在java中识别新设备 [英] Identify a new device in java

问题描述

我想知道连接新设备的时间。

I want to know when a new device is connected.

我了解到可以使用以下方式获取C＃中的所有当前设备：

I learned that it is possible to get all the current devices in C# using:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select VolumeName, DeviceID from Win32_LogicalDisk Where Not (VolumeName is null)");

然后 searcher.get（）返回这些设备的集合。

and then searcher.get() returns a collection of the devices.

我可以在java中使用与ManagementObjectSearcher并行的东西吗？
如果没有，是否有另一种获取连接设备列表的方法？或者找出新设备何时连接的其他方法？

Is there something parallel to ManagementObjectSearcher that i can use in java? If not, is there another way to get the list of connected devices? or another way to find out when a new device is being connected?

谢谢。

推荐答案

我知道在Java中没有真正的跨平台方式。如果您对仅支持Windows的解决方案感到满意，最简单的解决方案是生成一个C＃/ VBScript可执行文件，您可以使用 Runtime.exec（）从Java程序调用该文件。

I know of no real cross platform way to do this in Java. If you're happy with a Windows only solution, the simplest solution would be to generate a C# / VBScript executable you can call from your Java program with Runtime.exec().

如果你想要一个更好的解决方案需要更多工作（但仍然只有Windows）你可以使用 iKVM ，用于连接C＃和Java程序。

If you want a "nicer" solution that takes a bit more work (but still only Windows) you could use iKVM to interface between your C# and Java programs.

我唯一能想到的就是从跨平台的角度来看（这仍然使用本机库是使用RXTX轮询COM端口上的枚举，并检查什么时候发生了变化。这不会让你得到所有设备的列表，它只会工作对于使用COM端口的设备，但根据您的需要，它可能就足够了。这种方法的优点是RXTX二进制文件可以自由存在于每个公共平台。

The only thing I can think of from a cross platform perspective (and this still uses native libraries is to use RXTX to poll an enumerate on the COM ports, and check when something changes. This won't get you a list of all the devices, and it will only work for devices that use a COM port, but depending on your needs it may be enough. The plus side with this approach is that RXTX binaries freely exist for every common platform out there.
