使用发布订阅，我将本地文件推送到多个远程文件夹（remoteDirectory1，remoteDirectory2（复制到远程成功和存档文件夹）） 同时，我需要删除另一个remoteDirectory3中的相同文件（例如：从远程处理文件夹中删除）
使用下面的代码代码，我可以将文件传输到远程，但不能删除另一个远程目录中的文件。
我对SPEL表达式感到困惑，无法在outboundGateway中表达...
private IntegrationFlow pushRemoteFolder(final String localDirectory, String remoteDirectory1, String remoteDirectory2,String remoteDirectory3,String adapterName, String filePattern, String fileRenameExpression) {
return IntegrationFlows
.from(Files.inboundAdapter(Paths.get(localDirectory).toFile())
.regexFilter(filePattern)
.preventDuplicates(false),
e -> {
e.poller(Pollers.fixedDelay(SftpProperties.getPollerIntervalMs())
.maxMessagesPerPoll(SftpProperties.getMaxFetchSize())
.errorChannel("errorChannel")
.transactional(transactionManager)
.transactionSynchronizationFactory(PushSftpSyncFactory()) // moves processed files
).id(adapterName);
})
.publishSubscribeChannel(s -> s
.subscribe(f -> f
.handle(Sftp.outboundAdapter(PushSftpSessionFactory())
.remoteDirectory(sftpProperties.getRemoteRootDir() + remoteDirectory1)
.fileNameExpression(fileRenameExpression) //.fileNameExpression("payload.getName().replace('A','B')")
.temporaryFileSuffix(".tmp")))
.subscribe(f -> f
.handle(Sftp.outboundAdapter(PushSftpSessionFactory())
.remoteDirectory(sftpProperties.getRemoteRootDir() + remoteDirectory2)
.fileNameExpression(fileRenameExpression)
.temporaryFileSuffix(".tmp")))
.subscribe(f -> f
.handle(Sftp.outboundGateway(PushSftpSessionFactory()
,AbstractRemoteFileOutboundGateway.Coand.RM
,"'" + mmSftpProperties.getRemoteRootDir() + remoteDirectory3 + "/' + payload.name")))
).get();
}
字符串的值
sftpProperties.getRemoteRootDir() = > /home/hari，
remoteDirectory3 = /Sample/Processing
....
我认为我在表达式中缺少文件名
如果我给定硬代码值“'/home/hari/Sample/Processing/sample.xml'”，它将删除文件，但我没有得到回复频道错误
遇到以下错误

在问这样的问题时，请提供版本信息；必须仔细查看所有版本以排列行号是很痛苦的。
此表达式<div id="order-countdown" data-orderstart="09.22" data-orderexpiry="17.15">
<div class="countdown hidden"><span class="time">00:00:00</span></div>
</div>
不是表达式；它需要变成一个文字
$(function(){
initCutoffTimer(["1","2","3","4","5"]) //array with days to show timer
});
function initCutoffTimer(showDays){
var dt = new Date(),
time = dt.getHours(),
year = dt.getFullYear(),
month = dt.getMonth()+1,
day = dt.getDate(),
dayNr = dt.getDay(),
currentDate = dt.getFullYear() + '/' + (month < 10 ? '0' : '') + month + '/' + (day < 10 ? '0' : '') + day,
$.each(showDays, function(index, showDay){
showDay = showDay.trim();
showDay = parseInt(showDay);
var showCountdownTill = parseInt($('#order-countdown').data('orderexpiry'));
var showCountdownFrom = parseInt($('#order-countdown').data('orderstart'));
if(dayNr == showDay && time >= showCountdownFrom) {
$('#order-countdown .countdown .time').countdown(currentDate +' '+showCountdownTill+':00')
.on('update.countdown', function(event) {
var format = '%-H:%M:%S';
$(this).html(event.strftime(format));
$('#order-countdown .countdown').removeClass('hidden');
}).on('finish.countdown', function(event) {
$('#order-countdown .countdown').addClass('hidden');
});
}
});
}
