方面：財產佔位如何引用屬性豆

Question

我們在我們的Spring上下文這個現有的財產裝載機配置

<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"/> 

而且是引用hedgingProperties豆

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

我一個bean重構上下文以從多個屬性文件加載並避免重複定義屬性。我第一次嘗試是在地方兩個使用這個bean上述

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

，但我怎麼能留住別名或參考hedgingProperties豆當我使用context:property-placeholder？

Answer 1

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>
