Java获取https网页内容报错SSLHandshakeException信任（忽略）所有SSL证书

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

原因：https出现信任弹出（访问网页时候弹出是否信任）

解决方案：忽略ssl证书

创建一个类忽略ssl证书

SslUtils.java

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;public class SslUtils {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;}}/*** 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);}
