JDK 目錄 jdk1.6.0_21\demo\management\MemoryMonitor 位置 jar demo源碼自參考
2. linux下java怎麼獲取CPU和硬碟序列號
JDK 目錄下 jdk1.6.0_21\demo\management\MemoryMonitor 位置下有個 jar 是demo。還有源碼，自己參考吧。
3. linux java怎麼獲取cpu
參考一下吧，代碼在附件裡面，java自帶的
4. java 能不能獲取CPU的ID號，硬碟的序列號
///==============================獲取CPU序列號========
package com.test;
import java.io.IOException;
import java.util.Scanner;
public class CpuUtil {
public static void main(String[] args) throws IOException {
long start = System.currentTimeMillis();
Process process = Runtime.getRuntime().exec(
new String[] { "wmic", "cpu", "get", "ProcessorId" });
process.getOutputStream().close();
Scanner sc = new Scanner(process.getInputStream());
String property = sc.next();
String serial = sc.next();
System.out.println(property + ": " + serial);
System.out.println("time:" + (System.currentTimeMillis() - start));
}
}
//=======================獲取硬碟序列號==========================
package com.test;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileWriter;
import java.io.InputStreamReader;
public class DiskUtil {
public static String getSerialNumber(String drive) {
String result = "";
try {
File file = File.createTempFile("realhowto",".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
+"Set colDrives = objFSO.Drives\n"
+"Set objDrive = colDrives.item(\"" + drive + "\")\n"
+"Wscript.Echo objDrive.SerialNumber"; // see note
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
}
catch(Exception e){
e.printStackTrace();
}
return result.trim();
}
public static void main(String[] args) {
String sn = DiskUtil.getSerialNumber("C");
System.out.println(sn);
}
//=============================獲取主板序列號====================
package com.test;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileWriter;
import java.io.InputStreamReader;
public class MiscUtil {
public static String getMotherboardSN() {
String result = "";
try {
File file = File.createTempFile("realhowto", ".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"
+ "Set colItems = objWMIService.ExecQuery _ \n"
+ " (\"Select * from Win32_BaseBoard\") \n"
+ "For Each objItem in colItems \n"
+ " Wscript.Echo objItem.SerialNumber \n"
+ " exit for ' do the first cpu only! \n" + "Next \n";
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec(
"cscript //NoLogo " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p
.getInputStream()));
String line;
while ((line = input.readLine()) != null) {
result += line;
}
input.close();
} catch (Exception e) {
e.printStackTrace();
}
return result.trim();
}
public static void main(String[] args) {
String cpuId = MiscUtil.getMotherboardSN();
System.out.println(cpuId);
}
}
5. linux怎麼查看cpu編號查詢
都在/proc/ 下面 cpu信息在/proc/cpuinfo 啟動時間在/proc/uptime 單位是s /proc/stat 裡面有cpu執行的時間，用戶態，系統態，空閑都有
