JDL: UndeclaredEntityException

Question

我正在用jdl对我的数据库进行原型化，我喜欢它的简单性。问题是文档有点轻，我得到了一个错误：UndeclaredEntityException: In the relationship between Room and Pictures, Pictures is not declared.

下面是代码：

...

entity Room {
    RoomId Integer required,
    RoomName String,
    SquareFootage Integer,
    HasRefrigirator Boolean,
    PrivateBathroom Boolean
}

entity Picture {
    Picture Integer required,
    Url String
}
...

relationship OneToMany {
    Room to Pictures{RoomId},
    ....
}

我不知道这意味着什么。

Answer 1

这就是问题所在。

relationship OneToMany {
    Room to Pictures{RoomId},
    ....
}

将Pictures更改为Picture
