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());
        }
