如何使用spring集成sftp出站网关从远程服务器下载文件？

我有 spring 批量设置（远程分区），它从文件中读取项目并处理它们 .

如果输入文件不存在，我想从远程服务器复制它们 . 所以我添加了一个步骤监听器，我试图使用spring integration sftp outbound gateway从远程服务器下载文件 .

public class PrepareExchangeListListener implements StepExecutionListener {

    private String localDir;
    private String remoteDir;

    private DirectChannel requestChannel;
    private PollableChannel replyChannel;

    public String getLocalDir() {
        return localDir;
    }

    public void setLocalDir(String localDir) {
        this.localDir = localDir;
    }

    public String getRemoteDir() {
        return remoteDir;
    }

    public void setRemoteDir(String remoteDir) {
        this.remoteDir = remoteDir;
    }

    public DirectChannel getRequestChannel() {
        return requestChannel;
    }

    public void setRequestChannel(DirectChannel requestChannel) {
        this.requestChannel = requestChannel;
    }

    public PollableChannel getReplyChannel() {
        return replyChannel;
    }

    public void setReplyChannel(PollableChannel replyChannel) {
        this.replyChannel = replyChannel;
    }

    @Override
    public void beforeStep(StepExecution stepExecution) {
        // TODO Auto-generated method stub

        System.out.println("Listener triggered.");

        this.requestChannel.send(new GenericMessage<Object>(this.remoteDir
                + "/" + "*"));

        Message<?> result = this.replyChannel.receive(100000);

        List<File> localFiles = (List<File>) result.getPayload();

        for (File file : localFiles) {

            System.out.println(file.getName());

        }

    }

    @Override
    public ExitStatus afterStep(StepExecution stepExecution) {

        return null;
    }

}

我指的是这个测试用例

    <listeners>
        <listener ref="prepareExchangeListListener" />
    </listeners>
    </step>
</job>

我做错了什么似乎没有任何效果 .

另外，int-sftp：outbound-gateway可以使用scope =“step”吗？如果我尝试添加，它会在STS中出错 .

    我建议你把事情分解成可管理的块 - 让SFTP的东西在一个独立的测试中工作;然后将它组装到你的工作中 .

    打开DEBUG日志记录以查看网关发生的情况 .

    不，您不能将Spring Integration组件放入 Step Scope中，您必须以编程方式或在子上下文中创建它，如（动态ftp示例）（https://github.com/spring-projects/spring-integration-samples/tree/master/advanced/dynamic-ftp）所示 .
