CertificateException: No subject alternative DNS name matching XXX found 解决办法

最近访问第三方接口传递数据，出现SSL证书认证失败的情况，于是做出了如下努力：
1.安装了对应网站的证书，提示证书安装成功，但是还是不可以访问；
2.查阅资料，得知JDK8以后添加了证书验证的配置，将对应配置进行修改，发现还是不可以访问；
决定在代码层跳出SSL验证
异常信息如下：

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching XXX found.

新增跳过证书的类，TrustAllTrustManager.java，代码如下：

public class TrustAllTrustManager implements javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager {

@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}

@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}

@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}

}

在HttpSendUtils.java文件中添加，如下代码：

// 直接通过主机认证
HostnameVerifier hv = new HostnameVerifier() {
@Override
public boolean verify(String urlHostName, SSLSession session) {
return true;
}
};
// 配置认证管理器
javax.net.ssl.TrustManager[] trustAllCerts = {new TrustAllTrustManager()};
SSLContext sc = SSLContext.getInstance("SSL");
SSLSessionContext sslsc = sc.getServerSessionContext();
sslsc.setSessionTimeout(0);
sc.init(null, trustAllCerts, null);
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// 激活主机认证
HttpsURLConnection.setDefaultHostnameVerifier(hv);
URL url = new URL(url);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
