estou usando quartzo com mola e quero injetar / usar outra classe na classe de trabalho e não sei como fazê-lo corretamente

o xml:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

   <!-- Scheduler task -->
   <bean name="schedulerTask" class="com.mkyong.quartz.SchedulerTask" />

   <!-- Scheduler job -->
   <bean name="schedulerJob"
       class="org.springframework.scheduling.quartz.JobDetailBean">

     <property name="jobClass" value="com.mkyong.quartz.SchedulerJob" />

     <property name="jobDataAsMap">
        <map>
          <entry key="schedulerTask" value-ref="schedulerTask" />
         </map>
      </property>
   </bean>

   <!-- Cron Trigger -->
   <bean id="cronTrigger"
    class="org.springframework.scheduling.quartz.CronTriggerBean">

    <property name="jobDetail" ref="schedulerJob" />
    <property name="cronExpression" value="0/10 * * * * ?" />

   </bean>

   <!-- Scheduler -->
   <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="jobDetails">
       <list>
          <ref bean="schedulerJob" />
       </list>
    </property>

    <property name="triggers">
        <list>
        <ref bean="cronTrigger" />
        </list>
    </property>
   </bean>

</beans>

o trabalho de quartzo:

package com.mkyong.quartz;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class SchedulerJob extends QuartzJobBean
{
    private SchedulerTask schedulerTask;

    public void setSchedulerTask(SchedulerTask schedulerTask) {
        this.schedulerTask = schedulerTask;
    }

    protected void exe,cuteInternal(JobExecutionContext context)
    throws JobExecutionException {

        schedulerTask.printSchedulerMessage();

    }
}

a tarefa a ser executada:

package com.mkyong.quartz;

public class SchedulerTask {

   public void printSchedulerMessage() {

       System.out.println("Struts 2 + Spring + Quartz ......");

   }
}

Eu quero injetar outra classe DTO que lida com o banco de dados na classe de tarefas para fazer algum trabalho de banco de dados na tarefa, como fazer isso?
