Class CombinationAnnotationElement

java.lang.Object

cn.hutool.core.annotation.CombinationAnnotationElement

All Implemented Interfaces:

Serializable, AnnotatedElement

public class CombinationAnnotationElement
extends Object
implements AnnotatedElement, Serializable

组合注解 对JDK的原生注解机制做一个增强，支持类似Spring的组合注解。
核心实现使用了递归获取指定元素上的注解以及注解的注解，以实现复合注解的获取。

Since:

4.0.9
