grails 3.1.10自定義驗證器問題沒有這個。定義

沒有什麼特別的情況，我相信它只是在最近纔開始發生試過grails clean尚未擺脫了問題：grails 3.1.10自定義驗證器問題沒有這個。定義

域類：

static constraints = { 
    someThing(nullable:true, validator: this.checkSomething) 
    } 
    static def checkSomething= { val, obj, errors -> 
     if (val && obj.something?.findAll()?.size()>2 { 
      errors.rejectValue("something.error", [''] as Object[], '') 
     } 
    }

沒有this.以下錯誤。有了this.staticMethod ide抱怨說這不是必需的。這是對的，我不應該需要它。只是想知道爲什麼奇怪的場景

錯誤引起的：

我發現包括明確指定用靜態方法的類名的解決方案。我猜這個問題來自於Grails用於支持靜態約束的Groovy攔截器魔術= {thingsThatLookLikeParamsButAreReallyMethodCalls}語法。

class MyClassFoo { 

    static constraints = { 
    someThing(nullable:true, validator: MyClassFoo.checkSomething) 
    } 

    static checkSomething= { val, obj, errors -> 
    // your logic 
    } 
}
