PropertyPlaceholderConfigurer 在磁盘上找不到属性文件

我正在尝试将工作的 spring WAR 转移到 OSGI 环境（在 glassfish 3.1 和蓝图中，spring 3.0.5）。应用程序从磁盘加载属性文件，如下所示：

<bean id="myProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="${my_conf}/my.properties"/>
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
</bean>

我在调试器中看到 ${my_conf}/my.properties 已转换为现有路径 (c:\conf\my.properties)

我使用在下一个 bean 声明中的 my.properties 中定义的属性 jms.url

<amq:broker useJmx="false" persistent="false" brokerName="embeddedbroker">
    <amq:transportConnectors>
        <amq:transportConnector uri="tcp://${jms.url}"/>
        <amq:transportConnector uri="vm://embeddedbroker" />
    </amq:transportConnectors>
</amq:broker>

在部署中，我收到异常 “无法解析占位符 ${jms.url}”

为什么呢失败？还有另一种方法可以从磁盘上的文件加载属性吗？

谢谢

I am trying to move a working spring WAR to OSGI environment (in glassfish 3.1 and blueprint, spring 3.0.5).
The application loads properties file from disk, like this:

<bean id="myProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="${my_conf}/my.properties"/>
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
</bean>

I see in debugger that ${my_conf}/my.properties is translated to the existing path (c:\conf\my.properties)

I use the property jms.url defined in my.properties in the next bean declaration

<amq:broker useJmx="false" persistent="false" brokerName="embeddedbroker">
    <amq:transportConnectors>
        <amq:transportConnector uri="tcp://${jms.url}"/>
        <amq:transportConnector uri="vm://embeddedbroker" />
    </amq:transportConnectors>
</amq:broker>

And in deployment I get an exception "Could not resolve placeholder ${jms.url}"

Why it fails? Is there another way to load properties from file on disk?

thank you
