I need to set filename & timestamp of a file using sftpoutputgateway object. How do i do it ? I know it will be done through Spel language ,but not sure what the systax looks like.

CodePudding user response：

it would be better to just use the SftpRemoteFileTemplate directly in your code.

something like this way.

template.rename(...);
template.get(pathToFile, inputStream -> ...);
template.rename(...); // or template.remove(...);

for timestamp,

 @Bean
    public IntegrationFlow sftpInboundFlow() {
        return IntegrationFlows
            .from(Sftp.inboundAdapter(this.sftpSessionFactory)
                    .preserveTimestamp(true)
                    .remoteDirectory("foo")
                    .regexFilter(".*\\.txt$")
                    .localFilenameExpression("#this.toUpperCase()   '.a'")
                    .localDirectory(new File("sftp-inbound")),
                 e -> e.id("sftpInboundAdapter")
                    .autoStartup(true)
                    .poller(Pollers.fixedDelay(5000)))
            .handle(m -> System.out.println(m.getPayload()))
            .get();
    }
}

you can also refer to this documentation

Setting timestamp on the remote file is not a gateway responsibility.

See SftpRemoteFileTemplate.executeWithClient(ClientCallback<C, T> callback):

        public void handleMessage(Message<?> message) throws MessagingException {
            String remoteFile = (String) message.getPayload();
            Integer newModTime = message.getHeaders().get("newModTime", Integer.class);
            
            template.executeWithClient((ClientCallbackWithoutResult<ChannelSftp>) client -> {
                try {
                    SftpATTRS attrs = client.lstat(remoteFile);
                    attrs.setACMODTIME(attrs.getATime(), newModTime);
                    client.setStat(remoteFile, attrs);
                }
                catch (SftpException e) {
                    throw new RuntimeException(e);
                }
            });
        }

This one can be used in a service activator method where you get access to the Message.
