SFTP Spring集成问题2 *用户名*
问题描述:
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。SFTP Spring集成问题2 *用户名*
<beans:bean id="sftpSessionFactory"

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。
答
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。
检查[this](https://bugs.eclipse.org/bugs/show_bug.cgi?id=425672)是否适合您。 –
不是我面临FTPS的问题 –
SFTP和FTPS是完全不同的协议。 JSCH是一个SFTP库。您正在使用SFTP,而不是FTPS。 – Kenster
