java 获取 电脑 主板和硬盘序列号

When you need to know hardware details, Java is not the best tool unless you call a JNI routine or an external utility. The JNI solution is always the best because it is designed to interact closely with Java but it may be more complex to develop. If your need is simple (no interaction) and the need to be cross plateform is not present then calling an external utility is maybe "a good enough" choice.
如上所述，要想获取硬件信息，java不是最好的方式。。。
In these 2 examples, we create the appropriate VBS script file on-the-fly and capture its output. They are very Windows oriented since they rely on the "Windows Script Host" to execute the generated scripts.

The vbscript queries a WMI class to get a specific hardware information. Here we are using the Win32_BaseBoard but they are many others, see http://msdn2.microsoft.com/en-us/library/aa389273.aspx for complete list.

Hard disk serial number
//获取硬盘序列号
This serial number is created by the OS where formatting the drive and it's not the manufacturer serial number. It's unique, because it is created on the fly based on the current time information. AFAIK, there is no API that return that the manufacturer SN. At best, the SN of the HD firmware can be read but this will involve some very low-level API calls. Keep in mind that even if you get that number, there is no warranty that it will be unique since each manufacturer can assign the SN as they wish.
