1,在pom中导入
<dependency> <groupId>ch.ethz.ganymed</groupId> <artifactId>ganymed-ssh2</artifactId> <version>build210</version> </dependency>
2,编写工具类
package org.jeecg.modules.system.util; /** * @Description: * @Author: LGX * @Date: 2020/11/19 10:36 */ import ch.ethz.ssh2.Connection; import ch.ethz.ssh2.Session; import ch.ethz.ssh2.StreamGobbler; import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor; import lombok.extern.slf4j.Slf4j; import org.apache.commons.lang.StringUtils; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import java.io.*; /** * 远程执行linux的shell script * @author Ickes * @since V0.1 */ @Data @NoArgsConstructor @AllArgsConstructor @Slf4j @Component public class RemoteExecuteCommandutil { //字符编码默认是utf-8 private static String DEFAULTCHART="UTF-8"; private Connection conn; @Value(value = "${jeecg.linux.ip}") public String ip; @Value(value = "${jeecg.linux.userName}") public String userName; @Value(value = "${jeecg.linux.userPwd}") public String userPwd; /** * 远程登录linux的主机 * @author Ickes * @since V0.1 * @return * 登录成功返回true,否则返回false */ public Boolean login(){ boolean flg=false; try { conn = new Connection(ip); conn.connect();//连接 flg=conn.authenticateWithPassword(userName, userPwd);//认证 } catch (IOException e) { e.printStackTrace(); } return flg; } /** * @author Ickes * 远程执行shll脚本或者命令 * @param cmd * 即将执行的命令 * @return * 命令执行完后返回的结果值 * @since V0.1 */ public String execute(String cmd){ String result=""; try { if(login()){ Session session= conn.openSession();//打开一个会话 session.execCommand(cmd);//执行命令 result=processStdout(session.getStdout(),DEFAULTCHART); //如果为得到标准输出为空,说明脚本执行出错了 if(StringUtils.isBlank(result)){ result=processStdout(session.getStderr(),DEFAULTCHART); } conn.close(); session.close(); } } catch (IOException e) { e.printStackTrace(); } return result; } /** * @author Ickes * 远程执行shll脚本或者命令 * @param cmd * 即将执行的命令 * @return * 命令执行成功后返回的结果值,如果命令执行失败,返回空字符串,不是null * @since V0.1 */ public String executeSuccess(String cmd){ String result=""; try { if(login()){ Session session= conn.openSession();//打开一个会话 session.execCommand(cmd);//执行命令 result=processStdout(session.getStdout(),DEFAULTCHART); conn.close(); session.close(); } } catch (IOException e) { e.printStackTrace(); } return result; } /** * 解析脚本执行返回的结果集 * @author Ickes * @param in 输入流对象 * @param charset 编码 * @since V0.1 * @return * 以纯文本的格式返回 */ private String processStdout(InputStream in, String charset){ InputStream stdout = new StreamGobbler(in); StringBuffer buffer = new StringBuffer();; try { BufferedReader br = new BufferedReader(new InputStreamReader(stdout,charset)); String line=null; while((line=br.readLine()) != null){ buffer.append(line+"\n"); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return buffer.toString(); } }
3,yml里编写配置信息
jeecg : linux: ip: 192.168.xxx.xxx userName: root userPwd: 123456
4,注入工具类,编写命令
@Autowired private RemoteExecuteCommandutil Commandutil; @GetMapping(value = "/training") public String training(@RequestParam(name="cmd") String cmd){ // String a = "sh /opt/shops/test1.sh 1 3"; //命令返回的信息 String cmdInformation =Commandutil.execute("source /etc/profile;"+cmd); return cmdInformation; }
由于ssh连接无法自动获取环境变量的值,得再执行前面加入source /etc/profile;来手动识别,如果还是不行可以在/etc/profile末尾加入export PATH="$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
