第二种配置方式   注解配置定时任务

spring-timer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:task="http://www.springframework.org/schema/task"
   xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans.xsd 
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-4.0.xsd 
   http://www.springframework.org/schema/task
   http://www.springframework.org/schema/task/spring-task-4.0.xsd
   http://www.springframework.org/schema/mvc 
   http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

 <task:executor id="executor" pool-size="5" />  
    <task:scheduler id="scheduler" pool-size="10" />  
    <task:annotation-driven executor="executor" scheduler="scheduler" />
</beans>



任务类  注解启动
      
@Component（把普通pojo实例化到spring容器中，相当于配置文件中的<bean id="" class=""/>）      
public class ToTimer{

   @Resource
   RoleService roleService;
@Scheduled(cron = "0/20 * * * * ? ")
   public void run() {
      /**
       * 调用存储过程，重新创建表，插入初始化数据。
       */
      roleService.initData();
      System.out.println(new Date().getTime());
   }
}
ssm定时器

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

springboot定时器   总的来说   注解定时器最为方便 

在springboot核心类中加入@EnableScheduling即可，表示支持定时任务
