java 远程调用shell脚本demo

首先在远程服务器上编写一个测试脚本test.sh,并赋予可执行权限：chmod +x test.sh

#!/bin/bashecho 'test22'echo $1

$1是脚本传进来的第一个参数，我们控制台打印一下这个参数

新建maven项目，添加依赖：

<dependency><groupId>org.jvnet.hudson</groupId><artifactId>ganymed-ssh2</artifactId><version>build210-hudson-1</version></dependency>

编写一个工具类：

package com.xj.runshell;import java.io.IOException;import java.io.InputStream;import java.nio.charset.Charset;import ch.ethz.ssh2.Connection;import ch.ethz.ssh2.Session;public class RemoteShellTool {private Connection conn;private String ipAddr;private String charset = Charset.defaultCharset().toString();private String userName;private String password;public RemoteShellTool(String ipAddr, String userName, String password,String charset) {this.ipAddr = ipAddr;this.userName = userName;this.password = password;if (charset != null) {this.charset = charset;}}public boolean login() throws IOException {conn = new Connection(ipAddr);conn.connect(); // 连接return conn.authenticateWithPassword(userName, password); // 认证}public String exec(String cmds) {InputStream in = null;String result = "";try {if (this.login()) {Session session = conn.openSession(); // 打开一个会话session.execCommand(cmds);in = session.getStdout();result = this.processStdout(in, this.charset);session.close();conn.close();}} catch (IOException e1) {e1.printStackTrace();}return result;}public String processStdout(InputStream in, String charset) {byte[] buf = new byte[1024];StringBuffer sb = new StringBuffer();try {while (in.read(buf) != -1) {sb.append(new String(buf, charset));}} catch (IOException e) {e.printStackTrace();}return sb.toString();}/** * @param args */public static void main(String[] args) {RemoteShellTool tool = new RemoteShellTool("192.168.27.41", "hadoop","hadoop", "utf-8");String result = tool.exec("./test.sh xiaojun");System.out.print(result);}}

main函数中执行了./test.sh xiaojun这个命令，控制台打印出：

test22

xiaojun

这个简单的远程调用shell demo就算完了。
