Scheduling a function in Spring boot

Question

I am trying to schedule the following function to run every 10seconds. But it tells that it needs a void function. Is there any way to schedule the following function?

@Scheduled(fixedRate = 10000)
public FtpOutboundGateway getFiles() {
    FtpOutboundGateway gateway = new FtpOutboundGateway(sf(), "mget", "payload");
    gateway.setAutoCreateDirectory(true);
    gateway.setLocalDirectory(new File("./downloads/"));
    gateway.setFileExistsMode(FileExistsMode.REPLACE_IF_MODIFIED);
    gateway.setFilter(new AcceptOnceFileListFilter<>());
    gateway.setOutputChannelName("fileResults");
    return gateway;
}

Answer 1

For this, we need to do the following things.

1. First put this Annotation @EnableScheduling at the class level.
2. then at the function which needs to be scheduled should be marked with @Scheduled.
3. The function that we are trying to schedule should not return anything.

@EnableScheduling
class <ClassName>{
//def

 @Scheduled(fixedDelayString = "10000")
 public void fxnName() {
   //def
}

}
