Amazon web services – I am looking for io.awspring.cloud.s3.S3Resource as referred to in Spring Cloud AWS documentation

What issues do you have uploading an object using https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/s3/S3Client.html?

Using a product API is typically recommended over using a 3rd party API starting with support. The AWS SDK team will offer support and will not if you are using this 3rd party API.

If you setup your POM dependencies and setup your creds properly, the Java code works to upload an object. If you do not know how to setup the AWS SDK For Java V2, refer to this topic: Set up the AWS SDK for Java 2.x.

Full example to upload an object to an S3 bucket.
