Class AliasLinkAnnotationPostProcessor

java.lang.Object

cn.hutool.core.annotation.AbstractLinkAnnotationPostProcessor

cn.hutool.core.annotation.AliasLinkAnnotationPostProcessor

All Implemented Interfaces:

SynthesizedAnnotationPostProcessor, Comparable<SynthesizedAnnotationPostProcessor>

public class AliasLinkAnnotationPostProcessor
extends AbstractLinkAnnotationPostProcessor

用于处理注解对象中带有Link注解，且Link.type()为 RelationType.ALIAS_FOR或RelationType.FORCE_ALIAS_FOR的属性。
当该处理器执行完毕后，Link注解指向的目标注解的属性将会被包装并替换为 AliasedAnnotationAttribute或ForceAliasedAnnotationAttribute。

Specified by:

processLinkedAttribute in class AbstractLinkAnnotationPostProcessor

Parameters:

synthesizer - 注解合成器

annotation - originalAttribute上的Link注解对象

originalAnnotation - 当前正在处理的SynthesizedAnnotation对象

originalAttribute - originalAnnotation上的待处理的属性

linkedAnnotation - Link指向的关联注解对象

linkedAttribute - Link指向的originalAnnotation中的关联属性，该参数可能为空
