Question

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，当我使用Java 7编译和运行代码时，服务器正在关闭连接，而不是在我通过Java 8编译和运行它时。

以下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修好了吗？我知道最终的解决方案是使用Java 8，但这不是我在当前时间限制内可以完成的任务，因为我调试的整个代码库非常庞大并且具有可能与Java 7不兼容的依赖关系。

抛出的异常如下;

您没有显示SSLLabs报告中列出支持的协议的部分，但我敢打赌您会发现此服务器仅支持TLSv1.2或TLSv1.2和TLSv1.1，但不支持TLSv1.0。特别是，处理受PCI DSS支付的支付交易的系统通常被禁止使用TLSv1.0（又名＆＃39;早期TLS＆＃39;）显然是由于对BEAST的过度反应（尽管它没有＆＃39; t值得）。虽然在这种情况下服务器应该提供警报70或71或40而不仅仅是重置（或关闭）。 Java7（JSSE）客户端默认不执行TLSv1.2或TLSv1.1。

它可能取决于HttpClient的版本 - 我有4.5 - 但我认为你可以：

为其创建经过适当配置的SSLConnectionSocketFactory和.setSSLSocketFactory，或
.useSystemProperties(true)并设置https.protocols或TLSv1.2 TLSv1.1,TLSv1.2（也由javax.net.HttpsURLConnection使用）的sysprop useSystemProperties，但这可能会影响其他内容你不想要（见{{1}}的javadoc）

服务器关闭使用httpclient和Java 7
