java 定时器

首先在spring-mvc.xml配置文件中配置
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:util="http://www.springframework.org/schema/util" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" 
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:task="http://www.springframework.org/schema/task"//加入这一行
	xsi:schemaLocation="  
	    http://www.springframework.org/schema/util 
	    http://www.springframework.org/schema/util/spring-util-4.1.xsd
	    http://www.springframework.org/schema/mvc 
	    http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
        http://www.springframework.org/schema/beans       
        http://www.springframework.org/schema/beans/spring-beans-4.1.xsd  
        http://www.springframework.org/schema/context   
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
       http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> //加入这一行
其次：<!--cron定时器配置-->
<task:annotation-driven />
在Controller层投放定时器
@Scheduled(cron="0 59 2 ? * FRI")  //每周5凌晨2点59分触发
    public void InsertNewData() {
        LOGGER.info("定时服务启动...");
        try{
                int flag=couponInfoService.insert(); //service层写业务逻辑
        }catch (Exception e){
            e.printStackTrace();
            LOGGER.error("Error msg: "+e.getMessage());
        }
    }
在controller层中加入
private static final Logger LOGGER = Logger.getLogger(CommonController.class);
