問題得到動態配置參數Grails的標籤庫

Question

我有一個動態的配置參數，我想這樣的：

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

    assert srcProperty == "prompt.welcomeMessageOverrideGreeting.audio" 

在我的配置有：

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" 
    } 
} 

雖然這工作得很好：

String audio = "${config.prompt.welcomeMessageOverrideGreeting.audio}" 

and： assert「$ {config.prompt.welcomeMessageOverrideGreeting.audio}」==「/ en/so meFileName.wav」

我不能得到這個工作：

String audio = config.getProperty("prompt.welcomeMessageOverrideGreeting.audio")

解決：這是非常艱難的，但這裏是我發現工作取得動態特性：

String audio = srcProperty.tokenize('.').inject(config) { cfg, pr -> cfg[ pr ] } 

我的博客上講述它： http://www.baselogic.com/blog/development/grails-groovy-development/configslurper-with-dynamic-property-name-from-configurationholder-config-object

他們不是平放這樣，他們在分層存儲。 「config.prompt.welcomeMessageOverrideGreeting.audio」是從配置中獲得「提示」的簡寫，然後是「welcomeMessageOverrideGreeting」，然後是「audio」。如果你想用點符號只是扁平化配置：

String audio = config.flatten().getProperty("prompt.welcomeMessageOverrideGreeting.audio") 

Answer 3

在類路徑假設myconfig.groovy：

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" 
    } 
    } 

我們可以動態地構造自己的名字：

def myconfig = this.class.getResource("/myconfig.groovy") 
def config = new ConfigSlurper().parse(myconfig) 

def dynamic = "welcomeMessageOverrideGreeting" 
def dynamic2 = "audio" 
def locale = "es" 

assert config.prompt[dynamic].audio == "/en/someFileName.wav" 
assert config.prompt.welcomeMessageOverrideGreeting[dynamic2] == "/en/someFileName.wav" 
assert config.prompt.welcomeMessageOverrideGreeting["${dynamic2}_${locale}"] == "/es/promptFileName.wav" 
assert config.prompt[dynamic]["${dynamic2}_${locale}"] == "/es/promptFileName.wav"
