java怎么读取硬件信息?

把这个方法放到你的类下边

public void testGetSysInfo() {

//这个是信息变量

String address = "";

//获得系统名称

String os = System.getProperty("os.name");

if (os != null && os.startsWith("Windows")) {

//抓异常

try {

//定义dos命令

String command = "cmd.exe /c ipconfig /all";

//执行dos命令

Process p = Runtime.getRuntime().exec(command);

BufferedReader br = new BufferedReader(new InputStreamReader(p

.getInputStream()));

String line;

while ((line = br.readLine()) != null) {

if (line.indexOf("Physical Address") > 0) {

int index = line.indexOf(":");

index += 2;

address = line.substring(index);

break;

}

}

br.close();

logger.info("mac address:" + address.trim());

} catch (IOException e) {

logger.info("Error:" + e);

}

}

}
