设置org.springframework.scheduling.quartz.JobDetailBean的bean属性“jobClass”

Question

我的项目有一个Quartz调度器，我将JobDetailBean设置为

<bean id="deadlineFailureChecker" class="info.release.scheduler.DeadlineFailureChecker" />

<bean id="workingHourPerDayUpdater" class="info.release.scheduler.WorkingHourPerDayUpdater" />

<bean name="scheduledJob" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass" value="info.release.scheduler.ScheduledJob" />
    <property name="jobDataAsMap">
        <map>
            <entry key="deadlineFailureChecker" value-ref="deadlineFailureChecker" />
            <entry key="workingHourPerDayUpdater" value-ref="workingHourPerDayUpdater" />
        </map>
    </property>     
</bean>

现在，正如我想要将属性值传递给info.release.scheduler.ScheduledJob一样，我做到了：

<bean id="scheduledJobBean" class="info.release.scheduler.ScheduledJob">
    <property name="afrodite" ref="afrodite" />
</bean>

<bean name="scheduledJob" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass">
        <bean factory-bean="scheduledJobBean" factory-method="getClass"></bean>
    </property>
    <property name="jobDataAsMap">
        <map>
            <entry key="deadlineFailureChecker" value-ref="deadlineFailureChecker" />
            <entry key="workingHourPerDayUpdater" value-ref="workingHourPerDayUpdater" />
        </map>
    </property>     
</bean>

但是下面的System.out.println打印的是null

@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
    System.out.println("============================================="+this.afrodite);

}

此方法属于info.release.scheduler.ScheduledJob extends QuartzJobBean。

我还做了一个实验，我设置

<bean id="scheduledJobBean" class="info.release.scheduler.ScheduledJob">
    <property name="afrodite" ref="afrodite" />
</bean> 

至

<bean id="scheduledJobBean" class="info.release.scheduler.ScheduledJob" init-method="init">
    <property name="afrodite" ref="afrodite" />
</bean>

和

public void init() {
    System.out.println("============================================="+this.afrodite);
}

在这个初始化中，System.out.println打印的不是null，而是值。

我不明白这是怎么回事！JobDetailBean是否正在重新实例化jobClass对象？

我需要的是设置JobDetailBean的jobClass属性的值类的属性。

谢谢并致以问候。

我也有同样的问题。我最终将它设为私有静态。如下所示。

private static afrodite;
