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"
