jsoup訪問頁面: PKIX path building failed

在用jsoup訪問頁面時報錯
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

這是因爲安全認證的問題，網上解決辦法不少，
咱們只須要在Jsoup.connect(url)以前添加方法忽略證書信任問題

SSL.trustAllHttpsCertificates();
HttpsURLConnection.setDefaultHostnameVerifier(SSL.hv);

SSL類以下：

package main.java.SohuSpider.util;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;

public class SSL {
    static HostnameVerifier hv = new HostnameVerifier() {
        public boolean verify(String urlHostName, SSLSession session) {
            //System.out.println("Warning: URL Host: " + urlHostName + " vs. " + session.getPeerHost());
            return true;
        }
    };

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

    static class miTM implements javax.net.ssl.TrustManager, javax.net.ssl.X509TrustManager {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public boolean isServerTrusted(java.security.cert.X509Certificate[] certs) {
            return true;
        }

        public boolean isClientTrusted(java.security.cert.X509Certificate[] certs) {
            return true;
        }

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

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