Question

I am following the following article.

http://www.mkyong.com/spring/spring-quartz-scheduler-example/

Everything works fine.

<bean id="simpleTrigger"

    class="org.springframework.scheduling.quartz.SimpleTriggerBean">

    <property name="jobDetail" ref="runMeJob" />
    <property name="repeatInterval" value="5000" />
    <property name="startDelay" value="1000" />

</bean>

I created a property file app.properties which has

 repeatInterval = 5000
 startDelay = 1000

I want to load these data into bean properties. Right now I have to hard code the values into the xml file.

I want to be able to load the data from property file into the bean properties. Is it possible?

EDIT:

I have

<property name="repeatInterval" value="5000" />

What I am looking for is a way to make it

<property name="repeatInterval" value= "get 5000 from property file" />

To find a file myPropertyFileName.properties that is on your classpath and load it into your spring config, create the following bean:

<bean id="myPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="location" value="classpath:myPropertyFileName.properties"/>
  <property name="placeholderPrefix" value="${props:"/>
</bean>

Then use a property name defined like

repeatInterval=5000 

like this:

<property name="repeatInterval" value="${props:repeatInterval}"/>
