JAVA HttpsURLConnection - Exception NoSuchAlgorithmException

Question

我在Java 1.8.0_201中使用HttpsURLConnection连接到url的代码

String u = "https://test.com/prova.asmx?WSDL";
URL url = new URL(u);
System.out.println("Link: " + u);

HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
//con.setSSLSocketFactory(sc.getSocketFactory());
System.out.println("After url connection");
BufferedReader br = new BufferedReader(new     InputStreamReader(con.getInputStream()));
String input;
while ((input = br.readLine()) != null) {
System.out.println(input);
}
br.close();

我用以下命令从命令行启动程序

java -Djavax.net.ssl.trustStore=ws_cacerts_prod -Djavax.net.ssl.trustStorePassword=changeit -Djavax.net.ssl.keyStore=ws_cacerts_prod -Djavax.net.ssl.keyStorePassword=changeit -Djavax.net.debug=ssl -Djdk.tls.client.protocols=TLSv1 -Dhttps.protocols=TLSv1 TestHTTPS

我得到了这个异常

我尝试将keystore中的所有密码证书更改为与keystore相同，但结果相同。我怎样才能解决这个问题?

这个错误是因为;您的连接没有路由为HTTPS连接。你能不能这样试试:

SSLContext sc = SSLContext.getInstance("TLSv1.2");
sc.init(null, null, new java.security.SecureRandom());
HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
con.setSSLSocketFactory(sc.getSocketFactory());
