rest api部署成功(部署了5场不同的战争（代码相同）
问题是，有数据库调用需要2分钟，我们得到502代理错误。
我增加了超时时间（在postman/代码httpconnection.settimeout中），但仍然出现以下错误：
Spring启动错误：

我甚至添加了事务超时，但没有成功
以下是代码：

@RestController
public class OfferingsService {
    @Autowired
    OfferingsRepository offeringsRepository;
    private static final Logger LOG = Logger.getLogger(OfferingsService.class.getName());

    @GetMapping("/offerings/all")
    @Transactional(timeout = 240000)
    public List<XxtoneOfferingsV> getAllOfferings(){
        LOG.info("getAllOfferings:");
        List<XxtoneOfferingsV> xxtoneOfferingsV = offeringsRepository.findAll();
        LOG.info("getAllOfferings: Size:" + xxtoneOfferingsV.size());
        return xxtoneOfferingsV;
    }
}

客户：

Log.info("RestURL1:" + URL);
    URL url = new URL(URL);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setConnectTimeout(240000);
    conn.setReadTimeout(240000);
    if (conn.getResponseCode() != 200 && conn.getResponseCode() != 404 ) {
           throw new RuntimeException("Failed : Error code : " + conn.getResponseCode());
    }

上面的代码在其他项目中是类似的，但数据库响应非常快。
