JavaFX WebView无法加载某些网站

原因是

java.lang.Throwable: SSL handshake failed

一种解决方案可以是：从这篇文章http://codingdict.com/questions/107658：

     TrustManager trm = new X509TrustManager() {        public X509Certificate[] getAcceptedIssuers() {return null;}        public void checkClientTrusted(X509Certificate[] certs, String authType) {}        public void checkServerTrusted(X509Certificate[] certs, String authType) {}    };    SSLContext sc = SSLContext.getInstance("SSL");    sc.init(null, new TrustManager[] { trm }, null);    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

也有帖子，大概是类似的情况：JavaFx Webview JDK8无法加载自签名证书

我怎么知道那是

SSL handshake failed

webView.getEngine().getLoadWorker().stateProperty().addListener( new ChangeListener<Worker.State>() {     public void changed(Observablevalue ov, Worker.State oldState, Worker.State newState) { System.out.println(webView.getEngine().getLoadWorker().exceptionProperty());  ...

还添加添加

-Djavax.net.debug=all

URL-Loader-1，处理异常：javax.net.ssl.SSLHandshakeException：

sun.security.validator.ValidatorException：PKIX路径构建失败：

sun.security.provider.certpath.SunCertPathBuilderException：

无法找到到请求目标的有效认证路径
