Using `CustomAutowireConfigurer`

CustomAutowireConfigurer 是 BeanFactoryPostProcessor，它允许您注册您自己的自定义限定符注解类型，即使它们未使用 Spring 的 @Qualifier 注解进行注解。以下示例显示如何使用 CustomAutowireConfigurer：

CustomAutowireConfigurer is a BeanFactoryPostProcessor that lets you register your own custom qualifier annotation types, even if they are not annotated with Spring’s @Qualifier annotation. The following example shows how to use CustomAutowireConfigurer:

<bean id="customAutowireConfigurer"
		class="org.springframework.beans.factory.annotation.CustomAutowireConfigurer">
	<property name="customQualifierTypes">
		<set>
			<value>example.CustomQualifier</value>
		</set>
	</property>
</bean>

AutowireCandidateResolver 通过以下方式确定自动装配候选对象：

The AutowireCandidateResolver determines autowire candidates by:

The autowire-candidate value of each bean definition
Any default-autowire-candidates patterns available on the <beans/> element
The presence of @Qualifier annotations and any custom annotations registered with the CustomAutowireConfigurer

当多个 Bean 满足自动装配候选对象的条件时，确定“主要”候选对象的方式如下：如果候选对象中恰好有一个 Bean 定义将 primary 属性设置为 true，则选择该 Bean 定义。

When multiple beans qualify as autowire candidates, the determination of a “primary” is as follows: If exactly one bean definition among the candidates has a primary attribute set to true, it is selected.
