最近一段时间写一个授权的程序,需要获取很多信息来保证程序不能随意复制使用,必须经过授权才可以。
为了限制用户使用的操作系统,必须有统一的方法来获取才可以。
在JAVA中,通过System.getProperty("os.name")来获取,通过参考:http://lopica.sourceforge.net/os.html
针对windows系统,这里不具体判断是那个版本,如果有需要,可以在判断出windows之后,继续判断,判断需要考虑java的版本,版本不同,结果也不一样。
下面上代码:
1.枚举类型:EPlatform
/**
* 平台
* @author isea533
*/
public enum EPlatform {
Any("any"),
Linux("Linux"),
Mac_OS("Mac OS"),
Mac_OS_X("Mac OS X"),
Windows("Windows"),
OS2("OS/2"),
Solaris("Solaris"),
SunOS("SunOS"),
MPEiX("MPE/iX"),
HP_UX("HP-UX"),
AIX("AIX"),
OS390("OS/390"),
FreeBSD("FreeBSD"),
Irix("Irix"),
Digital_Unix("Digital Unix"),
NetWare_411("NetWare"),
OSF1("OSF1"),
OpenVMS("OpenVMS"),
Others("Others");
private EPlatform(String desc){
this.description = desc;
}
public String toString(){
return description;
}
private String description;
}
2.操作系统类:OSinfo
/**
* 操作系统类:
* 获取System.getProperty("os.name")对应的操作系统
* @author isea533
*/
public class OSinfo {
private static String OS = System.getProperty("os.name").toLowerCase();
private static OSinfo _instance = new OSinfo();
private EPlatform platform;

public static boolean isOpenVMS(){

}
/**

*/
public static EPlatform getOSname(){
if(isAix()){
_instance.platform = EPlatform.AIX;

_instance.platform = EPlatform.Digital_Unix;

/**

我使用的Windows 7 识别出来:Windows ,如果大家使用别的操作系统,希望能把操作系统和结果在这里留言写下来。
如果结果错误,你可以使用下面的代码获取你的操作系统信息:
class WhatOS
{
public static void main( String args[] )
{
System.out.println( System.getProperty("os.name") );
System.out.println( System.getProperty("os.version") );
System.out.println( System.getProperty("os.arch") );
}
}
