Grails的FindBy *與inteface財產

我有一個像Grails的FindBy *與inteface財產

class Account { 

    BigDecimal balance = 0 
    SortedSet transactions 

    AccountOwner owner 

    static constraints = { 
    } 

    static hasMany = [transactions:Transaction] 
}

一個類時，我嘗試查詢帳戶像

def account = Account.findByOwner(user)

我得到這個錯誤

使用此接口

package br.com.fisgo.financial; 

public interface AccountOwner { 

}

我用嘲笑的對象，用於測試

感謝

您可以添加您的AccountOwner域名類嗎？ – Joseph 2012-04-27 19:58:15

包br.com.fisgo.financial; public interface AccountOwner { } 它在AccountOwner.java文件中 – 2012-04-27 20:20:14

由於findBy *由GORM和格姆處理不處理，我不認爲這是去上班的接口。你可以讓AccountOwner成爲抽象類嗎？
