1.远程执行shell脚本类

package com.qingqing.bpt.utils.common;


import ch.ethz.ssh2.ChannelCondition;
import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;
import org.apache.commons.io.IOUtils;

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

        // 执行text.sh
        System.out.println(exe.exec("sh "+"/opt/xujd/text.sh "+params));
    }

}

2.shell脚本

#!/bin/bash
echo "Hello World XuJD!"
echo "第一个参数$1"  
echo "第二个参数$2" 

3.执行结果

Hello World XuJD!
第一个参数数学 
第二个参数语文
