First, the problem description:

When using spring to integrate quartz for dynamic tasks, when you want to use a service in a Job scheduled task, you can simply annotate @component, @Autowired cannot be injected, and get the object null. As in the following code:

Java code

1. @Component
2. @PersistJobDataAfterExecution
3. @DisallowConcurrentExecution
4. Public class Ticketsalepricelessthanlowestpricejob implements job{
6. @Autowired
7. private Xxxservice Xxxservice;
9. }

Second, the solution:

1, add a custom Class (Customjobfactory), inherit Springbeanjobfactory, the code is as follows:

Java code

2. Import Org.quartz.spi.TriggerFiredBundle;
4. Import org.springframework.beans.factory.annotation.Autowired;
6. Import Org.springframework.beans.factory.config.AutowireCapableBeanFactory;
8. Import Org.springframework.scheduling.quartz.SpringBeanJobFactory;
12. Public class Customjobfactory extends springbeanjobfactory{
16. @Autowired
18. private Autowirecapablebeanfactory capablebeanfactory;
22. @Override
24. protected Object createjobinstance (Triggerfiredbundle bundle) throws Exception {
26. //method of calling parent class
28. Object jobinstance = super.createjobinstance (bundle);
30. //To inject
32. Capablebeanfactory.autowirebean (jobinstance);
34. return jobinstance;
36. }
40. }

2, in the Spring.xml file configuration Customjobfactory, as follows:

Java code

1. <bean id="customjobfactory" class="Cn.imovie.manage.task.job.CustomJobFactory" ></bean>

3. Inject the custom customjobfactory into the Org.springframework.scheduling.quartz.SchedulerFactoryBean as follows:

Java code

1. <property name="jobfactory" ref="customjobfactory" ></property>

The complete code is as follows:

Java code

2. <!--timed task configuration start-to-
4. <bean id="Scheduler" class="Org.springframework.scheduling.quartz.SchedulerFactoryBean" >
6. <property name="DataSource" ref="DataSource" ></property>
8. <!--optional, Quartzscheduler update your existing job on startup, so you don't have to delete the Qrtz_job_details table record after each modification targetobject
10. <property name="overwriteexistingjobs" value="true"/>
12. <!--required, Quartzscheduler delay start, Quartzscheduler Restart after application start-up
14. <property name="Startupdelay" value="ten"/>
16. <!--settings Auto-start
18. <property name="Autostartup" value="true"/>
20. <property name="jobfactory" ref="customjobfactory" ></property>
22. <property name="Applicationcontextschedulercontextkey" value="Applicationcontextkey"/>
24. <property name="configlocation" value="classpath:spring-quartz.properties"/>
26. </bean>
28. <!--timed task configuration End--

4. You can then inject the service using @autowired in the Job task class.
