<!-- 测试spring定时器是否能用 -->
<bean id="testSpringTimeService" class="com.blit.service.impl.TestSpringTimeServiceImpl"></bean>

<task:scheduled-tasks>
<!-- 每天5s执行一次 -->
<task:scheduled ref="testSpringTimeService" method="testQuart" cron="0/5 * * * * ?"/>  /*百度spring定时器表达式*/

TestSpringTimeServiceImpl实现类：

package com.blit.service.impl;

public class TestSpringTimeServiceImpl {
    public void testQuart(){

        /*定时器所做的逻辑处理*/
        System.out.println("Spring 定时器每5秒触发一次！！！！！！");
    }
}
