我在Mule Studio（3.5）中安装了SSH连接器。
这是我的配置：

当我尝试运行流时，我在日志中得到以下异常：

我看到了连接器的代码，它正在使用net.schmizz.sshj库。我在java main中写了以下内容 -
SSHClient client = new SSHClient();
// client.addHostKeyVerifier("38:a3:94:7c:a9:78:19:2a:39:b2:89:f2:d1:86:2e:6a");
client.connect("server", 22);
client.authPassword("user", "password");
Session session = client.startSession();
Command cmd = null;
cmd = session.exec("pwd");
System.out.println(IOUtils.readFully(cmd.getInputStream()).toString());
cmd.close();
client.disconnect();
client.close();
当注释掉addHostKeyVerifier时，我得到相同的异常。当我取消注释它时，它可以工作。
但是，我没有在SSH连接器中看到我可以添加此主机密钥验证程序。
为什么我得到这个例外？这与我正在尝试连接的服务器有关吗？
谢谢，
阿迪
答案 0 :(得分：0)
当前版本的SSH连接器不允许添加单个主机密钥验证程序，但它会加载已知主机列表：
来自默认位置：
~/.ssh/known_hosts ~/.ssh/known_hosts2 您是否尝试在~/.ssh/known_hosts？
