Detecting Windows or Linux?
提问by Ron Whites
I am seeking to run a common Java program in both Windows and Linux.
我正在寻求在 Windows 和 Linux 中运行一个通用的 Java 程序。
The program needs to do some things differently on each platform.
该程序需要在每个平台上做一些不同的事情。
So how can / should my Java program detect it is running under Linux vs. Windows?
那么我的 Java 程序如何/应该如何检测它是在 Linux 还是 Windows 下运行？

You can use "system.properties.os", for example:
您可以使用“system.properties.os”，例如：
public class GetOs {
public static void main (String[] args) {
String s =
"name: " + System.getProperty ("os.name");
s += ", version: " + System.getProperty ("os.version");
s += ", arch: " + System.getProperty ("os.arch");
System.out.println ("OS=" + s);
}
}
// EXAMPLE OUTPUT: OS=name: Windows 7, version: 6.1, arch: amd64

有用的简单类由我分叉：https: //gist.github.com/kiuz/816e24aa787c2d102dd0
public class OSValidator {
private static String OS = System.getProperty("os.name").toLowerCase();
public static void main(String[] args) {
System.out.println(OS);
if (isWindows()) {
System.out.println("This is Windows");
} else if (isMac()) {
System.out.println("This is Mac");
} else if (isUnix()) {
System.out.println("This is Unix or Linux");
} else if (isSolaris()) {
System.out.println("This is Solaris");
} else {
System.out.println("Your OS is not support!!");
}
}
public static boolean isWindows() {
return OS.contains("win");
}
public static boolean isMac() {
return OS.contains("mac");
}
public static boolean isUnix() {
return (OS.contains("nix") || OS.contains("nux") || OS.contains("aix"));
}
public static boolean isSolaris() {
return OS.contains("sunos");
}
public static String getOS(){
if (isWindows()) {
return "win";
} else if (isMac()) {
return "osx";
} else if (isUnix()) {
return "uni";
} else if (isSolaris()) {
return "sol";
} else {
return "err";
}
}

I think It's a best approach to use Apache lang dependency to decide which OS you're running programmatically through Java
我认为这是使用 Apache lang 依赖项来决定您通过 Java 以编程方式运行的操作系统的最佳方法
import org.apache.commons.lang3.SystemUtils;
public class App {
public static void main( String[] args ) {
if(SystemUtils.IS_OS_WINDOWS_7)
System.out.println("It's a Windows 7 OS");
if(SystemUtils.IS_OS_WINDOWS_8)
System.out.println("It's a Windows 8 OS");
if(SystemUtils.IS_OS_LINUX)
System.out.println("It's a Linux OS");
if(SystemUtils.IS_OS_MAC)
System.out.println("It's a MAC OS");
}
}
