接着上篇http://blog.csdn.net/doctor_who2004/article/details/47322105的介绍：
我们模拟下putty这类交互式的执行远程命令：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.nio.charset.StandardCharsets;
import java.util.Scanner;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;
import org.apache.commons.io.IOUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;

public final class SSHAgent2 {
private Logger log = LoggerFactory.getLogger(getClass());
private Connection connection;
private Session session;
private BufferedReader stdout;
private PrintWriter printWriter;
private BufferedReader stderr;
private ExecutorService service = Executors.newFixedThreadPool(3);
private Scanner scanner = new Scanner(System.in);
public void initSession(String hostName, String userName, String passwd) throws IOException {
connection = new Connection(hostName);
connection.connect();
boolean authenticateWithPassword = connection.authenticateWithPassword(userName, passwd);
if (!authenticateWithPassword) {
throw new RuntimeException("Authentication failed. Please check hostName, userName and passwd");
}
session = connection.openSession();
session.requestDumbPTY();
session.startShell();
stdout = new BufferedReader(new InputStreamReader(new StreamGobbler(session.getStdout()), StandardCharsets.UTF_8));
stderr = new BufferedReader(new InputStreamReader(new StreamGobbler(session.getStderr()), StandardCharsets.UTF_8));
printWriter = new PrintWriter(session.getStdin());
}
public void execCommand() throws IOException {
service.submit(new Runnable() {
@Override
public void run() {
String line;
try {
while ((line = stdout.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
});
service.submit(new Runnable() {
@Override
public void run() {
while (true) {
try {
TimeUnit.SECONDS.sleep(1);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.print("input:");
String nextLine = scanner.nextLine();
printWriter.write(nextLine + "\r\n");
printWriter.flush();
}
}
});
}
public void close() {
IOUtils.closeQuietly(stdout);
IOUtils.closeQuietly(stderr);
IOUtils.closeQuietly(printWriter);
IOUtils.closeQuietly(scanner);
session.close();
connection.close();
}
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
SSHAgent2 sshAgent = new SSHAgent2();
sshAgent.initSession("127.0.0.1", "doctor", "xxxx");
sshAgent.execCommand();
// sshAgent.close();
}
}
这里读写流我分别在不同线程下操作，防止读写流之间的阻塞，简单模拟交互环境。当然，登陆的是本地系统，没有安装虚拟机等。
执行结果：
