java - S3 Presigned Url Callback -

is there way know if has uploaded generated public presigned url of s3? callback trigger servlet.

for example:

i created presigned url docs

amazons3 s3client = new amazons3client(new profilecredentialsprovider());   java.util.date expiration = new java.util.date(); long msec = expiration.gettime(); msec += 1000 * 60 * 60; // add 1 hour. expiration.settime(msec);  generatepresignedurlrequest generatepresignedurlrequest = new generatepresignedurlrequest(bucketname, objectkey); generatepresignedurlrequest.setmethod(httpmethod.put);  generatepresignedurlrequest.setexpiration(expiration);  url url = s3client.generatepresignedurl(generatepresignedurlrequest);   // use pre-signed url upload object. 

then, give url , if upload url, http://example.com/upload invoked data uploaded file.

you can use s3 event notifications generate notification. @ objectcreated event. notifications can filtered s3 prefix. (there samples in aws documentation on linked page.)
