首先如下:如何爲約束違反grails域對象設置自定義錯誤消息?所有的域定義的

package com.abc.def 

class EventDonation implements Serializable{ 

    String title 
    String body 
    BigDecimal customDonationMin 
    BigDecimal customDonationMax 


    static constraints = { 
     title blank: false, nullable: false 
     body blank: false, nullable: false 
     customDonationMin min: BigDecimal.ZERO 
    } 
} 

在視圖頁面的部分這使得誤差如下:

<g:hasErrors bean="${donation}">               
     <g:eachError var="error" bean="${donation}"> 
      <li><g:message error="${error}"/></li> 
     </g:eachError> 
    </g:hasErrors>  

最後在message.properties添加的行如下所示:

com.abc.def.eventDonation.customDonationMin.min = Minimum limit cannot be less than 0 

但是正被示出的錯誤是:

customDonationMin in class com.abc.def.EventDonation with value -10 is less than minimum value 0 

您知道自定義錯誤消息未顯示的原因嗎?
