i am using quartz with spring and i want to inject/use another class in the job class and i don't know how to do it correctly

the 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>

the quartz job:

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(Sched

In your solution you are using the spring @Autowired annotation in a class that is not instantiated by Spring. Your solution will still work if you remove the @Autowired annotation because Quartz is setting the property, not Spring.

Quartz will try to set every key within the JobDataMap as a property. E.g. since you have a key "myDao" Quartz will look for a method called "setMyDao" and pass the key's value into that method.

If you want Spring to inject spring beans into your jobs, create a SpringBeanJobFactory and set this into your SchedulerFactoryBean with the jobFactory property within your spring context.

SpringBeanJobFactory javadoc:

Applies scheduler context, job data map and trigger data map entries as bean property values
