<bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    		
    		<property name="schedulerName" value="scheduler"/>
    		<property name="configLocation" value="classpath:cn/zto/quartz/quartz.properties" />
    	</bean>

由于将Scheduler交给[spring][]生成， SchedulerFactoryBean有个jobFactory属性 而且jobFactory是实现SchedulerContextAware的类还要继承AdaptableJobFactory

![Center][]

jobFactorySet是个默认为false的boolean类型的

在Spirng-context-support  jar包下org.springframework.scheduling.quartz包中有个SpringBeanJobFactory的类继承了AdaptableJobFactory实现AdaptableJobFactory

spring会默认使用这个给jobFactory

我们可以继承SpringBeanJobFactory重写他的createJobInstance方法

![Center 1][]

当Spring在加载配置文件时，如果配置文件中有Bean实现了ApplicationContextAware接口时

Spring会自动调用setApplicationContext方法

我们可以通过这个获取Spring上下文然后在创建Job时让Job自动注入到Spring容器中

JobBeanJobFactory.class
