如何使用新的 scala 2.8.0 嵌套注释 [英] how to use new scala 2.8.0 nested annotations

问题描述

看起来当 scala 2.8.0 出来时，我们可以在我们的持久层中使用嵌套的 @annotations.但是如何?任何人都可以将它从java转换为scala吗?谢谢.

looks like when scala 2.8.0 is out, we can use nested @annotations in our persistence layers. But how? Can anyone please transform this from java to scala? Thanks.

@NamedQueries({
    @NamedQuery(name = "findAll", query="select p from Person p"),
    @NamedQuery(name = "findTheOne",
          query="select p from Person p where p.name = 'Neo'")
})

推荐答案

您必须将元素包装在 Array() 中，并像构造函数调用一样编写嵌套注释:

You have to wrap the elements in an Array() and write the nested annotations like a constructor call:

@NamedQueries(Array(
    new NamedQuery(name = "findAll", query="select p from Person p"),
    new NamedQuery(name = "findTheOne",
          query="select p from Person p where p.name = 'Neo'")
))
