quartz 的job中获取到applicationContext

第一步:
定义SchedulerFactoryBean的applicationContextSchedulerContextKey
<bean name="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
                <!-- 注入数据源 -->  
		<property name="dataSource">  
			<ref bean="dataSource" />  
		</property>
                <!-- 延迟30秒启动Scheduler -->  
		<property name="startupDelay" value="30"></property>
                <!-- 通过applicationContextSchedulerContextKey属性配置spring上下文 -->  
		<property name="applicationContextSchedulerContextKey">  
			<value>applicationContext</value>  
		</property> 
</bean>
 
定义之后,产生的效果是:
this.scheduler.getContext().put(this.applicationContextSchedulerContextKey, this.applicationContext);
第二步:
获取到scheduler,然后从中取出applicationContext 即可
public class TestJob extends QuartzJobBean {

	@Override
	protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
		Scheduler scheduler = (Scheduler) context.getScheduler();  
		//获取JobExecutionContext中的service对象  
               try {
                        //获取JobExecutionContext中的service对象 
			SchedulerContext schCtx = context.getScheduler().getContext();
                        //获取Spring中的上下文  
			ApplicationContext appCtx = (ApplicationContext)schCtx.get("applicationContext");
			jobService= (JobService)appCtx.getBean("jobService");
			....
		} catch (SchedulerException e1) {
			// TODO 尚未处理异常
			e1.printStackTrace();
		} 
	} 
};
