通过groovy / grails检测平台（Window或Linux） [英] Detecting the platform (Window or Linux) by groovy/grails

问题描述

pre $ System.properties ['os.name']


将返回操作系统的名称，例如Windows XP。因此，如果你想知道你是否在Windows上运行，你可以这样做：

  if .properties ['os.name']。toLowerCase（）。contains（'windows'））{
 println它是Windows
} else {
 println它不是Windows
 
 $ / code> 

或者， org.apache.commons.lang.SystemUtils （来自 Apache commons-lang 项目）暴露了一些布尔常量，它们提供了与上述代码相同的信息，例如



  SystemUtils.IS_OS_MAC 
 SystemUtils.IS_OS_WINDOWS 
 SystemUtils.IS_OS_UNIX 
  

这些更具体的常量也可用

  SystemUtils.IS_OS_WINDOWS_2000 
 SystemUtils.IS_OS_SOLARIS 
 SystemUtils.IS_OS_MAC_OSX 
  




Is there a way to detect the platform (Window / Linux) in which the website is running by Groovy / Grails?

解决方案

System.properties['os.name']

will return the name of the OS, e.g. "Windows XP". So if you want to figure out whether you're running on Windows or not, you could do something like:

if (System.properties['os.name'].toLowerCase().contains('windows')) {
    println "it's Windows"
} else {
    println "it's not Windows"
}

Alternatively, org.apache.commons.lang.SystemUtils (from the Apache commons-lang project) exposes some boolean constants that provide the same information as the code above, e.g.

SystemUtils.IS_OS_MAC
SystemUtils.IS_OS_WINDOWS
SystemUtils.IS_OS_UNIX

More specific constants such as these are also available

SystemUtils.IS_OS_WINDOWS_2000
SystemUtils.IS_OS_SOLARIS
SystemUtils.IS_OS_MAC_OSX
