嗯，例外说明了一切。没有它可以访问的端口。
我看到了你发布的链接的代码。它尝试连接 COM2。那是设备所在的位置吗？如果它位于 COM1 上，请更改您的代码。
另一个原因是 JavaComm 安装。你把所有的东西都包括进去了吗？ DLL、JAR 等？如果是 DLL 问题，您也会收到 UnsatisfiedLinkError 异常，但无论如何。
Well the exception says it all. There is not such port it can access.
I saw the code of the link u posted. It tries to connect on COM2. Is that where the device is sitting? If it's sitting on COM1 change your code.
Another reason would be the JavaComm installation. Have you included everything? DLLs, JARs etc? If it was a DLL issue you would get the UnsatisfiedLinkError exception too but anyway.
