Обнаружение смарт-карт с помощью Java
Я использую следующий код, чтобы проверить, есть ли смарт-карта, подключенная к компьютеру или нет
public static boolean verifySmartCardPresence() {
boolean cardPresent = false;
try {
TerminalFactory tf = TerminalFactory.getDefault();
List<CardTerminal> terminals = tf.terminals().list();
for (CardTerminal terminal : terminals) {
if (terminal.isCardPresent()) {
System.out.println(terminal);
cardPresent = true;
}
}
return cardPresent;
} catch (CardException ex) {
LOGGER.error(ex.getMessage(), ex);
return false;
}
}
это работает как чудо, но когда я отключаю смарт-карту и подключаю ее снова, не закрывая программу, он больше не извлекает ее, это дает мне исключение, как будто нет подключенной смарт-карты, в чем проблема?
