java - 证书中的主机名不匹配？

Question

我尝试使用自签名证书连接到服务器。我使用此代码接受所有证书。

public class CertificateAcceptor {

    public void initializeTrustManager() {
        try {
            SSLContext context = SSLContext.getInstance("SSL");
            context.init(null, createTrustManager(), new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());

        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
    }

    private TrustManager[] createTrustManager() {

    TrustManager[] trustAllCerts = new TrustManager[] {
            new X509TrustManager() {

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }

                @Override
                public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // leave blank to trust all clients
                }

                @Override
                public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                    // leave blank to trust all servers
                    for (X509Certificate c : chain) {
                        System.out.println(c.toString());
                    }
                }

            }
        };
        return trustAllCerts;
    }

}

但是我得到了以下错误:

javax.net.ssl.SSLException: hostname in certificate didn't match: <xyz.ch> != <localhost>

    at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:641)
    at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:576)

我确定我的证书代码已执行，那么可能是什么问题？

ALLOW_ALL 不是正确答案。您应该使用带有 ext 扩展名的 keytool 以正确的名称设置您的证书:

keytool -genkeypair \
   -keystore keystore.jks \
  -dname "CN=OLEKSIYS-W3T, OU=Sun Java System Application Server, O=Sun Microsystems, L=Santa Clara, ST=California, C=US" \
  -keypass changeit \
  -storepass changeit \
  -keyalg RSA \
  -keysize 2048 \
  -alias default \
  -ext SAN=DNS:localhost,IP:127.0.0.1 \
  -validity 9999
