quartz 中service不能注入？

Question

@Controller
public class SystemJob extends QuartzJobBean {

	private TaoBaoService taoBaoService;

	@Override
	protected void executeInternal(final JobExecutionContext context)
			throws JobExecutionException {
		System.out.println(taoBaoService);
		taoBaoService.test();
	}

	@Autowired
	public void setTaoBaoService(final TaoBaoService taoBaoService) {
		this.taoBaoService = taoBaoService;
	}

	@RequestMapping("test")
	public void test() {
		System.out.println(taoBaoService);
		System.out.println("test..");
	}
}

<!-- quartz -->
<bean id="systemJob" class="org.springframework.scheduling.quartz.JobDetailBean">
	<property name="jobClass" value="com.pqc.tbk.web.scheduling.SystemJob"></property>
</bean>
<bean id="myCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
	<property name="jobDetail">
		<ref bean="systemJob"/>
	</property>
	<property name="cronExpression" value="0 10 0 * * ? *"/>
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
	<property name="triggers">
		<list>
			<ref bean="myCronTrigger"/>
		</list>
		</property>
	</bean>

直接通过地址栏访问test打印的不是null

但是通过任务执行，打印的是null，奇怪的是既然service是null，执行test()方法竟然没有报空指针？应该是注入成功了啊？

Answer 2

难道说任务是系统启动时设定的，而在启动的时候service还没有注入进去？
