今天將jdk從1.6升級(jí)到1.7,但是HttpUrlConnection連接https出現(xiàn)問題了。

javax.net.ssl.SSLPRotocolException: handshake alert:  unrecognized_name    at sun.security.ssl.ClientHandshaker.handshakeAlert(ClientHandshaker.java:1288)    at sun.security.ssl.SSLSocketImpl.recvAlert(SSLSocketImpl.java:1904)    at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1027)    at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1262)    at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1289)    at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1273)    at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:523)    at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185)    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1296)    at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)    at java.net.URL.openStream(URL.java:1035)

問谷大哥,原來(lái)是jdk版本的問題，解決方法在代碼前加上

System.setProperty("jsse.enableSNIExtension", "false");
