我的项目有一个Quartz调度程序,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>
现在我想将一个属性值传递给我做的info.release.scheduler.ScheduledJob:
<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>
但以下System.out.println
正在打印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
。
我也做了一个实验,我设置了
<bean id="scheduledJobBean" class="info.release.scheduler.ScheduledJob">
<property name="afrodite" ref="afrodite" />
</bean>
要
<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);
}
在此init中,System.out.println
不打印null而是打印值。
我无法理解发生了什么! JobDetailBean是否重新实例化jobClass对象?
我需要设置jobClass
JobDetailBean
属性的值类的属性。
谢谢和问候。

我也是同一个问题。我最终将其设为私有静态。如下所示
private static afrodite;
