How to pass values to spring schedular at run time?

[Gowher Naik]

I am using spring scheduling example as shown below.

  
<bean id="exampleBusinessObject" class="com.client.ExampleBusinessObject"/>
    
    <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="exampleBusinessObject" />
        <property name="targetMethod" value="doIt" />
        <property name="concurrent" value="false" />
    </bean>
  
    <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
        <property name="jobDetail" ref="jobDetail" />
        <!-- 1 seconds -->
        <property name="startDelay" value="1000" />
        <!-- repeat every 1 seconds -->
        <property name="repeatInterval" value="1000" />
    </bean>
        
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="simpleTrigger" />
            </list>
        </property>
    </bean>

public class ExampleBusinessObject {
   
    public void doIt() {
        System.out.println("[JOB]"+java.util.Calendar.getInstance().getTime());
    }
}

In above example the startDelay and repeatInterval is hardcoded in .xml file.
But my requirement is to pass these values at rune time.
Because these values are comming from web GUI used by Client.

Please help me.

Thanks

What kind of task you want to schedule in the scheduler? I guess it is possible to read the value from property file instead of hard coding into XML file. 'Start time' and 'Repeat time' is read at that time of server startup so later on even if you change any of those values you got to restart the server to see the effect.

Generally, Scheduler is used to create a daemon process which will run forever until you stop the server. For example, it can be used to send the emails to all the ranchers who have put watch on some topic.

Hope it helps you.
