Have a spring integration application where files are routed from a folder to S3 buckets using s3-outbound-channel-adapter. I need to know the number of files/object that are stored under S3 bucket for today's date(current date) and files having format (csv/txt) alone.

Would like to know how to get it using spring-integration-aws without using aws-sdk directly?

Observed that spring-integration-aws has a method in S3session.

@Override
    public S3ObjectSummary[] list(String path) throws IOException {
}

Do we need to use comparator on S3ObjectSummary or is there any other method available to achieve this. Any suggestion is helpful.

So, you use S3Session.listNames() and then filter result for desired file extensions.

If you really need some more comprehensive logic, you can consider to use a S3RemoteFileTemplate and its executeWithClient() to access a low-level AWS API.
