Spring利用TimerTask定时控制

创建自己的TimerTask创建定制的任务

public class CheckEmailAddresses extends TimerTask {

private List emailAddresses;

  public void setEmailAddresses(List emailAddresses) {
    this.emailAddresses = emailAddresses;
  }

  public void run() {
	// iterate over all email addresses and archive them
  }

}

配置：

//具体执行任务的bean

<bean id="checkEmail" class="examples.CheckEmailAddress">

<property name="emailAddresses">

<list>

<value>test@springframework.org</value>

<value>foo@bar.com</value>

<value>john@doe.net</value>
</list>

</property>

</bean>

//配置每个具体任务的信息
<bean id="scheduledTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">

<!-- wait 10 seconds before starting repeated execution -->

<property name="delay" value="10000" />

<!-- run every 50 seconds -->

<property name="period" value="50000" />

<property name="timerTask" ref="checkEmail" />

</bean>

//定制任务Factory，可以将许多不同的任务加入list即可

<bean id="timerFactory" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<!-- see the example above -->
<ref bean="scheduledTask" />
</list>
</property>
</bean>
