序列号java

‘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。

试试是否可以:)

‘贰’ 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;
}
}
