Claus Ibsen updated CAMEL-23378:
--------------------------------
Priority: Major (was: Critical)
> Block String to InputStream conversion in SpringTypeConverter
> -------------------------------------------------------------
>
> Key: CAMEL-23378
> URL: https://issues.apache.org/jira/browse/CAMEL-23378
> Project: Camel
> Issue Type: Bug
> Affects Versions: 4.18.2, 4.20.0
> Reporter: Marco Carletti
> Assignee: Marco Carletti
> Priority: Major
>
> When a Camel Spring Boot route writes a String body to a file: endpoint with
> checksumFileAlgorithm enabled, the body is incorrectly converted to a
> FileInputStream by Spring's ObjectToObjectConverter, which treats the String
> content as a file path:
> ConversionFailedException: Failed to convert from type [java.lang.String] to
> type [java.io.FileInputStream] for value [some file content] Caused by:
> FileNotFoundException: some file content (No such file or directory)
> This happens because the file component's checksum code path
> (FileOperations.java:321) calls
> exchange.getMessage().getBody(FileInputStream.class). On plain Camel this
> returns null (no matching converter) and falls through to the safe
> InputStream path. On Spring Boot, SpringTypeConverter delegates to Spring's
> GenericConversionService, which finds ObjectToObjectConverter. This converter
> sees the FileInputStream(String) constructor and calls new
> FileInputStream("some file content") — interpreting the message body as a
> file path instead of data.
