Spring integration spring集成：sftp入站通道适配器主机的真实性'；x、 x.x.x'；can'；不能成立

我尝试使用以下代码下载文件：

<int-sftp:inbound-channel-adapter id="sftpInbondAdapter"
    auto-startup="true" channel="receiveChannel" session-factory="sftpSessionFactory"
    local-directory="file:${directory.files.local}" remote-directory="${directory.files.remote}"
    auto-create-local-directory="true" delete-remote-files="true"
    filename-pattern="*.txt">
    <int:poller fixed-delay="${sftp.interval.request}"
max-messages-per-poll="-1" error-channel="sftp.in.error.channel" />
</int-sftp:inbound-channel-adapter>

<bean id="defaultSftpSessionFactory"
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">

    <property name="host" value="${sftp.host}" />
    <property name="port" value="${sftp.port}" />
    <property name="user" value="${user}" />
    <property name="password" value="${password}" />
    <property name="allowUnknownKeys" value="true" />
</bean>

我也希望

org.springframework.integration

最后一条消息来自此代码

@Override
public boolean promptYesNo(String message) {
    logger.info(message);  // <<<<<<<<< INFO message in your log line 538
    if (hasDelegate()) {
        return getDelegate().promptYesNo(message);
    }
    else {
        if (logger.isDebugEnabled()) {
            logger.debug("No UserInfo provided - " + message + ", returning:"
                    + DefaultSftpSessionFactory.this.allowUnknownKeys);
        }
        return DefaultSftpSessionFactory.this.allowUnknownKeys;
    }
}

“Returning:false”表示

allowunknowkeys

属性是

false

，而不是配置中显示的

true

。也许您有另一个会话工厂bean覆盖了这个会话工厂？

请参阅我的编辑；不知何故，您正在使用的会话工厂没有将

allowunknowkeys

设置为true。

@Override
public boolean promptYesNo(String message) {
    logger.info(message);  // <<<<<<<<< INFO message in your log line 538
    if (hasDelegate()) {
        return getDelegate().promptYesNo(message);
    }
    else {
        if (logger.isDebugEnabled()) {
            logger.debug("No UserInfo provided - " + message + ", returning:"
                    + DefaultSftpSessionFactory.this.allowUnknownKeys);
        }
        return DefaultSftpSessionFactory.this.allowUnknownKeys;
    }
}
