Grails中是否有ElementCollection/CollectionOfElements的替代方案

Question

在Grails中是否有替代方案ElementCollection/CollectionOfElements？

我需要爲一組組件/可嵌入對象創建一個映射。

例如，一個人有一組地址，其中Address是一個可嵌入的對象。

@Embeddable 
class Address{ 
    ... 
} 

class Person{ 
    Set <Address> addresses 
} 

感謝

你需要的是組成。

class Person { 
    Address homeAddress 
    Address workAddress 
    static embedded = ['homeAddress', 'workAddress'] 
} 
class Address { 
    String number 
    String code 
}
