使用Spring自带的定时执行任务工具执行任务

1.首先写一个任务类：

@Component("taskJob")

public class DeleteTableRecord {

@Scheduled(cron = "0 0 3 * * ?")

public void job() {

System.out.println("正在执行任务....");

//要执行的任务

System.out.println("任务执行完成.");

}

}

@Scheduled(cron = "0 0 3 * * ?")表示在每天凌晨三点执行任务

@Scheduled(cron = "0 15 3 * * ?")表示每天凌晨三点十五分执行任务

2.在Spring配置文件中加入如下配置:

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:task="http://www.springframework.org/schema/task"

<context:annotation-config />

<!-- 扫描Task所在包-->

<context:component-scan base-package="com.mis.task" />

<!-- Spring支持@Scheduled注解 -->

<task:annotation-driven scheduler="qbScheduler" mode="proxy" />

<!--Task的配置-->

<task:scheduler id="qbScheduler" pool-size="1" />
