### 一.以springboot为例,建立代码 ###

**1.IExecCommandServer:**

public interface IExecCommandServer {
    
        void execCommand(String cmd);
    
    }

**2.ExecCommandServerImp:**

@Service
    public class ExecCommandServerImp implements IExecCommandServer {
    
        @Override
        public void execCommand(String cmd){
            try{
                Runtime rt = Runtime.getRuntime();
                Process proc = rt.exec(cmd,null,null);
                InputStream stderr =  proc.getInputStream();
                InputStreamReader isr = new InputStreamReader(stderr,"GBK");
                BufferedReader br = new BufferedReader(isr);
                String line="";
                while ((line = br.readLine()) != null) {
                    System.out.println(line);
                }
            }catch (Exception e){
                e.printStackTrace();
            }
        }
    }

**3.ExecCommandController:**

@CrossOrigin
    @RestController
    @RequestMapping("/linux")
    public class ExecCommandController {
    
        @Autowired
        private IExecCommandServer execCommandServer;
    
        @GetMapping("/exec")
        public ResultMap execCommand(String cmd) throws Exception {
            execCommandServer.execCommand(cmd);
                return Result.success("ok");
        }
    
    }

### 二,执行示例 ###

http://192.168.142.222:8086/linux/exec?cmd=ls /mnt
