如何修复“java.security.cert.CertificateException:No subject alternative names present”错误？

Question

我有一个Java Web服务客户端，该客户端通过HTTPS使用Web服务。

import javax.xml.ws.Service;

@WebServiceClient(name = "ISomeService", targetNamespace = "http://tempuri.org/", wsdlLocation = "...")
public class ISomeService
    extends Service
{

    public ISomeService() {
        super(__getWsdlLocation(), ISOMESERVICE_QNAME);
    }

当我连接到服务URL（https://AAA.BBB.CCC.DDD:9443/ISomeService）时，出现异常java.security.cert.CertificateException: No subject alternative names present。

要解决此问题，我首先运行openssl s_client -showcerts -connect AAA.BBB.CCC.DDD:9443 > certs.txt并在file中获取以下内容certs.txt：

CONNECTED(00000003)
---
Certificate chain
 0 s:/CN=someSubdomain.someorganisation.com
   i:/CN=someSubdomain.someorganisation.com
-----BEGIN CERTIFICATE-----

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END CERTIFICATE-----

    Start Time: 1382521838
    Timeout   : 300 (sec)
    Verify return code: 21 (unable to verify the first certificate)
---

AFAIK，现在我需要

1. 提取的部分certs.txt之间-----BEGIN CERTIFICATE-----和-----END CERTIFICATE-----，
2. 对其进行修改，以使证书名称等于AAA.BBB.CCC.DDD和
3. 然后使用导入结果keytool -importcert -file fileWithModifiedCertificate（fileWithModifiedCertificate操作1和2的结果在哪里）。
   它是否正确？
   

如果是这样，我如何才能使第1步中的证书与基于IP的地址（AAA.BBB.CCC.DDD）一起使用？

Answer 1

我通过使用此处介绍的方法禁用HTTPS检查来解决此问题：

我将以下代码放入ISomeService该类中：

static {
    disableSslVerification();
}

private static void disableSslVerification() {
    try
    {
        // Create a trust manager that does not validate certificate chains
        TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }
        };

        // Install the all-trusting trust manager
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        // Create all-trusting host name verifier
        HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };

        // Install the all-trusting host verifier
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
}

由于我https://AAA.BBB.CCC.DDD:9443/ISomeService仅将它们用于测试目的，所以这是一个足够好的解决方案。
