Using CustomAutowireConfigurer

{spring-framework-api}/beans/factory/annotation/CustomAutowireConfigurer.html[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>

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

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.
