SFTP Spring集成问题2 *用户名*

Question

的身份验证失败太多我们有一台SFTP服务器，我们正在读取该服务器上的文件特定文件夹。我使用基于用户/密码的身份验证是否需要在DefaultSftpSessionFactory中提供其他一些属性。 下面是我的配置。

<beans:bean id="sftpSessionFactory" 
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory"> 
    <beans:property name="host" value="${turboFtp.host}" /> 
    <beans:property name="allowUnknownKeys" value="true" /> 
    <beans:property name="user" value="${turboFtp.username}" /> 
    <beans:property name="password" 
     value="#{ftpdecrypter.decryptPassword()}" /> 
</beans:bean> 

<beans:bean id="ftpdecrypter" 
    class="com.deere.calibrateddevices.config.FTPPasswordDecryptConfig"> 
</beans:bean> 

<int-sftp:inbound-streaming-channel-adapter 
    id="sftpTurboHoneywellAdapter" channel="turboReceiveChannel" 
    session-factory="sftpSessionFactory" filename-regex="^.*\.(dat|DAT)$" 
    remote-file-separator="/" remote-directory-expression="'${turboXMLFileFtpServerLoc}'" 
    auto-startup="true"> 
    <int:poller fixed-rate="${turboPollarInterval}" 
     max-messages-per-poll="1" /> 
</int-sftp:inbound-streaming-channel-adapter> 

<int:channel id="sftpOutboundChannel" /> 

<int-sftp:outbound-gateway command="rm" 
    reply-channel="nullChannel" session-factory="sftpSessionFactory" 
    request-channel="sftpOutboundChannel" remote-file-separator="/" 
    expression="headers['file_remoteDirectory'] + headers['file_remoteFile']"> 
</int-sftp:outbound-gateway> 

<integration:service-activator id="calibratedDataServiceActivator" 
    input-channel="turboReceiveChannel" ref="turboFtpFileProcessor" 
    method="processTurboCalibratedDeviceFile" /> 

它的工作很好，但它间歇地给出了以下错误。

我不知道是什么造成这个issue.Is那里与SFTP SpringIntegration配置中的任何问题？我还需要提供DefaultSftpSessionFactory类中的一些其他属性？或者SFTP服务器有问题吗？ 任何人都可以指导我解决这个问题。

失败的原因是用户ID是在服务器上阻塞。释放后阻塞其工作正常。
