jsoup访问页面: PKIX path building failed

在用jsoup访问页面时报错
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
这是由于安全认证的问题，网上解决办法很多，
我们只需要在Jsoup.connect(webSite)之前添加方法忽略证书信任问题
trustAllHttpsCertificates();
HttpsURLConnection.setDefaultHostnameVerifier(hv);
java代码：
HostnameVerifier hv = new HostnameVerifier() {
        public boolean verify(String urlHostName, SSLSession session) {
            System.out.println("Warning: URL Host: " + urlHostName + " vs. "
                               + session.getPeerHost());
            return true;
        }
    };

private 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;
}
}
