javax.net.ssl.SSLException : SSLSocketFactory is null 异常

Question

我对以下代码有疑问...

System.setProperty("javax.net.ssl.keyStoreType", "pkcs12");
System.setProperty("javax.net.ssl.trustStoreType", "jks");
System.setProperty("javax.net.ssl.keyStore","C:\\ClientKeyStore\\ClientKeyStore.p12");
System.setProperty("javax.net.ssl.trustStore","C:\\ClientKeyStore\\ClientKeyStore.keystore");
System.setProperty("javax.net.debug", "ssl");
System.setProperty("javax.net.ssl.keyStorePassword", "keystorepass");
System.setProperty("javax.net.ssl.trustStorePassword", "truststorepass");

SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
URL url = new URL("https://url.com");
HttpsURLConnection httpCon = (HttpsURLConnection) url.openConnection();
httpCon.setSSLSocketFactory(sslsocketfactory);
OutputStream out=httpCon.getOutputStream();

我尝试使用 System.setProperty(key,value) 方法设置信任库、 keystore 和 SSL 上下文的其他属性，但出现以下错误。

javax.net.ssl.SSLException: SSLSocketFactory is null. This can occur if javax.net.ssl.SSLSocketFactory.getDefault() is called to create a socket and javax.net.ssl.* properties are not set.

有人可以帮我解决这个问题吗

您甚至可以在 Windows 上尝试使用正斜杠作为路径:

System.setProperty("javax.net.ssl.keyStoreType", "pkcs12");
System.setProperty("javax.net.ssl.trustStoreType", "jks");
System.setProperty("javax.net.ssl.keyStore","C:/ClientKeyStore/ClientKeyStore.p12");
System.setProperty("javax.net.ssl.trustStore","C:/ClientKeyStore/ClientKeyStore.keystore");
System.setProperty("javax.net.debug", "ssl");
System.setProperty("javax.net.ssl.keyStorePassword", "keystorepass");
System.setProperty("javax.net.ssl.trustStorePassword", "truststorepass");


SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();

这是你所有的代码吗？您的属性看起来不错，我能够使用您的示例创建套接字工厂。
