我正在编写代码以提取系统信息详细信息,即RAM,处理器速度并将其放在文本文件中。
public void getSpecs(){
//run a cmd command to convert msinfo32 to .txt file
String[] command = {
"cmd",
};
Process p;
try{
p= Runtime.getRuntime().exec(command);
new Thread(new Sec(p.getErrorStream(), System.err)).start();
new Thread(new Sec(p.getInputStream(), System.out)).start();
PrintWriter pw= new PrintWriter(p.getOutputStream());
pw.println("msinfo32 /report .\\specs.txt");
pw.close();
p.waitFor();
}catch(Exception e){
e.printStackTrace();
}
}
}
此过程需要很长时间,并且会转换整个文件。
最佳答案
msinfo32将计算机信息导出到文件中。由于它为每个计算机/ Windows组件检索了巨大的导出,因此预计会花费一些时间。
我已经使用Powershell做过类似的事情
public static void main(String[] args) throws IOException {
//Set the commands
String cmd = "powershell.exe get-WmiObject ";
String[] win32CmdA = {"win32_processor", "win32_computerSystem", "win32_logicaldisk"};
for (String win32Cmd : win32CmdA) {
String info = runCmd(cmd + win32Cmd,
"MaxClockSpeed",
"TotalPhysicalMemory",
"DeviceID",
"FreeSpace");//Add as many atributes you want to return from powershell output
System.out.println(info); // You can use a file writer here
}
// //You can handle ErrorStream here
// String line;
// BufferedReader stderr = new BufferedReader(new InputStreamReader(
// powerShellProcess.getErrorStream()));
// while ((line = stderr.readLine()) != null) {
// System.out.println(line);
// }
}
private static String runCmd(String cmd, String... attrs) throws IOException {
Process powerShellProcess = Runtime.getRuntime().exec(cmd);
powerShellProcess.getOutputStream().close();
String line;
String result="";
BufferedReader stdout = new BufferedReader(new InputStreamReader(powerShellProcess.getInputStream()));
while ((line = stdout.readLine()) != null) {
if (line != null && line.contains(":")) {
String nameValue[] = line.split(":");
if (Arrays.asList(attrs).contains(nameValue[0].trim())) {
result+=nameValue[0] + " - " + nameValue[1] + "\n";
}
}
}
stdout.close();
return result;
}
上面的代码在Powershell中为特定组件(处理器,computerSystem和逻辑磁盘)调用Windows Management Instrumentation(WMI)类。
然后,您定义应该从powershell输出中获取哪些值,例如MaxClockSpeed,TotalPhysicalMemory等。
如果更改System.out.println(info);使用文件编写器,您将在文件中包含此信息。
样本输出(大约需要3秒才能运行)
DeviceID - CPU0
MaxClockSpeed - 3401
TotalPhysicalMemory - 17053949952
DeviceID - C
FreeSpace - 56341774336
DeviceID - D
FreeSpace -
DeviceID - F
FreeSpace - 373687742464
