Description

Camel aws2-s3 mutlipart upload only supports Files.

 

There are at least two approaches to solving this:

The hard, general case and a simple specific case.

 

1) The harder but general case: use something like Spring's aws SimpleStorageInputStream:

https://github.com/spring-cloud/spring-cloud-aws/blob/main/spring-cloud-aws-core/src/main/java/org/springframework/cloud/aws/core/io/s3/SimpleStorageResource.java

 and translate any exchange body to an Inputstream for mulitpart uploads.

 

2) The simpler but specific case: for remote files in particular, camel often makes use of a localwork directory to download files. In fact,

e.getIn().getBody(File.class) 

will resolve the file in the local work directory when polling from an FTP site with a local work directory specified.

 

The aws2-s3 producer (AWS2S3Producer.class) on lines 134 to 145 would need to be modified in both cases.
