SFTP集成JSCH - 无法在会话上执行

时间：2014-07-26 03:00:43

标签： java spring spring-integration jsch

我的Spring Integration示例程序使用我的Mac设置作为本地SFTP服务器（只是as here）一切正常。我尝试用实际（我们的客户端/提供商的）SFTP凭证替换我的测试凭证，Spring Integration在JSCH模块中给出了以下异常。我实际上能够连接到此服务器并使用Filezilla浏览目录。

任何指针都会有很大的帮助。会话创建几乎是常见的方式：

<bean id="sftpSessionFactory" class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="${host}"/>
    <property name="port" value="${port}"/>
    <property name="user" value="${user}"/>
    <property name="password" value="${password}"/>
</bean>

这是日志：

答案 0 :(得分：2)

我不知道该告诉你什么;你肯定凭据是否正确？它必须简单。

如果我使用...... 

<bean id="sftpSessionFactory"
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="myserver"/>
    <property name="port" value="22"/>
    <property name="user" value="ftptest"/>
    <property name="password" value="ftptest"/>
</bean>

我没有问题。

如果我将其更改为...... 

<bean id="sftpSessionFactory"
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="myserver"/>
    <property name="port" value="22"/>
    <property name="user" value="ftptest"/>
    <property name="password" value="junk"/>
</bean>

...我得到与你完全相同的结果。

Caused by: com.jcraft.jsch.JSchException: SSH_MSG_DISCONNECT: 2 Too many authentication failures for ftptest

在服务器（tail -f /var/log/auth.log）上，我看到6次尝试连接错误的密码。

您应该考虑使用公钥/私钥 - 无论如何它都更安全。

编辑：

您可以通过添加配置属性来阻止回退并仅尝试使用密码身份验证... 

<util:properties id="props">
    <prop key="PreferredAuthentications">password</prop>
</util:properties>

<bean id="sftpSessionFactory"
    class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="10.0.0.3"/>
    <property name="port" value="22"/>
    <property name="user" value="ftpTest"/>
    <property name="password" value="ftpTest"/>
    <property name="sessionConfig" ref="props" />
</bean>
