如何在Java中检查Windows版本？

Question

我想用Java检查Windows版本（基本或家庭或专业或业务或其他）。

我该怎么做？

Answer 1

你总是可以使用Java来调用Windows命令'systeminfo'，然后解析出结果，我似乎无法找到一种方法在Java中本地执行此操作。

JRE一个将返回Windows 8用于窗户8机：

import java.io.*; 

    public class GetWindowsEditionTest 
    { 
     public static void main(String[] args) 
     { 
     Runtime rt; 
     Process pr; 
     BufferedReader in; 
     String line = ""; 
     String sysInfo = ""; 
     String edition = ""; 
     String fullOSName = ""; 
     final String SEARCH_TERM = "OS Name:"; 
     final String[] EDITIONS = { "Basic", "Home", 
            "Professional", "Enterprise" }; 

     try 
     { 
      rt = Runtime.getRuntime(); 
      pr = rt.exec("SYSTEMINFO"); 
      in = new BufferedReader(new InputStreamReader(pr.getInputStream())); 

      //add all the lines into a variable 
      while((line=in.readLine()) != null) 
      { 
       if(line.contains(SEARCH_TERM)) //found the OS you are using 
       { 
       //extract the full os name 
        fullOSName = line.substring(line.lastIndexOf(SEARCH_TERM) 
        + SEARCH_TERM.length(), line.length()-1); 
        break; 
       } 
      } 

      //extract the edition of windows you are using 
      for(String s : EDITIONS) 
      { 
       if(fullOSName.trim().contains(s)) 
       { 
        edition = s; 
       } 
      } 

      System.out.println("The edition of Windows you are using is " 
           + edition); 

     } 
      catch(IOException ioe)  
      { 
       System.err.println(ioe.getMessage()); 
      } 
     } 
    }

你可以得到很多关于你在问的JVM它运行的系统信息的系统属性：

import java.util.*; 
public class SysProperties { 
    public static void main(String[] a) { 
     Properties sysProps = System.getProperties(); 
     sysProps.list(System.out); 
    } 
}

编辑：属性os.name似乎是您最好的选择

Answer 3

可以使用Apache Commons Library

SystemUtils类提供了几种确定此类信息的方法。

Answer 4

从System.getProperty("os.name")结果不同的Java虚拟机（连Sun/Oracle的那些）之间变化。对于同一个系统，在运行与JDK相同的程序时返回Windows NT (unknown)。

System.getProperty("os.version")对此似乎更可靠。对于Windows 7，它返回6.1和6.2对于Windows 8。

重构Hunter McMillen的answer更有效率和可扩展性。

import java.io.*; 

public class WindowsUtils { 
    private static final String[] EDITIONS = { 
     "Basic", "Home", "Professional", "Enterprise" 
    }; 

    public static void main(String[] args) { 
     System.out.printf("The edition of Windows you are using is: %s%n", getEdition()); 
    } 

    public static String findSysInfo(String term) { 
     try { 
      Runtime rt = Runtime.getRuntime(); 
      Process pr = rt.exec("CMD /C SYSTEMINFO | FINDSTR /B /C:\"" + term + "\""); 
      BufferedReader in = new BufferedReader(new InputStreamReader(pr.getInputStream())); 
      return in.readLine(); 
     } catch (IOException e) { 
      System.err.println(e.getMessage()); 
     } 
     return ""; 
    } 

    public static String getEdition() { 
     String osName = findSysInfo("OS Name:"); 
     if (!osName.isEmpty()) { 
      for (String edition : EDITIONS) { 
       if (osName.contains(edition)) { 
        return edition; 
       } 
      } 
     } 
     return null; 
    } 
} 

Answer 6

public static void main(String[] args) { 
    System.out.println("os.name: " + System.getProperty("os.name")); 
    System.out.println("os.version: " + System.getProperty("os.version")); 
    System.out.println("os.arch: " + System.getProperty("os.arch")); 
} 

输出：

os.name: Windows 8.1 
os.version: 6.3 
os.arch: amd64
