Spring WebServiceTemplate 导致频繁间歇性 java.net.SocketException: Connection reset

如何解决Spring WebServiceTemplate 导致频繁间歇性 java.net.SocketException: Connection reset

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。
