java.io.IOException : Connection reset by peer' when using AsyncRestTemplate on weblogic server

Question

我的 Springboot 应用程序部署在位于我的 vps 上的 weblogic 服务器上，当我运行打算调用另一个网站的 API 方法的方法时，我返回此错误:

我注意到，只有当我使用 Springs AsyncRestTemplate 调用 API 调用时才会发生这种情况。

ListenableFuture<ResponseEntity<String>> y = asyncRestTemplate.exchange(desiredUrl, HttpMethod.GET, new HttpEntity<>("result"), String.class);//.get().getBody();
       boolean done = false;
        while (done == false)
        {
            if (y.isDone() == true)
            {
            response = y.get().getBody();
                        return response;
            }

        } 

    } catch (InterruptedException | ExecutionException ex) {

        Logger.getLogger(HTTP_Methods.class.getName()).log(Level.SEVERE, null, ex);
        ex.printStackTrace();
    }

错误

Connection reset by peer

是远程服务器(或它们之间的防火墙)的响应，表明它将不会继续完成此请求。

这很可能是防火墙拒绝、SSL 握手失败、代理问题甚至 HTTP 请求失败。
