因为摩托的设备登入方式是：ssh userName@IP，比其他设备的登入方式多了userName
(其他设备的登入方式，如华三：ssh IP),所以在用jsch连接的时候，不知道要从哪里注入userName
这个参数。
官网的例子代码如下：
package com.zzl;
/* -*-mode:java; c-basic-offset:2; indent-tabs-mode:nil -*- /
/*
public class Shell{
public static void main(String[] arg){
try{
JSch jsch=new JSch();
//jsch.setKnownHosts("/home/foo/.ssh/known_hosts");
String host=null;
if(arg.length>0){
host=arg[0];
}
else{
host=JOptionPane.showInputDialog("Enter username@hostname",
System.getProperty("user.name")+
"@localhost");
}
String user=host.substring(0, host.indexOf('@'));
host=host.substring(host.indexOf('@')+1);
Session session=jsch.getSession(user, host, 22);
String passwd = JOptionPane.showInputDialog("Enter password");
session.setPassword(passwd);
UserInfo ui = new MyUserInfo(){
public void showMessage(String message){
JOptionPane.showMessageDialog(null, message);
}
public boolean promptYesNo(String message){
Object[] options={ "yes", "no" };
int foo=JOptionPane.showOptionDialog(null,
message,
"Warning",
JOptionPane.DEFAULT_OPTION,
JOptionPane.WARNING_MESSAGE,
null, options, options[0]);
return foo==0;
}
// If password is not given before the invocation of Session#connect(),
// implement also following methods,
// * UserInfo#getPassword(),
// * UserInfo#promptPassword(String message) and
// * UIKeyboardInteractive#promptKeyboardInteractive()
};
session.setUserInfo(ui);
// It must not be recommended, but if you want to skip host-key check,
// invoke following,
// session.setConfig("StrictHostKeyChecking", "no");
//session.connect();
session.connect(30000); // making a connection with timeout.
Channel channel=session.openChannel("shell");
// Enable agent-forwarding.
//((ChannelShell)channel).setAgentForwarding(true);
channel.setInputStream(System.in);
/*
// a hack for MS-DOS prompt on Windows.
channel.setInputStream(new FilterInputStream(System.in){
public int read(byte[] b, int off, int len)throws IOException{
return in.read(b, off, (len>1024?1024:len));
}
});
*/
channel.setOutputStream(System.out);
/*
// Choose the pty-type "vt102".
((ChannelShell)channel).setPtyType("vt102");
*/
/*
// Set environment variable "LANG" as "ja_JP.eucJP".
((ChannelShell)channel).setEnv("LANG", "ja_JP.eucJP");
*/
channel.connect();
//channel.connect(3*1000);
}
catch(Exception e){
System.out.println(e);
}
