Hi I am new to spring integration, and I have the below code flow that read/scan files in the directory, I am encountering server error of too many files opened.. I am wondering if the below causing the issue?
Is the poller opening new file every time and not closing the previous files?
Thank you for the help.
@Bean
public IntegrationFlow jsonFileRefreshFlow(){
return IntegrationFlows.from(Files.inboundAdapter(new File(filePath))
.autoCreateDirectory(true)
.patternFilter("*.json")
.watchEvents(FileReadingMessageSource.WatchEventType.CREATE,
FileReadingMessageSource.WatchEventType.MODIFY)
.useWatchService(true)
.scanEachPoll(true)
.preventDuplicates(false)
e -> e.poller(Pollers.fixedDelay(1000, TimeUnit.MILLISECONDS)
.maxMessagesPerPoll(Integer.MAX_VALUE)))
.<File, Resource>transform(p -> new FileSystemResource(p))
.<Resource>handle((p,h) -> {
try{
// process payload
}catch (IOException ioEx){
log.error("Error refreshing json specs {}", ioEx);
}finally {
try {
p.getInputStream().close();
} catch (IOException e) {
log.error("error closing stream");
}
}
return null;
}).get();

The framework doesn't open the file; presumably your .handle() method does; so it is responsible for closing it.
