Java SSH远程执行Shell脚本实现

代码如下

代码语言：javascript复制

import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.Charset;

import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;

public class SshCommandExec {
  public static void exec(String ip, String command) {
    String username = "root";  //用户名
    String password = "admin01519";  //密码
    try {
      Connection conn = new Connection(ip);
      conn.connect();
      boolean isAuthenticated = conn.authenticateWithPassword(username,
          password);
      if (false == isAuthenticated) {
        throw new IOException("Authentication failed.");
      }
      Session session = conn.openSession();
      session.execCommand(command);

      String charset = Charset.defaultCharset().toString();
      InputStream stdOut = new StreamGobbler(session.getStdout());
      String outStr = processStream(stdOut, charset);

      InputStream stdErr = new StreamGobbler(session.getStderr());
      String errStr = processStream(stdErr, charset);

      System.out.println("stdErr:"   errStr);
      System.out.println("stdOut:"   outStr);

      session.close();
      conn.close();
    } catch (IOException e) {
      e.printStackTrace();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
  private static String processStream(InputStream in, String charset)
      throws Exception {
    byte[] buf = new byte[1024];
    StringBuilder sb = new StringBuilder();
    while (in.read(buf) != -1) {
      sb.append(new String(buf, charset));
    }
    return sb.toString();
  }
}
