java编写连接linux代码

使用jsch连接linux，下载jsch包或者使用maven

<dependencies><dependency><groupId>com.jcraft</groupId><artifactId>jsch</artifactId><version>0.1.55</version></dependency></dependencies>

新建maven项目，或者选择项目右键把项目转化为maven项目
在src/main/java下，新建包，输入com.tools
在包下创建JschDemo类，代码如下：

package com.tools;import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelExec;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;import java.io.InputStream;
public class JschDemo {public static void executeCommand(String host, String user, String password, String command) {try {JSch jsch = new JSch();Session session = jsch.getSession(user, host, 22);session.setPassword(password);session.setConfig("StrictHostKeyChecking", "no");session.connect();Channel channel = session.openChannel("exec");((ChannelExec) channel).setCommand(command);channel.setInputStream(null);((ChannelExec) channel).setErrStream(System.err);InputStream in = channel.getInputStream();channel.connect();byte[] tmp = new byte[1024];while (true) {while (in.available() > 0) {int i = in.read(tmp, 0, 1024);if (i < 0) break;System.out.print(new String(tmp, 0, i));}if (channel.isClosed()) {if (in.available() > 0) continue;System.out.println("exit-status: " + channel.getExitStatus());break;}try {Thread.sleep(1000);} catch (Exception ee) {}}channel.disconnect();session.disconnect();} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {JschDemo jschDemo = new JschDemo();jschDemo.executeCommand("xxxxx,  "root", "xxxx","date -s \"2023-5-22 14:26\"");jschDemo.executeCommand("xxxxx",  "root", "xxxx","ls");}
}
