(v) Two problems with spring + Quartz complex business: Getting the spring context and the auto-injection service class

The configuration is as follows:

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:task= "Http://www.springframework.org/schema/task"Xmlns:context= "Http://www.springframework.org/schema/context"xsi:schemalocation= "Http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsd Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd/HTTP Www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd " >    <Context:component-scanBase-package= "Cn.zno" />    <Task:executorID= "Threadpooltaskexecutor"pool-size= "1" />        <Beanclass= "Org.springframework.scheduling.quartz.SchedulerFactoryBean">        < Propertyname= "Jobfactory">            <Beanclass= "Org.springframework.scheduling.quartz.SpringBeanJobFactory" />        </ Property>        < Propertyname= "Applicationcontextschedulercontextkey"value= "Applicationcontextkey" />        < Propertyname= "Startupdelay"value= "0" />        < Propertyname= "Overwriteexistingjobs"value= "true" />        < Propertyname= "Exposeschedulerinrepository"value= "true" />        < Propertyname= "Taskexecutor"ref= "Threadpooltaskexecutor" />        < Propertyname= "Triggers">            <List>                <refBean= "Crontrigger_1" />            </List>        </ Property>    </Bean>    <BeanID= "Crontrigger_1"class= "Org.springframework.scheduling.quartz.CronTriggerFactoryBean">        < Propertyname= "Jobdetail"ref= "Jobdetail_1" />        < Propertyname= "Cronexpression"value="* * * * * ?" />    </Bean>    <BeanID= "Jobdetail_1"class= "Org.springframework.scheduling.quartz.JobDetailFactoryBean">        < Propertyname= "Jobclass"value= "Cn.zno.job.Breathe" />    </Bean>    <BeanID= "Breath"class= "Cn.zno.job.Breathe" /></Beans>

Why do you want to configure this

<name= "Applicationcontextschedulercontextkey"  value= " Applicationcontextkey "/>

Because this key can be used to fetch the spring context.

Problem with configuration 1: cannot be injected automatically.

 PackageCn.zno.job;ImportOrg.quartz.Job;ImportOrg.quartz.JobExecutionContext;Importorg.quartz.JobExecutionException;ImportOrg.springframework.context.ApplicationContext;ImportCn.zno.service.AService; Public classBreatheImplementsJob {//@Autowired//private Aservice Aservice;@Override Public voidExecute (jobexecutioncontext context)throwsjobexecutionexception {Try {//aservice.show ();ApplicationContext CTX = (applicationcontext) Context.getscheduler (). GetContext (). Get ("Applicationcontextkey"); Aservice Aservice= Ctx.getbean (aservice.class);        Aservice.show (); } Catch(Exception e) {e.printstacktrace (); }                    }}

Configure a change: Solve auto-injection problem

Change

        <name= "jobfactory">            <class = "Org.springframework.scheduling.quartz.SpringBeanJobFactory" />        </  Property >

To

        <name= "jobfactory">            <class = "Cn.zno.common.SpringBeanJobFactory" />        </  Property >

Cn.zno.common.SpringBeanJobFactory

 PackageCn.zno.common;ImportOrg.quartz.spi.TriggerFiredBundle;Importorg.springframework.beans.BeansException;ImportOrg.springframework.context.ApplicationContext;ImportOrg.springframework.context.ApplicationContextAware; Public classSpringbeanjobfactoryextendsorg.springframework.scheduling.quartz.SpringBeanJobFactoryImplementsApplicationcontextaware {PrivateApplicationContext ApplicationContext; @Override Public voidSetapplicationcontext (ApplicationContext applicationcontext)throwsbeansexception { This. ApplicationContext =ApplicationContext; } @OverrideprotectedObject createjobinstance (Triggerfiredbundle bundle)throwsException {Object jobinstance=Super. Createjobinstance (bundle);        Applicationcontext.getautowirecapablebeanfactory (). Autowirebean (jobinstance); returnjobinstance; }}

Another way to achieve this is:

 PackageCn.zno.common;ImportOrg.quartz.spi.TriggerFiredBundle;Importorg.springframework.beans.factory.annotation.Autowired;Importorg.springframework.beans.factory.config.AutowireCapableBeanFactory; Public classSpringbeanjobfactoryextendsorg.springframework.scheduling.quartz.SpringBeanJobFactory {@AutowiredPrivateautowirecapablebeanfactory autowirecapablebeanfactory; @OverrideprotectedObject createjobinstance (Triggerfiredbundle bundle)throwsException {Object jobinstance=Super. Createjobinstance (bundle);        Autowirecapablebeanfactory.autowirebean (jobinstance); returnjobinstance; }}
