使用springboot对linux进行操控的方法示例

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;




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.*;



@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;


  
  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;
  }
  
  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;
  }


  
  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;
  }

  
  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"
