我有一个 Java Web 服务客户端，它通过 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，我收到异常 java.security.cert.CertificateException:没有主题替代名称存在。

要修复它，我首先运行 openssl s_client -showcerts -connect AAA.BBB.CCC.DDD:9443 > certs.txt 并在文件 certs.txt:

CONNECTED(00000003)

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

AFAIK，现在我需要

1. 提取 -----BEGIN CERTIFICATE----- 和 -----END CERTIFICATE-- 之间的 certs.txt 部分---,
2. 修改它，使证书名称等于AAA.BBB.CCC.DDD和
3. 然后使用 keytool -importcert -file fileWithModifiedCertificate 导入结果(其中 fileWithModifiedCertificate 是操作 1 和 2 的结果)。

这对吗？

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

更新 1(23.10.2013 15:37 MSK): 回复 similar question ，我阅读了以下内容:

If you're not in control of that server, use its host name (provided that there is at least a CN matching that host name in the existing cert).

“使用”到底是什么意思？

最佳答案

我通过使用 here 提供的方法禁用 HTTPS 检查来解决此问题:

我将以下代码放入 ISomeService 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();
    }
}

由于我使用 https://AAA.BBB.CCC.DDD:9443/ISomeService 仅用于测试目的，这是一个足够好的解决方案，但不要在生产中这样做。

请注意，您也可以为“一次一个连接”禁用 SSL，例如:

 // don't call disableSslVerification but use its internal code:
 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
 if (conn instanceof HttpsURLConnection) {
    HttpsURLConnection httpsConn = (HttpsURLConnection) conn;
    httpsConn.setHostnameVerifier(allHostsValid);
    httpsConn.setSSLSocketFactory(sc.getSocketFactory());
 }
