从GrailsDomainClass grails获取mapWith静态域字段值

问题描述

我怎样才能得到一个域类的mapWith属性？

How can I get mapWith property of a domain class?

我试过domainClass.mapWith，因为它是域类的一个静态属性。
我也尝试了mappedBy，但它是一个不同的上下文。

I tried domainClass.mapWith as it's a static property of domain class.It didn't work.I also tried mappedBy but it's a different context.

任何关于如何从GrailsDomainClass获取mapWith值的想法

Any idea on how can i get mapWith value from GrailsDomainClass

以下是我的域名： -

Below is my domain:-

public class Ticket {
    String id

    List<Long> productInstanceId

    static hasMany = [productInstanceId:Long]

    static mapWith = "none"

}

推荐答案

如果您正在直接检查特定域，那么您可以使用域类获取静态属性。在你的情况下，它会是 Ticket.mapWith 或 Ticket.class.mapWith 。

If you are doing a direct check on a particular domain then you can fetch the static property with domain class. In your case it would be Ticket.mapWith or Ticket.class.mapWith.

如果您正在进行动态检查，那么您可以借助 DefaultGrailsDomainClass 来找到它。

If you are doing a dynamic check then you can find it with the help of DefaultGrailsDomainClass.

GrailsDomainClass aClass = new DefaultGrailsDomainClass(clazz)
aClass.mappingStrategy
