SpringBoot忽略HTTPS请求的SSL证书

报错如下：

java.security.cert.CertificateException: No subject alternative names present

解决方案：

1、创建SslUtil工具类

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

/**
 * java信任SSL证书
 *
 */
public class SslUtil {

	/**
	 * 忽略HTTPS请求的SSL证书，必须在openConnection之前调用
	 * 
	 * @throws Exception
	 */
	public static void ignoreSsl() throws Exception {
		HostnameVerifier hv = new HostnameVerifier() {
			public boolean verify(String urlHostName, SSLSession session) {
				return true;
			}
		};
		trustAllHttpsCertificates();
		HttpsURLConnection.setDefaultHostnameVerifier(hv);
	}

	private static void trustAllHttpsCertificates() throws Exception {
		TrustManager[] trustAllCerts = new TrustManager[1];
		TrustManager tm = new miTM();
		trustAllCerts[0] = tm;
		SSLContext sc = SSLContext.getInstance("SSL");
		sc.init(null, trustAllCerts, null);
		HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
	}

	static class miTM implements TrustManager, X509TrustManager {
		public X509Certificate[] getAcceptedIssuers() {
			return null;
		}

		public boolean isServerTrusted(X509Certificate[] certs) {
			return true;
		}

		public boolean isClientTrusted(X509Certificate[] certs) {
			return true;
		}

		public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
			return;
		}

		public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
			return;
		}
	}

}

2、启动类添加方法，调用工具类中的方法

 @PostConstruct
 public void run() throws Exception{
     SslUtils.ignoreSsl();
 }
