Hi,
I am using polling consumer pattern to read all files in defined directory :
public List<GenericFile> scanFolder(String folder) {
List<GenericFile> result = new ArrayList<GenericFile>();
String endpointUrl = "file:////" + folder +
"?sendEmptyMessageWhenIdle=true&noop=true"
PollingConsumer pConsumer =
camelContext.getEndpoint(endpointUrl).createPollingConsumer();
pConsumer.start();
GenericFile<File> gFile;
do {
Exchange ex = pConsumer.receive(SCAN_TIMEOUT);
gFile = (GenericFile<File>) ex.getIn().getBody();
if(gFile != null) {
result.add(gFile);
}
} while(gFile != null); //empty message is sent when endpoint is idle
pConsumer.stop();
}
This works fine but as I am calling this method repeatedly Camel caches all
files in fileRepository (noop=true enforces idempotent=true) and result is
empty. I am using noop=true because this needs to work with read-only
filesystem. Is there a better way how to create 'folder scanner' using
polling consumer pattern which will read full folder content eachtime ?
