我有以下初始弹簧集成流程：

   final var inboundStreamingAdapter = Sftp.inboundStreamingAdapter(new SftpRemoteFileTemplate(sftpSessionFactory))
            .patternFilter("*.csv")
            .remoteDirectory(sftpRemoteDirectoryDownload);

   IntegrationFlows.from(inboundStreamingAdapter,c -> c.poller(Pollers.trigger(new PeriodicTrigger(10)).maxMessagesPerPoll(1)))
            .channel("data")
            .split(mySplitter)
            .get();

并且我的sftp服务器上有以下文件：

.DS_Store
PL_12002_1815_1.csv1

据我所知，适配器应该过滤掉所有以csv后缀结尾的内容。

实际发生的情况是，某些文件（.DS_Store）有时会根据当前存储在FTP上的内容进入mySplitter。

据我所知问题出在AbstractRemoteFileStreamingMessageSource（用作SftpStreamingMessageSource类的基类）中：

           if (this.filter != null && this.filter.supportsSingleFileFiltering()
                       && !this.filter.accept(file.getFileInfo())) {  //HERE APPLY A FILTER AND FIND OUT PL_12002_1815_1.csv1 SHOULD NOT BE PROCESSED

                   if (this.tobereceived.size() > 0) { // don't re-fetch already filtered files 
                       //HERE WE LOAD ANOTHER FILE FROM THE QUEUE (.DS_Store)
                       file = poll();
                   }
                   else {
                       file = null;
                   }
           }
    //FILTER IS NOT REAPPLIED FURTHER DOWN AND WE CREATE A MESSAGE FOR .DS_Store
           if (file != null) {
               try {
                   String remotePath = remotePath(file);
                   Session<?> session = this.remoteFileTemplate.getSession();
                   try {
                       return getMessageBuilderFactory()
                               .withPayload(session.readRaw(remotePath))
                               .setHeader(IntegrationmessageHeaderaccessor.CLOSEABLE_RESOURCE,session)
                               .setHeader(FileHeaders.REMOTE_DIRECTORY,file.getRemoteDirectory())
                               .setHeader(FileHeaders.REMOTE_FILE,file.getFilename())
                               .setHeader(FileHeaders.REMOTE_HOST_PORT,session.getHostPort())
                               .setHeader(FileHeaders.REMOTE_FILE_INFO,this.fileInfoJson ? file.toJson() : file);
       }

我会说这是一个错误，但是也许我只是配置错误，有人可以帮忙吗？
