java实现连接远程服务器并可以执行shell命令

你可以使用Java中的SSH库来连接远程服务器并执行shell命令。下面是一个简单的示例代码：

import com.jcraft.jsch.*;

public class SSHExample {
    public static void main(String[] args) {
        String host = "your_host";
        String username = "your_username";
        String password = "your_password";
        int port = 22;

        try {
            JSch jsch = new JSch();
            Session session = jsch.getSession(username, host, port);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no");
            session.connect();

            ChannelExec channel = (ChannelExec) session.openChannel("exec");
            channel.setCommand("your_shell_command");
            channel.connect();

            InputStream in = channel.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(in));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            channel.disconnect();
            session.disconnect();
        } catch (JSchException | IOException e) {
            e.printStackTrace();
        }
    }
}

请注意替换your_host，your_username，your_password和your_shell_command为实际的远程服务器信息和要执行的shell命令。该示例代码使用JSch库来建立SSH连接并执行命令。
