问题描述
我们在应用程序日志中看到频繁的间歇性java.net.socketException：连接重置错误。我一直在阅读类似的其他问题，但找不到相关的解决方案来修复或在本地环境中重现错误的方法。有人可以指导吗？
客户端的 HTTPClient 代码（以下所有超时设置为 60000）
@postconstruct
public void init() {
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setcontextpaths(CONTEXT_PATH);
setMarshaller(marshaller);
setUnmarshaller(marshaller);
PoolingHttpClientConnectionManager poolingConnManager = new PoolingHttpClientConnectionManager();
poolingConnManager.setDefaultMaxPerRoute(10);
RequestConfig config = RequestConfig.custom().setConnectTimeout(CONNECT_TIMEOUT)
.setConnectionRequestTimeout(REQUEST_TIMEOUT)
.setSocketTimeout(SOCKET_TIMEOUT).build();
CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(poolingConnManager)
.addInterceptorFirst(new HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
.setDefaultRequestConfig(config)
.build();
HttpComponentsMessageSender httpComponentsMessageSender = new HttpComponentsMessageSender(httpClient);
getwebservicetemplate().setMessageSender(httpComponentsMessageSender);
getwebservicetemplate().setDefaultUri("serverURL");
}

我无法使用wireshark（如某些地方所建议的那样），因为它需要在生产机器上获得很多权限。我们在这里遗漏了一些明显的东西。这个错误以前从未出现过，最近才开始。申请中没有相关的变化可以怀疑。 为了在本地重现，我尝试将 Thread.sleep 放在服务器应用程序中超过 1 分钟，但这并没有重现连接重置错误。我们正在使用 spring 3、httpclient 4.5.9 并在 tomcat 8 上部署客户端应用程序。
