java - 使用多个读卡器加载 PKCS 密钥库时出错

Question

在多终端设置中，从第 N 个（第一个除外）终端读取 CAC 卡时，我遇到了一个奇怪的问题。

环境 - JDK8_u211，无读卡器的Destop，笔记本电脑的内置读卡器，USB读卡器，CAC\PIV卡

用例尝试

当 CAC 卡插入笔记本电脑的内部插槽时，无论是否连接到笔记本电脑的 USB 卡终端，一切正常。
当 CAC 卡插入 USB 读卡器并连接到桌面时，一切正常。
当 CAC 卡插入 USB 读卡器并连接到笔记本电脑时，PKCS 存储实例化失败，因为配置使用 slot=1
当 CAC 卡插入 USB 读卡器并连接到笔记本电脑时，如果我在配置中硬编码 slot=4，一切正常。

问题：无法确定要在配置文件中使用的正确插槽。不知何故，终端的数量没有加起来以确定运行时的插槽。

通过启用 JDK 调试日志，我可以验证内部“C_GetSlotList”返回 0,4，因为我只有 2 个终端，因此使用索引 0 或 1。

有谁知道如何确定终端与插槽之间的相关性，或者我试图读卡的方式真的有问题吗？

请指教。

您对slot id和slot index感到困惑。它们是两个不同的属性。

为您提供C_GetSlotList了一组slot id's非插槽索引。在您的情况下0，并且4是插槽 ID，而不是插槽索引。插槽索引是数组中插槽 id 的索引。

在您getSmartCardTerminal()识别的方法中，您正在terminalIdx识别索引，但在您的registerProvider(Integer idx)方法中，您将索引映射为id，这里：

OPENSC_PKCS11_DLL + "\n插槽= " + idx + " "

当您使用您应该使用的插槽索引slotListIndex时，当您使用插槽 id 时，您应该使用slot.

因此，要解决您的问题，请将其更改为：

OPENSC_PKCS11_DLL + "\n slotListIndex = " + idx + " "
