Marco Carletti updated CAMEL-23378:
-----------------------------------
Description:
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.
