SSLServerSocket抛出EOFException

Question

我目前正在尝试在我的程序中实现SSL连接。但是当我现在尝试启动它时，会在堆栈跟踪之上抛出NoSuchAlgorithmException。

这里是完整的堆栈跟踪：

java.net.SocketException: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext)

所以，如果我们调查它，我们会看到这个EOFException - 这个含义很清楚。如果我打开密钥库文件，它是空的。但我不知道为什么。 以下是我尝试生成密钥库和证书的方法：

Scanner scr = new Scanner(System.in);
System.out.println("**** IMPORTANT ****");
System.out.println("You don't have a certificate for using SSL yet.");
System.out.println("We will create it together now!");
System.out.println();
System.out.print("Name of your organisation: ");
String ssl_o = scr.nextLine();
String ssl_ou = ssl_o;
System.out.print("Your name: ");
String ssl_cn = scr.nextLine();
System.out.print("Country code [de/en/fr]: ");
String ssl_c = scr.nextLine();
System.out.print("City: ");
String ssl_l = scr.nextLine();
System.out.print("State: ");
String ssl_st = scr.nextLine();
System.out.print("Password: ");
String pass = new String(scr.nextLine());

String execString = "keytool -genkey -keyalg RSA -alias dreamim -keystore " + KEYSTORE + " -storepass " + pass + " -validity 360 -dname \"cn=" + ssl_cn + ", o=" + ssl_o + ", ou=" + ssl_ou + ", c=" + ssl_c + ", l=" + ssl_l + ", st=" + ssl_st + "\" -keypass " + pass;
try
{
    Runtime.getRuntime().exec(execString);
}
catch (IOException e)
{
    // TODO Auto-generated catch block
    e.printStackTrace();
}

然后，在尝试创建SSLServerSocket时，我只是使用它：

SSLServerSocketFactory sslserversocketfactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
SSLServerSocket sslserversocket = (SSLServerSocket) sslserversocketfactory.createServerSocket(port);

我没有通过传递密钥库参数来执行JAR文件，但我在创建套接字之前使用了这段代码：

System.setProperty("javax.net.ssl.keyStore", KEYSTORE);
        System.setProperty("javax.net.ssl.keyStorePassword", keyStorePassword);

我不知道自己做错了什么。我真的很感激任何帮助。谢谢！
