This example demonstrates the following aspects of the File operations support available with Spring Integration:
1. File Inbound Channel Adapter
2. File Outbound Channel Adapter
3. File-to-Bytes Transformer
as well as Poller
The use case is a simple file copy, but implemented in 3 basic flavors:
1. Binary file copy
2. Text file copy
3. Simple file copy
To run samples simply execute the 3 test cases located in the org.springframework.integration.samples.filecopy package
