Question

我们正在使用Spring Reactive WebClient进行http调用。它在下面使用JettyClientHttpConnector。向外部服务器发出请求时，间歇性地开始引发EOF异常。

经过一些在线挖掘，发现该连接似乎已被服务器关闭。但是我找不到码头网络客户端使用的默认idleTimeout是什么。我希望在将固定值添加到生产代码并将其破坏之前，先了解idletimeout的值

return webclient.post()
        .uri(url)
        .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
        .header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE)
        .syncBody(request)
        .retrieve()
        .bodyToMono(responseType)

        });

No exception handler found for exception java.io.EOFException: HttpConnectionOverHTTP@78adba37::DecryptedEndPoint@39cf23c5{sfp-prod-1.infra.marcus.com/10.207.63.102:3128\u003c-\u003e/10.255.50.84:36250,OPEN,fill=-,flush=C,to=416480/0}

Answer 1

让我们看看异常顶部的三行。

首先，您有...

未找到异常java.io.EOFException的异常处理程序： HttpConnectionOverHTTP @ 78adba37 :: DecryptedEndPoint @ 39cf23c5 {sfp-prod-1.infra.marcus.com/10.207.63.102:3128\u003c-\u003e/10.255.50.84:36250,OPEN,fill =-，flush = C，to = 416480/0}

这告诉我们您有一个OPEN连接，没有过早关闭。

下一行...

org.eclipse.jetty.client.http.HttpReceiverOverHTTP.earlyEOF（HttpReceiverOverHTTP.java:338）[jetty-client-9.4.14.v20181114.jar：9.4.14.v20181114]

告诉我们您的EOF处于早期状态，通常表明您HTTP协议失败。

org.eclipse.jetty.http.HttpParser.parseNext（HttpParser.java:1551）〜[jetty-http-9.4.14.v20181114.jar：9.4.14.v20181114]

此行以代码形式告诉我们，您的客户端正在从另一端解析HTTP响应，该响应使用的是“块式” Transfer-Encoding，它解析了最后的关闭块0\r\n\r\n，但是读取缓冲区包含更多字节，这违反了HTTP规范。

WebClient通过EarlyEOF告诉您HTTP协议已到达EOF，但仍有未读取的数据。这种情况还意味着该连接上的HTTP协议无效，并且必须强制关闭该连接。

此状态，连接已关闭，关闭块丢失后的数据被报告为EOFException。

jetty webclient中的默认idleTimeout是什么？
