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
