豆名不斷的錯誤

最近我決定和Spring一起玩。我做了一些教程，一切似乎都很好，直到我嘗試使用多個屬性文件。正如互聯網所說，這足以做類似豆名不斷的錯誤

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="ignoreUnresolvablePlaceholders" value="true"/> 
     <property name="ignoreResourceNotFound" value="true"/> 
     <property name="location"> 
      <list> 
       <value>classpath:readData.properties</value> 
       <value>classpath:sendMail.properties</value> 
      </list> 
     </property> 
</bean>

呃，不幸的是它不起作用。令人驚訝的這個版本的作品（對於一個屬性的文件夾）：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="location"> 
       <value>classpath:readData.properties</value> 
     </property> 
</bean>

控制檯表示如下：

誰能幫助我？

編輯

@Denis Makarskiy 我已經嘗試過很多次，但沒有令人滿意的結果。現在我有

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionDecorator for element [property-placeholder] 
Offending resource: class path resource [Beans.xml]

您可以使用context：property-placeholder標記指定多個屬性文件。

例子：

<context:property-placeholder location="readData.properties, 
              sendMail.properties"/>

不要忘記架構添加上下文豆的標籤，就像這樣：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation=" http://www.springframework.org/schema/beans 
         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
         http://www.springframework.org/schema/context 
         http://www.springframework.org/schema/context/spring-context-3.1.xsd>
