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;/** * 模拟交互式终端 *  * @author doctor * * @time 2015年8月6日   * * @see http://www.programcreek.com/java-api-examples/index.php?api=ch.ethz.ssh2.SCPClient * */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() {@Overridepublic void run() {String line;try {while ((line = stdout.readLine()) != null) {System.out.println(line);}} catch (IOException e) {e.printStackTrace();}}});service.submit(new Runnable() {@Overridepublic 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：
