我已将我的项目代码压缩到下面的示例中以显示我的问题。
示例/代码段引用了使用here和here的概念。 控制台输出显示发送的4个事件;所以我希望记事本中的输出是＆＃34; 12＆＃34;，但我只看到＆＃34; 1＆＃34;在记事本中。有人能指出我正确的方向吗？该jar是在Windows 10 x64上构建和运行的。

记事本仅显示“1”而非“12”，因为您发送的扫描代码错误。在这里，您首先发送 ESC KEY （ 0x01 ）的扫描码，然后发送 1 KEY的扫描码 （ 0x02 ）。
您应首先发送 1 KEY （ 0x02 ）的扫描码，然后 2 KEY （ 0x03 ）
使用ScanCode.java，这样您就不必记住扫描码。
