java序列号生成

‘壹’ 跪求在java里如何获得CPU的序列号，和硬盘的序列号。

利用Runtime call操作系统的命令，具体的命令取决于不同的操作系统，注意不要调用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])这个接口，不然复杂命令的执行会有问题。例子如下（拿cpu个数，其他类似）：
定义命令：
WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊
SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};
AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};
HPUXCmd = {"/bin/sh", "-c", "echo \"map\" | /usr/sbin/cstm | grep CPU | wc -l "};
linuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};

然后判断系统：
os = System.getProperty("os.name").toLowerCase();

根据不同的操作系统call不同的命令。

‘贰’ java如何获取本机主板序列号

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();
}
System.out.println(result);
return result.trim();
}

public static void main(String[] args)
{
getMotherboardSN();
}

这个是我在网上找的，但是只能在windows下获得主板序列号，在linux下就不行。我愁~在linux下如何获得主板序列号呢。

‘叁’ 用java实现字母与数字混合的唯一序号，且要递增

importjava.util.LinkedList;

publicclassReplaceNumber
{
	publicstaticvoidmain(String[]args)
	{
		LinkedList<String>result=newLinkedList<String>();
		charr='0',g='0',b='0';
		Stringrgb=""+r+g+b;
		while(!"ZZZ".equals(rgb))
		{
			if(b<':'||(b>='A'-1&&b<='Z'))
			{
				b++;
			}
			if(':'==b||'Z'+1==b)
			{
				if(g<':')
				{
					g++;
					b='9';
				}
				if(g<'Z'+1&&g>':')
				{
					g++;
					b='Z';
				}
			}
			if(':'==g||'Z'+1==g)
			{
				if(r<'9')
				{
					r++;
					g='9';
				}
				if(r<'Z'+1&&r>':')
				{
					r++;
					g='Z';
				}
			}
			rgb=""+r+g+b;
			if("999".equals(rgb))
			{
				r='A';
				g='0';
				b='0';
			}
			if("A99".equals(rgb))
			{
				r='A';
				g='A';
				b='0';
			}
			if("AA9".equals(rgb))
			{
				r='A';
				g='A';
				b='A'-1;
			}
			result.add(rgb);
		}
		System.out.println("唯一序列号：
"+result.toString().replaceAll("[\[\]]","").replaceAll("\,","
"));
	}
}

‘肆’ 求java自动生成一个序列号的方法，急急急...

package com.test4;

public class Test7 {
public static void main(String[] args) {
System.out.println(getNum("20100505",3));
}

//假设数据库里有个20100505005的编号
private static String getNum(String firstPart, int len) {
//调用数据库获得20100505005这个编号
String oldNum = "20100505005";
int num = Integer.parseInt(oldNum.replace(firstPart,""));
String numStr = ++num +"";
int length = numStr.length();
for (int i = length; i < len; i++) {
numStr = "0"+numStr;
}
return firstPart + numStr;
}
}

‘伍’ 如何用JAVA生成注册序列号

平常我们都接触过软件注册，输入序列号、激活码、注册码、授权码；对于这些字符码到底代表什么含义不甚了解，但一般来说，这些字符码中都有几个特点：
1、唯一性，肯定是一个唯一的序列号，否则就会存在滥用的问题。
2、加密性，肯定是经过加密或者混乱的，防止大家自己生成序列号。
3、解密性，软件自身肯定可以解密，否则无法验证合法性。
4、可读性，序列号一般都比较标准，方便书写和记忆，所以一般都为数字和字母。
以下给出简单示例：
[java] view plain
/**
* byte转哈希
* @param b
* @return
*/
public static String byte2hex(byte[] b) {
String hs = "";
String stmp = "";
for (int n = 0; n < b.length; n++) {
stmp = Integer.toHexString(b[n] & 0xFF);
if (stmp.length() == 1)
hs += ("0" + stmp);
else
hs += stmp;
}
return hs.toUpperCase();
}

/**
* 哈希转byte
* @param b
* @return
*/
public static byte[] hex2byte(byte[] b) {
if ((b.length % 2) != 0)
throw new IllegalArgumentException("长度不是偶数");

byte[] b2 = new byte[b.length / 2];

for (int n = 0; n < b.length; n += 2) {
String item = new String(b, n, 2);
b2[n / 2] = (byte) Integer.parseInt(item, 16);
}
return b2;
}

‘陆’ Java如何生成版本号比如0001 0002 0002

首先还是不太明白你说的这个“生成版本号”是什么意思，如果只是生成一个自增序列的话

1、如果有oracle数据库的话可以利用它的序列生成。

2、没有oracle，用redis也行。

3、没有数据库，那就写个文件来存取吧：

public class Test2 {

public static void main(String[] args) throws IOException {
System.out.println(getSequence("d:\test\sequence.txt"));
setSequence("d:\test\sequence.txt", "");
System.out.println(getSequence("d:\test\sequence.txt"));
}

//读取序列
public static String getSequence(String sequenceFile) throws IOException {
FileInputStream fileInputStream = null;
InputStreamReader inputStreamReader = null;
BufferedReader bufferedReader = null;
try {
File file = new File(sequenceFile);
fileInputStream = new FileInputStream(file);
inputStreamReader = new InputStreamReader(fileInputStream);
bufferedReader = new BufferedReader(inputStreamReader);
// 按行读取字符串
String str;
if ((str = bufferedReader.readLine()) != null) {
return str;
}
return null;
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
if (bufferedReader != null) {
bufferedReader.close();
}
if (inputStreamReader != null) {
inputStreamReader.close();
}
if (fileInputStream != null) {
fileInputStream.close();
}
}
}

//设置序列，如果传入的序列号为空，则在原序列的基础上+1
public static void setSequence(String sequenceFile, String sequence) throws IOException {
if (sequence == null || sequence.isEmpty()) {
String oriSequence = getSequence(sequenceFile);
Objects.requireNonNull(oriSequence);
sequence = String.format("%04d", Integer.valueOf(oriSequence) + 1);
}
FileOutputStream fileOutputStream = null;
OutputStreamWriter outputStreamWriter = null;
BufferedWriter bufferedWriter = null;
try {
File file = new File(sequenceFile);
fileOutputStream = new FileOutputStream(file);
outputStreamWriter = new OutputStreamWriter(fileOutputStream);
bufferedWriter = new BufferedWriter(outputStreamWriter);
bufferedWriter.write(sequence);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (bufferedWriter != null) {
bufferedWriter.close();
}
if (outputStreamWriter != null) {
outputStreamWriter.close();
}
if (fileOutputStream != null) {
fileOutputStream.close();
}
}
}
}

代码又挤在一起了：
