java中注释的嵌套_java-如何从注释处理器中的嵌套注释中读
取...
我试图使⽤Java注释处理⼯具⽣成⼀些代码，我具有嵌套的注释，其中⽗注释值是⼦注释的数组,⽽⼦注释值是类的数组.
注释：
public @interface ParentAnnotation {
ChildAnnotation[] value();
}
public @interface ChildAnnotation {
Class>[] value();
}
⽤法：
session如何设置和读取@ParentAnnotation(
{
@ChildAnnotation({Foo.class, Bar.class}),
@ChildAnnotation({Goo.class, Doo.class})
})
public class Sample{
}
在带有我的Processor⼦类型的注释上调⽤value()失败，发⽣以下异常：
