AWS S3 JAVA SDK-listObjects返回不完整的目录列表

Question

When i use the listObjects() method, AWS returns a list of files and folders similar to this:

root/
root/projects/
root/projects/101/
root/projects/102/
root/projects/102/file1.pdf
root/images/image1.png
root/images/image2.png
root/favicon.ico

My results are not being truncated, and I'm wondering why it doesn't return a record for root/images/ I am not using the delimiter feature.

Answer 1

If You use as following, The List Object will have all the objects in the S3 Bucket. ListObjectsRequest lor = new ListObjectsRequest().withBucketName("myBucket"); ObjectListing objectListing = s3.listObjects(lor);

If you want to have only objects in a specified directory as you said root/images, you need to specify as

ListObjectsRequest lor = new ListObjectsRequest().withBucketName("myBucket").withPrefix("image/");

Hope it helps
