Question

我们在spring上下文中有这个现有的属性加载器配置

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <util:list>
            <value>hedging-service.properties</value>
        </util:list>
    </property>
</bean>

<!--Hedging properties bean that can be injected into other beans-->
<util:properties id="hedgingProperties" location="classpath:hedging-service.properties"/>

并且有一个bean引用了hedgingProperties bean

<bean id="mailProcessor"
    class="a.b.c.MailProcessor">
    <property name="properties" ref="hedgingProperties"/>
    ...
</bean>

我正在重构上下文以从多个属性文件加载，并避免重复定义属性。我的第一次尝试是使用这个bean代替上面的两个

<context:property-placeholder location="classpath:hedging-service-core.properties,classpath:hedging-service.properties,classpath:icon.properties"/>

但是当我使用hedgingProperties时，如何保留context:property-placeholder bean的别名或引用？

答案是混合context:property-placeholder和util:properties

<util:properties id="hedgingProperties" location="classpath:hedging-service.properties"/>
<context:property-placeholder properties-ref="hedgingProperties" />

<bean id="mailProcessor" class="a.b.c.MailProcessor">
    <property name="properties" ref="hedgingProperties"/>
    ...
</bean>

context：property-placeholder如何引用属性bean
