Spring中使用Quartz的两种方式

作业类是否继承QuartzJobBean

MethodInvokingJobDetailFactoryBean

JobDetailFactoryBean

任务调度的触发时机

这两种触发方式都可以和两种作业继承方式相互组合来使用。

也就是有四种写法。

举个例子：

不继承QuartzJobBean，由SimpleTriggerBean触发

<bean id="simpleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="myBean"/>
<property name="targetMethod" value="printMessage"/>
</bean>

<!-- Run the job every 2 seconds with initial delay of 1 second -->
<bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
<property name="jobDetail" ref="simpleJobDetail"/>
<property name="startDelay" value="1000"/>
<property name="repeatInterval" value="2000"/>
</bean>

public class MyBean {

public void printMessage(){
System.out.println("不继承QuartzJobBean的作业类。called by MethodInvokingJobDetailFactoryBean using SimpleTriggerFactoryBean");
}
}

不继承QuartzJobBean，由CronTriggerBean触发

继承QuartzJobBean，由SimpleTirggerBean触发

继承QuartzJobBean，由CronTriggerBean触发

public class ScheduledJob extends QuartzJobBean {

private AnotherBean anotherBean;

protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
anotherBean.printMessage();
}

public void setAnotherBean(AnotherBean anotherBean) {
this.anotherBean = anotherBean;
}
}

public class AnotherBean {
public void printMessage(){
System.out.println("继承QuartzJobBean的作业类，通过AnotherBean传递数据。called by JobDetailFactoryBean using CronTriggerFactoryBean");
}
}

<!-- For times when you need more complex processing, passing data to the scheduled job -->
<bean name="complexJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="jobClass" value="com.penelope.quickstart.jobs.ScheduledJob"/>
<property name="jobDataAsMap">
<map>
<entry key="anotherBean" value-ref="anotherBean"/>
</map>
</property>
<property name="durability" value="true"/>
</bean>

<!-- Run the job every 5 seconds only on Weekends -->
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="complexJobDetail"/>
<property name="cronExpression" value="0/5 * * ? * SAT-SUN"/>
</bean>
