Spring Batch - Read files from Aws S3

Question

I am trying to read files from AWS S3 and process it with Spring Batch:

Can a Spring Itemreader process this Task? If so, How do I pass the credentials to S3 client

Answer 1

Another way to read from S3 through FlatFileItemReader is to set Resouce as InputStream Resouce and then use s3client putobject to upload the Stream.

reader.setResource(new InputStreamResouce(inputstream));

Once the stream is populated,

s3client.putObject(bucketname,key,inputstream,metadata);
