问题在Grails taglib中获取动态配置参数 [英] issue getting dynamic Config parameter in Grails taglib

问题描述

  String srcProperty =$ {attrs ['src' ]}。audio+（（attrs ['locale']）？_ $ {attrs ['locale']}：''）
 
 assert srcProperty ==prompt.welcomeMessageOverrideGreeting.audio 
  

其中我的配置有：

 提示{
 welcomeMessageOverrideGreeting {
 audio =/en/someFileName.wav
 txt =文本替代/en/someFileName.wav
 audio_es =/es/promptFileName.wav
 txt_es =Texto alternativo para /es/someFileName.wav
} 
} 
  
 
 
 
虽然这工作正常：
  String audio = $ {config.prompt.welcomeMessageOverrideGreeting.audio}
  
和：
 assert$ {config.prompt.welcomeMessageOverrideGreeting.audio}==/en/someFileName.wav
 
 
 
我无法得到这个工作：
  String audio = config.getProperty（prompt.welcomeMessageOverrideGreeting.audio）
  
 
 
解决方案
解决方案：这真的很难，但这里是我发现获得动态属性的原因：
  String audio = srcProperty.tokenize（'。'）.inject（config）{cfg，pr  - > cfg [pr]} 
  
我博客了一下：
  http：//www.baselogic .com / blog / development / grails-groovy-development / configslurper-with-dynamic-property-name-from-configurationholder-config-object   
I have a dynamic config parameter I want to get like:
    String srcProperty = "${attrs ['src']}.audio" + ((attrs['locale'])? "_${attrs['locale']}" : '')

    assert srcProperty == "prompt.welcomeMessageOverrideGreeting.audio"
where my config has:
prompt{
    welcomeMessageOverrideGreeting {
        audio = "/en/someFileName.wav"
        txt = "Text alternative for /en/someFileName.wav"
        audio_es = "/es/promptFileName.wav"
        txt_es = "Texto alternativo para /es/someFileName.wav"
    }
}
While this works fine:
String audio = "${config.prompt.welcomeMessageOverrideGreeting.audio}"
and:
        assert "${config.prompt.welcomeMessageOverrideGreeting.audio}" == "/en/someFileName.wav"

I can not get this to work:
String audio = config.getProperty("prompt.welcomeMessageOverrideGreeting.audio")

解决方案
SOLVED: This was REALLY tough, but here is what I found that worked to get a dynamic property:
String audio = srcProperty.tokenize( '.' ).inject( config ) { cfg, pr -> cfg[ pr ] }
I blogged about it:
