https單向認證的服務端證書不是權威機構頒發的，網上找了點代碼不對https證書進行認證后，報如下異常
javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure at sun.security.ssl.Alerts.getSSLException(Alerts.java:192) at sun.security.ssl.Alerts.getSSLException(Alerts.java:154) at sun.security.ssl.SSLSocketImpl.recvAlert(SSLSocketImpl.java:2011) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1113) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1363) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1391) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1375) at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:563) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1512) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1440) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
網上查了查說是JCE認證導致，JDK1.9版本及以上無問題，更新成JDK1.9后ok
