Standalone File Readers

If you have chosen not to use the declarative model, then you may choose to use Framework’s classes. The file reader is represented by the FileReadingMessageSource class. It implements Framework’s MessageSource interface with one method: receive(). This is a base interface implemented by all the sources that require polling for messages. The return value is a Message object with java.io.File as a payload.

The FileReadingMessageSource can be used as a simple bean to read the files as messages. The StandaloneFileAdapterTest below shows such a case. All you have to do is to instantiate the class and set a few properties, such as the directory in which you can find the files.
