这篇文章很老，但是对我来说，解决Windows 8上描述的问题对我很有用。
JR Utily的解决方案无法完全发挥作用：如果拔下读取器然后再次插入，则CardTerminal实例上会出现错误。
因此，我添加了一些代码以清除端子列表，如下面的代码所示。
Class pcscterminal = Class.forName("sun.security.smartcardio.PCSCTerminals"); Field contextId = pcscterminal.getDeclaredField("contextId"); contextId.setAccessible(true); if(contextId.getLong(pcscterminal) != 0L) { // First get a new context value Class pcsc = Class.forName("sun.security.smartcardio.PCSC"); Method SCardEstablishContext = pcsc.getDeclaredMethod( "SCardEstablishContext", new Class[] {Integer.TYPE } ); SCardEstablishContext.setAccessible(true); Field SCARD_SCOPE_USER = pcsc.getDeclaredField("SCARD_SCOPE_USER"); SCARD_SCOPE_USER.setAccessible(true); long newId = ((Long)SCardEstablishContext.invoke(pcsc, new Object[] { SCARD_SCOPE_USER.getInt(pcsc) } )); contextId.setLong(pcscterminal, newId); // Then clear the terminals in cache TerminalFactory factory = TerminalFactory.getDefault(); CardTerminals terminals = factory.terminals(); Field fieldTerminals = pcscterminal.getDeclaredField("terminals"); fieldTerminals.setAccessible(true); Class classMap = Class.forName("java.util.Map"); Method clearMap = classMap.getDeclaredMethod("clear"); clearMap.invoke(fieldTerminals.get(terminals)); }
