Spring设置定时器配置

corn表达式生成：http://www.pppet.net/

1.注解方式

添加命名空间

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

http://www.springframework.org/schema/task

http://www.springframework.org/schema/task/spring-task-4.0.xsd

task任务扫描注解

<task:annotation-driven/>

spring扫描位置

<context:annotation-config/>

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

定时任务

@Scheduled(cron="0/5 * * * * ? ") //每5秒执行一次

public void myTest(){

System.out.println("进入测试");

} 

注意：定时器的任务方法不能有返回值（如果有返回值，spring初始化的时候会告诉你有个错误、需要设定一个proxytargetclass的某个值为true）

2.xml方式

<?xml version="1.0" encoding="UTF-8"?>
