朝阳网站建设是什么怎么创建自己的游戏网站

1. 使用JDK自带的RunTime类和Process类实现

public static void main(String[] args){Process proc = RunTime.getRunTime().exec("cd /home/tom; ls;")// 标准输入流（必须写在 waitFor 之前）String inStr = consumeInputStream(proc.getInputStream());// 标准错误流（必须写在 waitFor 之前）String errStr = consumeInputStream(proc.getErrorStream());int retCode = proc.waitFor();if(retCode == 0){System.out.println("程序正常执行结束");}
}/***   消费inputstream，并返回*/
public static String consumeInputStream(InputStream is){BufferedReader br = new BufferedReader(new InputStreamReader(is));String s ;StringBuilder sb = new StringBuilder();while((s=br.readLine())!=null){System.out.println(s);sb.append(s);}return sb.toString();
}

2. ganymed-ssh2 实现

pom

<!--ganymed-ssh2包-->
<dependency><groupId>ch.ethz.ganymed</groupId><artifactId>ganymed-ssh2</artifactId><version>build210</version>
</dependency>

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;public static void main(String[] args){String host = "210.38.162.181";int port = 22;String username = "root";String password = "root";// 创建连接Connection conn = new Connection(host, port);// 启动连接conn.connection();// 验证用户密码conn.authenticateWithPassword(username, password);Session session = conn.openSession();session.execCommand("cd /home/winnie; ls;");// 消费所有输入流String inStr = consumeInputStream(session.getStdout());String errStr = consumeInputStream(session.getStderr());session.close;conn.close();
}/***   消费inputstream，并返回*/
public static String consumeInputStream(InputStream is){BufferedReader br = new BufferedReader(new InputStreamReader(is));String s ;StringBuilder sb = new StringBuilder();while((s=br.readLine())!=null){System.out.println(s);sb.append(s);}return sb.toString();
}

3. jsch实现

pom

<dependency><groupId>com.jcraft</groupId><artifactId>jsch</artifactId><version>0.1.55</version>
</dependency>

import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;public static void main(String[] args){String host = "210.38.162.181";int port = 22;String username = "root";String password = "root";// 创建JSchJSch jSch = new JSch();// 获取sessionSession session = jSch.getSession(username, host, port);session.setPassword(password);Properties prop = new Properties();prop.put("StrictHostKeyChecking", "no");session.setProperties(prop);// 启动连接session.connect();ChannelExec exec = (ChannelExec)session.openChannel("exec");exec.setCommand("cd /home/winnie; ls;");exec.setInputStream(null);exec.setErrStream(System.err);exec.connect();// 消费所有输入流，必须在exec之后String inStr = consumeInputStream(exec.getInputStream());String errStr = consumeInputStream(exec.getErrStream());exec.disconnect();session.disconnect();
}/***   消费inputstream，并返回*/
public static String consumeInputStream(InputStream is){BufferedReader br = new BufferedReader(new InputStreamReader(is));String s ;StringBuilder sb = new StringBuilder();while((s=br.readLine())!=null){System.out.println(s);sb.append(s);}return sb.toString();
}
