服务器关闭使用httpclient和Java 7建立的连接

我正在尝试连接到使用SNI提供证书的远程服务器.我注意到服务器正在关闭使用Java 7编译和运行代码时建立的连接,而不是当我通过Java 8编译和运行代码时关闭.

下面是我为测试此假设而编写的代码.我切换Java版本并运行代码并获得不同的结果.

public static void getRequest() throws IOException, NoSuchAlgorithmException, KeyManagementException {
    String url = "https://sorry i can not share the exact url because of privacy concerns";

    HttpClient client = getClientInstance();
    HttpGet request = new HttpGet(url);

    HttpResponse response = client.execute(request);

    System.out.println("Response Code : "
            + response.getStatusLine().getStatusCode());

    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }
    System.out.println("####### the result is");
    System.out.println(result.toString());
}

private static org.apache.http.client.HttpClient getClientInstance() throws KeyManagementException, NoSuchAlgorithmException {
    RequestConfig defaultRequestConfig = RequestConfig.copy(RequestConfig.DEFAULT)
            .setConnectTimeout(60 * 1000)
            .setSocketTimeout(60 * 1000)
            .setConnectionRequestTimeout(60 * 1000)
            .build();

    return HttpClientBuilder.create().setDefaultRequestConfig(defaultRequestConfig).build();
}

有人遇到过这样的问题并已解决吗？我知道最终的解决方法是使用Java 8,但这不是我可以在当前时间限制内完成的任务,因为我调试的整个代码库非常庞大,并且依赖项可能不适用于Java 7.

抛出的异常如下所示；

以下也是我之前进行的SSL实验室测试的屏幕截图.

解决方法:

您没有在SSLLabs报告的一部分中列出支持的协议,但是我敢打赌,您会发现该服务器仅支持TLSv1.2或TLSv1.2和TLSv1.1,但不支持TLSv1.0.特别是,显然,由于对BEAST的反应过度(尽管它不值得在NVD中保留4.3),通常禁止处理受PCI DSS约束的支付交易的系统使用TLSv1.0(又名“早期TLS”).尽管在这种情况下,服务器应该发出警报70或71或40,而不仅仅是重置(或关闭).默认情况下,Java7(JSSE)客户端不执行TLSv1.2或TLSv1.1.

它可能取决于HttpClient的版本-我有4.5-但我认为您可以：

>为它创建一个适当配置的SSLConnectionSocketFactory和.setSSLSocketFactory,或者
> .useSystemProperties(true)并根据需要将sysprop https.protocols设置为TLSv1.2或TLSv1.1,TLSv1.2(也由javax.net.HttpsURLConnection使用),但这可能会影响您不需要的其他内容(请参见useSystemProperties的javadoc)
