spring-integration - sftp:outbound-channel-adapter 拒绝 HostKey

Question

我正在尝试使用 Spring Integration sftp 出站 channel 适配器将文件发送到 sftp。

<int-sftp:outbound-channel-adapter id="sftpOutboundAdapter" session-factory="sftpSessionFactory"channel="sftpChannel" charset="UTF-8" remote-directory="/sftp/home/sftp_foler"  remote-filename-generator-expression="'dummy.txt'"/> 

我收到以下错误..

Caused by: java.lang.IllegalStateException: failed to connect
    at org.springframework.integration.sftp.session.SftpSession.connect(SftpSession.java:272)
    at org.springframework.integration.sftp.session.DefaultSftpSessionFactory.getSession(DefaultSftpSessionFactory.java:377)
    ... 42 more
Caused by: com.jcraft.jsch.JSchException: reject HostKey: myHost
    at com.jcraft.jsch.Session.checkHost(Session.java:791)
    at com.jcraft.jsch.Session.connect(Session.java:342)
    at com.jcraft.jsch.Session.connect(Session.java:183)
    at org.springframework.integration.sftp.session.SftpSession.connect(SftpSession.java:263)

我想，我可能必须将 StrictHostKeyChecking 设置为 no，但是如何在 sftp 出站网关中设置该值？ 请提出您的宝贵建议。

也许这个:

Previously, the DefaultSftpSessionFactory unconditionally allowed connections to unknown hosts. This is now configurable (default false).

The factory now requires a configured knownHosts file unless the allowUnknownKeys property is true (default false).
