如何在job 执行类中获得spring 的applicationContext

架构：spring+struts2+ibatis+quartz
现象：想在job执行类中注入业务bean，结果没有成功。那只能获得applicationConxtext，然后getBean.
解决：

	private static final String APPLICATION_CONTEXT_KEY = "applicationContext";

	public final ApplicationContext getApplicationContext(
			JobExecutionContext context) throws JobExecutionException {
		ApplicationContext applicationContext = null;
		try {
			applicationContext = (ApplicationContext) context.getScheduler()
					.getContext().get(APPLICATION_CONTEXT_KEY);
		} catch (SchedulerException e) {
			throw new JobExecutionException(e);
		}
		return applicationContext;
	}

Spring 与Quartz之间的配置，重点是最后一句注入：

	<bean id="scheduler" name="springQuartz" lazy-init="false"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="quartzProperties">
			<props>
				<prop key="org.quartz.scheduler.instanceName">
					SpringScheduler
				</prop>
				<prop key="org.quartz.scheduler.instanceId">AUTO</prop>
				<prop key="org.quartz.jobStore.class">
					org.quartz.impl.jdbcjobstore.JobStoreTX
				</prop>
				<prop key="org.quartz.jobStore.driverDelegateClass">
					org.quartz.impl.jdbcjobstore.StdJDBCDelegate
				</prop>
				<prop key="org.quartz.jobStore.tablePrefix">
					meta_task_
				</prop>
			</props>
		</property>
		<property name="applicationContextSchedulerContextKey">
			<value>applicationContext</value>
		</property>

得到ApplicationContext为空，不知有没有什么地方需要注意的？

我上次说的不够全面，请再看一下。

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.SchedulerException;
import org.springframework.context.ApplicationContext;

public class BaseTask {

	private static final String APPLICATION_CONTEXT_KEY = "applicationContext";

	public final ApplicationContext getApplicationContext(
			JobExecutionContext context) throws JobExecutionException {
		ApplicationContext applicationContext = null;
		try {
			applicationContext = (ApplicationContext) context.getScheduler()
					.getContext().get(APPLICATION_CONTEXT_KEY);
		} catch (SchedulerException e) {
			throw new JobExecutionException(e);
		}
		return applicationContext;
	}
}

public class MultiSinglePointMonitor extends BaseTask implements Job{

	private void setServiceBean(JobExecutionContext context) throws Exception {
		ApplicationContext applicationContext = getApplicationContext(context);
		metaQtySinglePointResultService = (MetaQtySinglePointResultService) applicationContext
				.getBean("metaQtySinglePointResultService");
		singlePointMonitorService = (SinglePointMonitorService) applicationContext
				.getBean("singlePointMonitorService");
	}
}
