Elegant SpingBoot the asynchronous method invocation

Scene: Java call python, somewhat unstable, sometimes very fast, sometimes slow.

To ensure no contamination of the original code based on the asynchronous method call:

 Service Code:

public interface AsyncService {

    /**
     * 异步执行pathon
     * @param cmdArr
     * @return
     */
    void Async(String[] cmdArr);

}
import com.atage.op.service.AsyncService;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

/**
 * <p>
 *  服务实现类
 * </p>
 *
 * @author 鲁达
 * @since 2019-09-05
 */
@Service
public class AsyncServiceImpl implements AsyncService {

    @Async
    @Override
    public void Async(String[] cmdArr) {
        try {
            //要执行的业务代码
            Runtime.getRuntime().exec(cmdArr);
        }catch (Exception ex){
            ex.printStackTrace();
        }
    }
}

Controller Code:

类上加注解:@EnableAsync
@Autowired
private AsyncService asyncService;
调用:
try {
      asyncService.Async(cmdArr);
}catch(Exception e) {
      throw new RuntimeException("业务程序报错啦!!");
}
