在Grails中是否有像onLoad（）这样的域类？

问题描述

伙计，

我有一个以下的域类：

  class Product {
 String name，
 String productRecord，
 
 static transients = ['productRecord'] 
} 
  
 
 
 
 productRecord是根据Product实例的id自动生成的字段。
 
 
 
所以我一直在想，是否有一个地方会在域实例加载时产生productRecord数字时自动调用？
 
 
 
最好的方法是做什么？
解决方案
您可以利用：
查看一些例子的文档。
 
Guys,

I have a following domain class:
class Product {
    String name,
    String productRecord,

    static transients = ['productRecord']
}
productRecord is a field which is generated automatically based on the id of the Product instance.
So I've been thinking, is there a place which will be automatically called when a domain instance is load to generate the productRecord number?
What's the best way to do that?
 解决方案 
You can probably leverage the built-in Domain Events:
Have a look at the docs for some examples.
