java - extended server_name (SNI Extension) 不是用jdk1.8.0发送而是用jdk1.7.0发送

Question

我已经使用 ApacheCXF (v3.0.4) 实现了一个 JAX-WS 客户端，并且一切正常，但是当我想对 java 8 (jdk1.8.0_25) 使用安全连接 (SSL/TLS) 时，问题就来了。

我在日志中看到以下异常 (-Djavax.net.debug=all):

main, handling exception: java.net.SocketException: Connection reset
main, SEND TLSv1.2 ALERT:  fatal, description =    unexpected_message
main, WRITE: TLSv1.2 Alert, length = 2
main, Exception sending alert: java.net.SocketException: Connection reset by peer: socket write error

经过深入分析后，我发现问题是由于 Java 8 未发送 server_name (SNI) 但 Java 7 已发送且 Web 服务调用成功。

Java 8 日志 (-Djavax.net.debug=all): 缺少“Extension server_name”

Java 7 日志 (-Djavax.net.debug=all)(有效):“Extension server_name”已设置

据观察，在 Java 7 中设置了扩展服务器名称，服务器名称:[主机名称:testeo.hostname.es]，然后网络服务调用成功。

为什么 Java 8 不像 Java 7 那样设置 server_name？是 Java 配置问题吗？

如前所述，原因与使用 setHostnameVerifier() 破坏 SNI(扩展服务器名称)的 JDK 错误有关。 https://bugs.openjdk.java.net/browse/JDK-8144566

我们的解决方法: 测试后，我们发现将连接的 SSLSocketFactory 设置为几乎任何默认值似乎都可以解决问题。

这不起作用: HttpsURLConnection.setSSLSocketFactory((SSLSocketFactory) SSLSocketFactory.getDefault());

这确实有效: HttpsURLConnection.setSSLSocketFactory(new SSLSocketFactoryFacade());

因此，要为 JAX-WS 客户端修复它，您可以这样做: bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", new SSLSocketFactoryFacade());

我们的 SSLSocketFactory facade:(注意它实际上什么都不做)

public class SSLSocketFactoryFacade extends SSLSocketFactory {

    SSLSocketFactory sslsf;

    public SSLSocketFactoryFacade() {
        sslsf = (SSLSocketFactory) SSLSocketFactory.getDefault();;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return sslsf.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return sslsf.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket socket, String s, int i, boolean b) throws IOException {
        return sslsf.createSocket(socket, s, i, b);
    }

    @Override
    public Socket createSocket(String s, int i) throws IOException, UnknownHostException {
        return sslsf.createSocket(s, i);
    }

    @Override
    public Socket createSocket(String s, int i, InetAddress inetAddress, int i1) throws IOException, UnknownHostException {
        return sslsf.createSocket(s, i, inetAddress, i1);
    }

    @Override
    public Socket createSocket(InetAddress inetAddress, int i) throws IOException {
        return createSocket(inetAddress, i);
    }

    @Override
    public Socket createSocket(InetAddress inetAddress, int i, InetAddress inetAddress1, int i1) throws IOException {
        return createSocket(inetAddress, i, inetAddress1, i1);
    }
}
