many operations accepted java.util.Date objects for time-based parameters. In version 2, these operations use java.time.Instant objects instead.

You can convert Date parameters automatically using the migration tool, or you can convert them manually by calling the toInstant() method on your Date object.

Example - Generate a presigned URL with an expiration date in version 1

// Generate a presigned URL that expires at a specific date
Date expiration = new Date(System.currentTimeMillis() + 3600000); // 1 hour from now
URL presignedUrl = s3Client.generatePresignedUrl(bucketName, keyName, expiration);

Example - Generate a presigned URL with an expiration instant in version 2

// Generate a presigned URL that expires at a specific instant
Date expiration = new Date(System.currentTimeMillis() + 3600000); // 1 hour from now
PresignedGetObjectRequest presignedRequest = presigner.presignGetObject(
    GetObjectPresignRequest.builder()
        .getObjectRequest(GetObjectRequest.builder()
            .bucket(bucketName)
            .key(keyName)
            .build())
        .signatureDuration(Duration.between(Instant.now(), expiration.toInstant()))
        .build());
