我试图用Spring Rest Template发送一个POST请求到某个URL，得到java.net.SocketException。连接重置。
这是实际执行的代码。
ResponseEntity<Void> response = restOperations.exchange(eventLoggingHost, HttpMethod.POST, httpEntity, Void.class);
我得到了以下异常。

我读过一些关于封闭式套接字的文章，但我没有在这个层面上操作这些概念。
原来是一些大IP服务在网络层面设置了请求超时。我们只好要求维护工程师增加超时时间，以预留我们请求处理的时间。
当然，请求时长限制的设置是有原因的，重构你的代码，将长时间执行的请求进行碎片化处理，一定要考虑，而不是一味的增加超时。
