java本地调用cmd，shell命令，远程调用Linux执行命令方法总结

部署远程服务器的时候会用到，之前做过类似的项目，逛首页的时候又看到了，记录一下。

有时候经常会碰到需要远程调用Linux或者本地调用Linux或者本地调用cmd的一些命令，最近小结了一下这几种用法。

本地调用cmd命令

package com.cn.cmd;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;public class testCmd {public void testCmd(){String cmd = "cmd /c date";execCmd(cmd);}private void execCmd(String cmd) {// TODO Auto-generated method stubRuntime rt = Runtime.getRuntime();try {Process proc = rt.exec(cmd,null,null);InputStream stderr = proc.getInputStream();InputStreamReader isr = new InputStreamReader(stderr,"GBK");BufferedReader br = new BufferedReader(isr);String line = "";while((line = br.readLine()) != null){System.out.println(line);}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public static void main(String[] args) {// TODO Auto-generated method stub        testCmd tc = new testCmd();        tc.testCmd();}}

本地调用Linux命令

@Test    public void testCmd()throws Exception{        String cmd="/bin/sh -c date"; //命令的前面必须要有/bin/sh -c        execCmd(cmd);    }    public static void execCmd(String cmd){        try{            Runtime rt = Runtime.getRuntime();            //执行命令, 最后一个参数，可以使用new File("path")指定运行的命令的位置            Process proc = rt.exec(cmd,null,null);              InputStream stderr =  proc.getInputStream();            InputStreamReader isr = new InputStreamReader(stderr,"GBK");            BufferedReader br = new BufferedReader(isr);            String line="";            while ((line = br.readLine()) != null) { // 打印出命令执行的结果                System.out.println(line);            }        }catch (Exception e){            e.printStackTrace();        }    }

远程调用Linux执行命令

1.

jar包下载

http://central.maven.org/maven2/com/jcraft/jsch/0.1.54/jsch-0.1.54.jar

2.

或者maven引用

<dependency>    <groupId>com.jcraft</groupId>    <artifactId>jsch</artifactId>    <version>0.1.54</version></dependency>

3.源代码如下

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import com.jcraft.jsch.ChannelExec;import com.jcraft.jsch.JSch;import com.jcraft.jsch.JSchException;import com.jcraft.jsch.Session;public class SSHHelper {    /**     * 远程 执行命令并返回结果调用过程 是同步的（执行完才会返回）     * @param host  主机名     * @param user  用户名     * @param psw   密码     * @param port  端口     * @param command   命令     * @return     */    public static String exec(String host,String user,String psw,int port,String command){        StringBuffer sb= new StringBuffer();        Session session =null;        ChannelExec openChannel =null;        try {            JSch jsch=new JSch();            session = jsch.getSession(user, host, port);            java.util.Properties config = new java.util.Properties();            config.put("StrictHostKeyChecking", "no");//跳过公钥的询问            session.setConfig(config);            session.setPassword(psw);            session.connect(5000);//设置连接的超时时间            openChannel = (ChannelExec) session.openChannel("exec");            openChannel.setCommand(command); //执行命令            int exitStatus = openChannel.getExitStatus(); //退出状态为-1，直到通道关闭            System.out.println(exitStatus);            // 下面是得到输出的内容            openChannel.connect();            InputStream in = openChannel.getInputStream();            BufferedReader reader = new BufferedReader(new InputStreamReader(in));            String buf = null;            while ((buf = reader.readLine()) != null) {                sb.append(buf+"\n");            }        } catch (JSchException | IOException e) {            sb.append(e.getMessage()+"\n");        }finally{            if(openChannel!=null&&!openChannel.isClosed()){                openChannel.disconnect();            }            if(session!=null&&session.isConnected()){                session.disconnect();            }        }        return sb.toString();    }    public static void main(String args[]){        String exec = exec("192.168.1.xx", "user", "name", 22, "ls");        System.out.println(exec);    }}
