1.When I am using AmazonS3Client to upload file on amazon s3 file store. 2.when I am trying to upload multiple files at a time it gives exceptions: but same file multiple th
This answer was wrote from the guy of AWS Hanson:
Is it possible that the input stream that is specified in the request has already been fully read?
If the input stream is a file stream, have you tried specifying the original file in the request instead of the input stream of the file?
I saw that error message when I was trying to do a S3.putObject(MyObject);
I had to update objectMetadata.setContentLength( [length of your content] );
For example:
String dataset= "Some value you want to add to S3 Bucket";
ObjectMetadata objectMetadata= new ObjectMetadata();
InputStream content= new ByteArrayInputStream(dataset.getBytes("UTF-8"));
objectMetadata.setContentLength(content.available());
objectMetadata.setSSEAlgorithm(ObjectMetadata.AES_256_SERVER_SIDE_ENCRYTION);
...
byte[] f = IOUtils.toByteArray(inputStream); // This reads all bytes of the input stream
ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentLength(f.length);
metadata.setContentType(contentType); //Content type of the uploaded file
metadata.setHeader("filename", fileName);
s3.putObject(bucketName, key, new ByteArrayInputStream(f), metadata); // Here we create a new ByteArrayInputStream so S3 client get happy.
Improving @iucasddaniel answer with sample code.
AmazonS3Client putObject: No content length specified for stream data. Stream contents will be buffered in memory and could result in out of memory errors.
Solution « Specify Object Metadata content Length
File tempFile = "D://Test.mp4";
String bucketName = "YashFiles", filePath = "local/mp4/";
FileInputStream sampleStream = new FileInputStream( tempFile );
byte[] byteArray = IOUtils.toByteArray( sampleStream );
Long contentLength = Long.valueOf(byteArray.length);
sampleStream.close();
ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentLength(contentLength);
TransferManager tm = new TransferManager(credentials);
FileInputStream stream = new FileInputStream( tempFile );
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, filePath, stream,objectMetadata);
Upload myUpload = tm.upload(putObjectRequest);
if (myUpload.isDone() == false) {
System.out.println("Transfer: "+ myUpload.getDescription());
System.out.println(" - State: "+ myUpload.getState());
System.out.println(" - Progress: "+ myUpload.getProgress().getBytesTransferred());
}
myUpload.waitForCompletion();
tm.shutdownNow();
stream.close();
org.apache.commons.io.FileUtils.forceDelete( tempFile );
