Java 的“os.name"适用于 Windows 10?
在Java中,我们可以通过查看os.name
的属性值来知道底层操作系统的名称:System.getProperty("os.name")
.
In Java, we can see the property value of os.name
to know the name of the underlying operating system: System.getProperty("os.name")
.
对于每个版本的 Windows,它总是返回操作系统的确切名称:Windows XP
表示 XP,Windows Vista
表示 Vista,Windows 7
代表 7,Windows 8.1
代表 8.1,依此类推...
For each edition of Windows, it used to return always the exact name of the OS: Windows XP
for XP, Windows Vista
for Vista, Windows 7
for Seven, Windows 8.1
for 8.1, and so on...
问题是:我刚刚使用发布的 Microsoft 更新程序将我的 Windows 8.1 更新到了 Windows 10,而且这个属性似乎仍然存在 Windows 8.1
:
The problem is: I just updated my Windows 8.1 to Windows 10 using the released Microsoft updater, and it seems like this property still remains Windows 8.1
:
public class OSTest {
public static void main(String[] args) {
System.out.println(System.getProperty("os.name"));
}
}
如何为此创建解决方法?而且,有谁知道如果安装新的 Windows 10 副本,这个问题是否仍然存在 - 也就是说,这个错误是由 Microsoft 自动更新程序引起的 - ?
How can I create a workaround for this? And, does anyone know if this problem persists if installing a fresh Windows 10 copy - that is, this bug is caused by the Microsoft auto-updater -?
推荐答案
这是一个已知问题 JDK-8066504 已在即将发布的 Java 8 更新 60 中修复.
This is a known problem JDK-8066504 that has been fixed in upcoming Java 8 update 60.
原因是 GetVersionEx 函数的行为自Windows 8.1.

有多种可能的解决方法,请参阅 MSDN 文章.
