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");
    }
}
