如何使用新的scala 2.8.0嵌套注释

Question

看起来当scala 2.8.0出来时,我们可以在持久层中使用嵌套的@annotations.但是怎么样？任何人都可以请将这个从java转换为scala吗？谢谢.

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

Answer 1

您必须将元素包装在一起Array()并编写嵌套注释,如构造函数调用:

@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'")
))
