java.io.IOException：在WebLogic服务器上使用AsyncRestTemplate时对等方重置连接

java.io.IOException: Connection reset by peer#39; when using AsyncRestTemplate on weblogic server(java.io.IOException：在WebLogic服务器上使用AsyncRestTemplate时对等方重置连接)

问题描述

我的Springboot应用程序部署在我的VP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，返回此错误：

我注意到只有在使用Springs AsyncRestTemplate调用API调用时才会出现这种情况。

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();
    }

推荐答案

错误

Connection reset by peer

是远程服务器(或它们之间的防火墙)发出的响应，声明它将不会继续完成此请求。

很可能是防火墙拒绝、SSL握手失败、代理问题，甚至是HTTP失败的请求。
