JAVA远程执行Shell脚本类

1、java远程执行shell脚本类

 package com.test.common.utility;

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

 import org.apache.commons.io.IOUtils;
 import org.apache.commons.logging.Log;
 import org.apache.commons.logging.LogFactory;

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

 public class RmtShellExecutor {
     /** 远程机器IP */
     private final String ip;
     /** 用户名 */
     private final String usr;
     /** 密码 */
     private final String psword;

    /**
      * 构造函数
      *
      * @param ip
      * @param usr
      * @param ps
     */
     public RmtShellExecutor(String ip, String usr, String ps) {
         this.ip = ip;
         this.usr = usr;
         this.psword = ps;
     }

     /**
      * 执行脚本
      *
      * @param cmds
      * @return
      * @throws Exception
     */
     public int exec(String cmds) throws Exception {
         InputStream stdOut = null;
         InputStream stdErr = null;
         String outStr = "";
         String outErr = "";
         int ret = -1;
         try {
             if (login()) {
                 // Open a new {@link Session} on this connection
                 Session session = conn.openSession();
                 // Execute a command on the remote machine.
                 session.execCommand(cmds);
                 stdOut = new StreamGobbler(session.getStdout());
                 outStr = processStream(stdOut, charset);
                 stdErr = new StreamGobbler(session.getStderr());
                 outErr = processStream(stdErr, charset);
                 session.waitForCondition(ChannelCondition.EXIT_STATUS, TIME_OUT);
                 System.out.println("outStr=" + outStr);
                 System.out.println("outErr=" + outErr);
                 ret = session.getExitStatus();
             } else {
                 logger.info("登录远程机器失败" + ip);
                 throw new AppException("登录远程机器失败" + ip); // 自定义异常类 实现略
             }

         } finally {
             if (conn != null) {
                 conn.close();
             }
             IOUtils.closeQuietly(stdOut);
             IOUtils.closeQuietly(stdErr);

         }
         return ret;

     }

     private 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();

     }
 }

2、调用测试

         RmtShellExecutor exe = new RmtShellExecutor("10.190.1.123", "root", "root");
         try {
             int i = exe.exec("sh /dcdata/etl/runjobinfo/cscscs.sh");
             System.out.println(i);
         } catch (Exception e) {
             e.printStackTrace();
             logger.info("执行dsjob错误" + e.getMessage());
         }
