因为谷歌点“kotlin os名称”到这个页面，这里是@Memin的答案的kotlin版本:

private var _osType: OsTypes? = null
val osType: OsTypes
    get() {
        if (_osType == null) {
            _osType = with(System.getProperty("os.name").lowercase(Locale.getDefault())) {
                if (contains("win"))
                    OsTypes.WINDOWS
                else if (listOf("nix", "nux", "aix").any { contains(it) })
                    OsTypes.LINUX
                else if (contains("mac"))
                    OsTypes.MAC
                else if (contains("sunos"))
                    OsTypes.SOLARIS
                else
                    OsTypes.OTHER
            }
        }
        return _osType!!
    }

enum class OsTypes {
    WINDOWS, LINUX, MAC, SOLARIS, OTHER
}

你可以使用:

System.getProperty("os.name")

附注:你可能会发现这段代码很有用:

class ShowProperties {
    public static void main(String[] args) {
        System.getProperties().list(System.out);
    }
}

它所做的就是打印出Java实现提供的所有属性。它将使您了解通过属性可以了解Java环境的哪些信息。: -)

上面答案中的一些链接似乎被打破了。我在下面的代码中添加了指向当前源代码的指针，并提供了一种方法来处理以enum作为答案的检查，以便在计算结果时使用switch语句:

OsCheck.OSType ostype=OsCheck.getOperatingSystemType();
switch (ostype) {
    case Windows: break;
    case MacOS: break;
    case Linux: break;
    case Other: break;
}

helper类是:

/**
 * helper class to check the operating system this Java VM runs in
 *
 * please keep the notes below as a pseudo-license

 */
import java.util.Locale;
public static final class OsCheck {
  /**
   * types of Operating Systems
   */
  public enum OSType {
    Windows, MacOS, Linux, Other
  };

  // cached result of OS detection
  protected static OSType detectedOS;

  /**
   * detect the operating system from the os.name System property and cache
   * the result
   * 
   * @returns - the operating system detected
   */
  public static OSType getOperatingSystemType() {
    if (detectedOS == null) {
      String OS = System.getProperty("os.name", "generic").toLowerCase(Locale.ENGLISH);
      if ((OS.indexOf("mac") >= 0) || (OS.indexOf("darwin") >= 0)) {
        detectedOS = OSType.MacOS;
      } else if (OS.indexOf("win") >= 0) {
        detectedOS = OSType.Windows;
      } else if (OS.indexOf("nux") >= 0) {
        detectedOS = OSType.Linux;
      } else {
        detectedOS = OSType.Other;
      }
    }
    return detectedOS;
  }
}

String osName = System.getProperty("os.name");
System.out.println("Operating system " + osName);

我认为下面的内容可以用更少的字里行间覆盖更广的范围

import org.apache.commons.exec.OS;

if (OS.isFamilyWindows()){
                //load some property
            }
else if (OS.isFamilyUnix()){
                //load some other property
            }

试试这个，简单易行

System.getProperty("os.name");
System.getProperty("os.version");
System.getProperty("os.arch");
