如何使用新的Scala 2.8.0嵌套的注解 [英] how to use new scala 2.8.0 nested annotations

问题描述

看起来像斯卡拉时2.8.0已经出来了，我们可以用我们的持久层嵌套@annotations。但是如何？任何人都可以请从Java转换这Scala呢？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

您必须包装元素在阵列（），写嵌套注释就像一个构造函数调用

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'")
))
