Programmatically set property of bean - spring

Question

I am trying to figure out how I can adjust the "period" property of the "destroyWorldTask" bean that is defined like this in my list of beans. Is this possible? What is the proper way to do this?
<bean id="mytimerfactory"
class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="daemon" value="true"/>
<property name="myTimerTasks">
<list>
<bean class="org.springframework.scheduling.timer.ScheduledTimerTask" id="destroyWorldTask">
<property name="delay" value="100"/>
<property name="period" value="10000/>
<property name="runnable">
<bean class="com.scene7.is.util.SafeRunnable">
<constructor-arg ref="destroyWorld"/>
</bean>
</property>
</bean>
</list>
</property>
</bean>

Answer 1

There are two possible answers:
1. If you want the "period" property be set somewhere in the program, you don't need to set in the context configuration. (Which I think not suitable for you, as you are using a spring class, not yours).
2. Extend from org.springframework.scheduling.timer.ScheduledTimerTask and make your edition of the class, something like:
public MyTimeScheduledTimerTast extends ScheduledTimerTask{
//...
}
and set that property in your program. (Now it's in your hand)
Then update your context configuration like this:
<bean id="mytimerfactory" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="daemon" value="true"/>
<property name="myTimerTasks">
<list>
<bean class="myPackage.MyScheduledTimerTask" id="destroyWorldTask">
<!-- Set those properties that are not set in your program -->
</bean>
</list>
</property>
</bean>
