建立SSL连接时pkix路径生成失败

显然,valicert class 3 CA证书不在默认的信任库中(可能是jre lib/security目录中的cacerts文件,但请参见 JSSE documentation 完整的故事)。

您可以将此证书添加到cacerts文件,但我不推荐这样做。相反,我认为您应该创建自己的信任库文件(可以是cacerts文件的副本),并将valicert根CA添加到此文件中。然后指向此文件 javax.net.ssl.trustStore 系统属性。

我想我应该用我实际做的事情来更新这个答案。使用Gregs提供的文档,我为valicert创建了一个信任管理器。在信任管理器中,我加载证书文件:

public class ValicertX509TrustManager implements X509TrustManager {

    X509TrustManager pkixTrustManager;

    ValicertX509TrustManager() throws Exception {

        String valicertFile = "/certificates/ValicertRSAPublicRootCAv1.cer";
        String commwebDRFile = "/certificates/DR_10570.migs.mastercard.com.au.crt";
        String commwebPRODFile = "/certificates/PROD_10549.migs.mastercard.com.au.new.crt";

        Certificate valicert = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(valicertFile));
        Certificate commwebDR = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(commwebDRFile));
        Certificate commwebPROD = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(commwebPRODFile));

        KeyStore keyStore = KeyStore.getInstance("JKS");
        keyStore.load(null, "".toCharArray());
        keyStore.setCertificateEntry("valicert", valicert);
        keyStore.setCertificateEntry("commwebDR", commwebDR);
        keyStore.setCertificateEntry("commwebPROD", commwebPROD);

        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
        trustManagerFactory.init(keyStore);

        TrustManager trustManagers[] = trustManagerFactory.getTrustManagers();

        for(TrustManager trustManager : trustManagers) {
            if(trustManager instanceof X509TrustManager) {
                pkixTrustManager = (X509TrustManager) trustManager;
                return;
            }
        }

        throw new Exception("Couldn't initialize");
    }

    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        pkixTrustManager.checkServerTrusted(chain, authType);
    }

    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        pkixTrustManager.checkServerTrusted(chain, authType);
    }

    public X509Certificate[] getAcceptedIssuers() {
        return pkixTrustManager.getAcceptedIssuers();
    }
}

现在,使用这个信任管理器,我必须创建一个套接字工厂:

public class ValicertSSLProtocolSocketFactory implements ProtocolSocketFactory {

    private SSLContext sslContext = null;

    public ValicertSSLProtocolSocketFactory() {
        super();
    }

    private static SSLContext createValicertSSLContext() {
        try {
            ValicertX509TrustManager valicertX509TrustManager = new ValicertX509TrustManager();
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, new ValicertX509TrustManager[] { valicertX509TrustManager}, null);
            return context;
        }

        catch(Exception e) {
            Log.error(Log.Context.Net, e);
            return null;
        }
    }

    private SSLContext getSSLContext() {
        if(this.sslContext == null) {
            this.sslContext = createValicertSSLContext();
        }

        return this.sslContext;
    }

    public Socket createSocket(String host, int port, InetAddress clientHost, int clientPort) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(host, port, clientHost, clientPort);
    }

    public Socket createSocket(final String host, final int port, final InetAddress localAddress, final int localPort, final HttpConnectionParams params) throws IOException {
        if(params == null) {
            throw new IllegalArgumentException("Parameters may not be null");
        }

        int timeout = params.getConnectionTimeout();
        SocketFactory socketFactory = getSSLContext().getSocketFactory();

        if(timeout == 0) {
            return socketFactory.createSocket(host, port, localAddress, localPort);
        }

        else {
            Socket socket = socketFactory.createSocket();
            SocketAddress localAddr = new InetSocketAddress(localAddress, localPort);
            SocketAddress remoteAddr = new InetSocketAddress(host, port);
            socket.bind(localAddr);
            socket.connect(remoteAddr, timeout);
            return socket;
        }
    }

    public Socket createSocket(String host, int port) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(host, port);
    }

    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    public boolean equals(Object obj) {
        return ((obj != null) && obj.getClass().equals(ValicertSSLProtocolSocketFactory.class));
    }

    public int hashCode() {
        return ValicertSSLProtocolSocketFactory.class.hashCode();
    }
}

现在我注册了一个新的协议:

Protocol.registerProtocol("vhttps", new Protocol("vhttps", new ValicertSSLProtocolSocketFactory(), 443));
PostMethod postMethod = new PostMethod(url);
for (Map.Entry<String, String> entry : params.entrySet()) {
    postMethod.addParameter(entry.getKey(), StringUtils.Nz(entry.getValue()));
}

HttpClient client = new HttpClient();
int status = client.executeMethod(postMethod);
if (status == 200) {
    StringBuilder resultBuffer = new StringBuilder();
    resultBuffer.append(postMethod.getResponseBodyAsString());
    return new HttpResponse(resultBuffer.toString(), "");
} else {
    throw new IOException("Invalid response code: " + status);
}

唯一的缺点是我必须创建一个特定的协议( vhttps )对于这个特殊的证书。
