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

<!-- 由spring生成scheduler --><bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><!--<property name="jobFactory"><bean class="cn.zto.job.JobBeanJobFactory"/></property>--><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

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

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

[java] view plain copy

print?

package cn.zto.job;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;
public class JobBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {
private ApplicationContext applicationContext;
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
@Override
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
Object jobInstance = super.createJobInstance(bundle);
//把Job交给Spring来管理，这样Job就能使用由Spring产生的Bean了
applicationContext.getAutowireCapableBeanFactory().autowireBean(jobInstance);
return jobInstance;
}
}

package cn.zto.job;import org.quartz.spi.TriggerFiredBundle;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.scheduling.quartz.SpringBeanJobFactory;public class JobBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {    private ApplicationContext applicationContext;    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {        this.applicationContext = applicationContext;    }    @Override    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {        Object jobInstance = super.createJobInstance(bundle);        //把Job交给Spring来管理，这样Job就能使用由Spring产生的Bean了        applicationContext.getAutowireCapableBeanFactory().autowireBean(jobInstance);        return jobInstance;    }}

xml配置

[html] view plain copy

print?

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