如何从Config.groovy中派生相对目录的物理路径？ [英] How do I derive physical path of a relative directory inside Config.groovy?

问题描述

我正在尝试使用GitHub的源代码设置Weceem。它需要上传目录的物理路径定义，并且目录似乎用于编写可搜索的索引。上传的默认设置为：

  weceem.upload.dir ='file：/var/www/weceem.org/uploads /'
  

我想要定义那些使用相对路径的文件，例如WEB-INF / resources / uploads。我尝试了一种以前用于访问相对路径目录的方法：

 文件uploadDirectory = ApplicationHolder.application.parentContext。 getResource（WEB-INF / resources / uploads）。文件
 def absoluteUploadDirectory = uploadDirectory.absolutePath 
 weceem.upload.dir ='file：'+ absoluteUploadDirectory 
  

然而，ApplicationHolder.application下的'parentContext'是NULL。任何人都可以提供一个解决方案，这将允许我使用相对路径？

解决方案

看看你应该有的Config.groovy （可能是评论）

  //搜索配置文件的位置被合并到主配置中
 / / config文件可以是Java属性文件或ConfigSlurper脚本
 
 //classpath：$ {appName} -config.properties，classpath：$ {appName} -config.groovy，
 grails.config.locations = [
file：$ {userHome} /。grails / $ {appName} -config.properties，
file：$ {userHome} /。grails / $ {appName} -config.groovy

  

在部署服务器中创建Conig文件

 $ {userHome} /。grails / $ {appName} -config.properties
  

并在该配置文件中定义您的道具（即使不是相对路径）。

I am trying to set up Weceem using the source from GitHub. It requires a physical path definition for the uploads directory, and for a directory for appears to be used for writing searchable indexes. The default setting for uploads is:

weceem.upload.dir = 'file:/var/www/weceem.org/uploads/'

I would like to define those using relative paths like WEB-INF/resources/uploads. I tried a methodology I have used previously for accessing directories with relative path like this:

  File uploadDirectory = ApplicationHolder.application.parentContext.getResource("WEB-INF/resources/uploads").file
  def absoluteUploadDirectory = uploadDirectory.absolutePath
  weceem.upload.dir = 'file:'+absoluteUploadDirectory

However, 'parentContext' under ApplicationHolder.application is NULL. Can anyone offer a solution to this that would allow me to use relative paths?

解决方案

look at your Config.groovy you should have (maybe it is commented)

// locations to search for config files that get merged into the main config
// config files can either be Java properties files or ConfigSlurper scripts

// "classpath:${appName}-config.properties", "classpath:${appName}-config.groovy",
grails.config.locations = [
        "file:${userHome}/.grails/${appName}-config.properties",
        "file:${userHome}/.grails/${appName}-config.groovy"
]

Create Conig file in deployment server

"${userHome}/.grails/${appName}-config.properties"

And define your prop (even not relative path) in that config file.
