Java grails中每个类的InheritanceType.TABLE_的等价物？

我想为3个域类创建3个单独的表：A、B扩展A、C扩展B 但我希望他们的桌子不相互连接

---

在hibernate中，我会使用InheritanceType.TABLE\u PER\u类，在grails中，它的等价物是什么？

尝试使用tablePerHierarchy false

class Payment {
    Integer amount
    static mapping = {
        tablePerHierarchy false
    }
}

class CreditCardPayment extends Payment {
    String cardNumber
}

请参阅更多信息：

我也曾试图实现这一点，是的，grails也有可能实现这一点，这是一个稍微弯曲勺子以实现这一点的案例：

在Grails3下这样做

您有一个要扩展的基类，并且有具有相同字段的子表，即每个类的表：

我找到了另一篇有帮助的帖子，上面有一条评论，但现在要在这篇帖子上正确地展开和解释：

这本来是我们的基本域类，但它不是在

grails app/domains/

中创建的，而是在

src/main/groovy/test下创建的

package test

abstract class Tester {
    String name
    String something

    static mapping = {
        tablePerConcreteClass true
        id generator: 'increment'
        version false
    }
}

grails app/domains/test
中的下一个实际域类：

package  test
class Tester1 extends Tester {
}

及

看看mysql：

mysql> show create table tester2;

如果我使用它，子表将不会继承父表的字段。我需要他们被继承。作为他人的参考点
