how to get Object URL and Server-side encryption while returning S3ObjectSummary

Question

I have created a java service to return the meta-data of the S3 objects but in my json response it's not returning the Server-side encryption and Object URL

Here is my code

 @GetMapping(value = "/ListS3BucketsObjects")
    public List<S3ObjectSummary> ListS3BucketsObjects(@RequestParam String bucketName) {
        try {
            BasicAWSCredentials creds = new BasicAWSCredentials("xxxx",
                    "xxxxxxx");
            final AmazonS3 s3client = AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(creds))
                    .withRegion(Regions.US_EAST_1).build();
            ObjectListing objectListing = s3client.listObjects(bucketName);
            return objectListing.getObjectSummaries();
        } catch (Exception Ex) {
            throw Ex;
        }
    }

I'm getting result like this

[
    {
        "bucketName": "xxxx",
        "key": "xx",
        "size": 489583,
        "lastModified": "2020-01-01T06:59:52.000+0000",
        "storageClass": "STANDARD",
        "owner": {
            "displayName": "xxxxx",
            "id": "xxx"
        },
        "etag": "xxxxx"
    }]

how to get the Object URL and Server-side encryption?

Check this answer . Based S3ObjectSummary you can retrieve metadata:

ObjectMetadata objectMetadata = s3client.getObjectMetadata(bucketName, objectSummary.getKey());
