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"
