javax.net.ssl.SSLException：SSLSocketFactory的是空

Question

我有下面的代碼有問題...

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(); 

我試圖設置信任存儲，密鑰存儲和使用System.setProperty(key,value) SSL上下文的其他屬性方法，但我收到以下錯誤。

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. 

有人可以幫我解決這個問題。

你可以嘗試着斜槓即使是在Windows的路徑：

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(); 

這是所有的代碼？你的屬性看起來很好，我可以用你的例子來創建一個套接字工廠。
