spring实现定时任务之Timer

Task:
public class SayHelloTask extends TimerTask
{
    @Override
    public void run()
    {
        System.out.println(" timer ");
        
    }
}

 

程序调用：
public static void main(String[] args)
{
    Timer timer=new Timer();
    timer.scheduleAtFixedRate(new SayHelloTask(),0, 3000);
}

 

 


spring 配置：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
    <bean name="sayHelloTask" class="com.timer.SayHelloTask"></bean>

    <bean id="scheduledTask"　class="org.springframework.scheduling.timer.ScheduledTimerTask">
        <property name="timerTask">
            <ref bean="sayHelloTask" />
        </property>
        <!-- 任务执行周期 2m 关于一些任务的参数请参考JDK doc文档和Spring相关文档-->
        <property name="period">
            <value>5000</value>
        </property>
        <!-- 延时1m 执行任务 -->
        <property name="delay">
            <value>1000</value>
        </property>
    </bean>
    <!-- 启动定时器 -->
    <bean id="timerBean" class="org.springframework.scheduling.timer.TimerFactoryBean">
        <property name="scheduledTimerTasks">
            <list>
                <ref bean="scheduledTask" />
            </list>
        </property>
    </bean>

</beans>
