怎么在java中执行sudo 命令

本篇内容介绍了"怎么在java中执行sudo 命令"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

 *    1. 修改/etc/sudoers文件，在其中添加一行： *          username  ALL=(ALL) NOPASSWD:ALL *       其中，"username"是需要运行这个程序的用户名。

 /bin/bash -c echo password |sudo -S command

Shell（JSCH）工具类：

package cn.bywin.cbvsp.common.utils;import cn.bywin.cbvsp.DAL.BO.po.MyUserInfo;import com.jcraft.jsch.*;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.util.ArrayList;/** * @author linbin * @create 2019-03-19 10:06 */public class Shell {    //远程主机的ip地址    private String ip;    //远程主机登录用户名    private String username;    //远程主机的登录密码    private String password;    //设置ssh连接的远程端口    public static final int DEFAULT_SSH_PORT = 22;    //保存输出内容的容器    private ArrayList stdout;    public Shell() {    }    /**     * 初始化登录信息     *     * @param ip     * @param username     * @param password     */    public Shell(final String ip, final String username, final String password) {        this.ip = ip;        this.username = username;        this.password = password;        stdout = new ArrayList();    }    /**     * 执行shell命令     *     * @param command     * @return     */    //原本是 execute(final String command)    public int execute(String command) {        int returnCode = 0;        JSch jsch = new JSch();        MyUserInfo userInfo = new MyUserInfo();        try {            //创建session并且打开连接，因为创建session之后要主动打开连接            Session session = jsch.getSession(username, ip, DEFAULT_SSH_PORT);            session.setPassword(password);            session.setUserInfo(userInfo);            session.connect();            //打开通道，设置通道类型，和执行的命令            Channel channel = session.openChannel("exec");            ChannelExec channelExec = (ChannelExec) channel;            channelExec.setCommand(command);            channelExec.setInputStream(null);            BufferedReader input = new BufferedReader(new InputStreamReader                    (channelExec.getInputStream()));            channelExec.connect();            System.out.println("The remote command is :" + command);            //接收远程服务器执行命令的结果            String line;            while ((line = input.readLine()) != null) {                stdout.add(line);            }            input.close();            // 得到returnCode            if (channelExec.isClosed()) {                returnCode = channelExec.getExitStatus();                // 关闭通道                channelExec.disconnect();                //关闭session                session.disconnect();            }        } catch (JSchException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (Exception e) {            e.printStackTrace();        }        return returnCode;    }    public static ChannelExec getCommandResult(Session session, String command) throws JSchException, IOException {        ChannelExec channelExec = (ChannelExec) session.openChannel("exec");        channelExec.setCommand(command);        channelExec.setInputStream(null);        channelExec.setErrStream(System.err);        channelExec.connect();        /*if (null != session) {            session.disconnect();        }*/        return channelExec;    }    /**     * get stdout     *     * @return     */    public ArrayList getStandardOutput() {        return stdout;    }}

执行代码：

    public static void main(String[] args) {        Shell shell = new Shell("192.168.161.152","root","linbinbhs7");        shell.execute("/bin/bash -c echo linbinbhs7 |sudo -S ls");        ArrayList graphicsCardNames = shell.getStandardOutput();        graphicsCardNames.forEach(e->{            System.out.println(e);        });    }

删除指定时间的文件

public class TestShell {    public static void main(String[] args) {        Shell shell = new Shell("192.168.96.136","developer","de183!!!");        shell.execute("/bin/bash -c echo de183!!! |sudo -S find /home/developer/temp -type f -mmin +1 -exec rm -rfv {} \\; > /home/developer/temp/nohup.out;");        ArrayList graphicsCardNames = shell.getStandardOutput();        graphicsCardNames.forEach(System.out::println);    }}
