骆驼SFTP，quartz2组件提供：无法检索文件：由GenericFileOperationFailedException，当从SFTP

轮询多个文件，我想用下面的骆驼航线，并使用quartz2调度，之后轮询几个文件的轮询从SFTP位置的文件，我“M得到一个GenricFileOperationFailedException caused by java.io.IOException: Pipe closed：骆驼SFTP，quartz2组件提供：无法检索文件：由GenericFileOperationFailedException，当从SFTP

JaxbDataFormat dataFormat = new JaxbDataFormat(); 
dataFormat.setContext(JAXBContext.newInstance(MyBean.class)); 

    from(sftphost + sourcedirpath + 
          "?password=" + password 
         + "&username=" + userName 
         + "&include=" + filePattern 
         + "&localWorkDirectory=" + localWorkingDirectory 
         + "&flatten=true" 
         + "&delete=true" 
         + "&scheduler=quartz2" 
         + "&scheduler.cron=0/45 * * * * ?" 
         + "&stepwise=false" 
         + "&disconnect=true") 
       .onException(Exception.class) 
        .to(sftphost + errdirpath + "?password=" + password + "&username=" + userName+"&disconnect=true") 
        .handled(true) 
        .end() 
       .log(LoggingLevel.INFO, "Processing File : ${file:onlyname}").log(LoggingLevel.INFO, "Before Unmarshalling XML").unmarshal(dataFormat) 
       .log(LoggingLevel.INFO, "after UnMarshalling the XML").beanRef("service", "processData(${body}, ${file:name})") 
       .to(sftphost + processedDirPAth + "?password=" + password + "&username=" + userName+ "&disconnect=true");

只有当我使用quartz2计划我面对这个问题。当我在骆驼路线中使用'& delay = 10000'参数时，上述骆驼路线完全正常。

我可以问你使用什么版本的骆驼？这个错误看起来对我来说很熟悉。 –

感谢您的回应。我使用的骆驼版本是2.15.2。 –

@RaminArabbagheri –

这看起来像是目标计算机上的SFTP用户的权限问题。请查阅https://winscp.net/eng/docs/sftp_codes#code_4了解更多详情。

它可能只是因为延迟而发生，因为SSL上下文未立即在Camel FTP2组件中配置/初始化，您需要在开始轮询之前延迟一小段时间。

感谢您的答复，我只得到这个问题时，我使用参数“调度= quartz2”，当我使用延迟参数“＆延迟= 15000”在mycamel路线我不明白这个问题。 –
