java - 如何从 quartz 调度程序的属性文件中获取值？

Question

我在基于java的web应用程序中使用spring 2.0.6和quartz 1.5.2。想知道如何配置我的 applicationContext-quartz.xml 以便我可以从属性文件中读取值。即我想读取我的文件

<property name="imageFolder" value="${config.imageFolder}" />
<property name="rawImageFolder" value="${config.rawImageFolder}" />
<property name="imageOutputFolder" value="${config.imageOutputFolder}" />

而不是

<property name="imageFolder" value="/path/to/dir1" />
<property name="rawImageFolder" value="/path/to/dir2" />
<property name="imageOutputFolder" value="/path/to/dir3" />

使用the PropertyPlaceholderConfigurer mechanism :

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <!-- change this to your property location -->
        <value>classpath:quartz.properties</value>
    </property>
</bean>
