我正在使用下面 Java 类中的Connect()方法，Ssh以便使用 SSH (JSch) 连接到服务器并在服务器中运行命令。
问题是在运行Connect()服务器时提示下一条消息：
Kerberos username [********]:
Kerberos password for ********:
为了继续运行，我需要手动按Enter两次键，一次输入用户名，一次输入密码。我试图添加下一个代码：
// Press ENTER
Robot r = new Robot();
r.keyPress(KeyEvent.VK_ENTER);
r.keyRelease(KeyEvent.VK_ENTER);
但是此代码仅适用于用户名，我不知道如何在服务器要求输入密码时自动按 ENTER。到目前为止，我已尝试将另一个代码片段放在上面显示的下方
session.connect();
线。
package ConnectSSH;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.io.*;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.UserInfo;
public class Ssh{
private static final String user = "********";
private static final String host = "********";
private static final Integer port = 22;
private static final String pass = "********";
public void Connect() throws Exception{
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, port);
UserInfo ui = new SUserInfo(pass, null);
session.setUserInfo(ui);
session.setPassword(pass);
//Press ENTER
Robot r = new Robot();
r.keyPress(KeyEvent.VK_ENTER);
r.keyRelease(KeyEvent.VK_ENTER);
session.connect();
ChannelExec channelExec = (ChannelExec)session.openChannel("exec");
InputStream in = channelExec.getInputStream();
channelExec.setCommand("RUN COMMAND");
channelExec.connect();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String linea = null;
int index = 0;
while ((linea = reader.readLine()) != null) {
System.out.println(++index + " : " + linea);
}
channelExec.disconnect();
session.disconnect();
}
}
这就是SUserInfo课堂
package ConnectSSH;
import com.jcraft.jsch.UserInfo;
public class SUserInfo implements UserInfo {
private String password;
private String passPhrase;
public SUserInfo (String password, String passPhrase) {
this.password = password;
this.passPhrase = passPhrase;
}
public String getPassphrase() {
return passPhrase;
}
public String getPassword() {
return password;
}
public boolean promptPassphrase(String arg0) {
return true;
}
public boolean promptPassword(String arg0) {
return false;
}
public boolean promptYesNo(String arg0) {
return true;
}
public void showMessage(String arg0) {
System.out.println("SUserInfo.showMessage()");
}
}
这就是记录器返回的内容：

然后它显示下一条消息
