Spring定时器

在配置文件 applicationContext.xml 中添加

...
    xmlns:task="http://www.springframework.org/schema/task"
    ...
    xsi:schemaLocation="
    ...
    http://www.springframework.org/schema/task
    http://www.springframework.org/schema/task/spring-task-3.2.xsd">

    

    
    "com.test" annotation-config="true" />

    

类

package com.test.scheduled;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Lazy;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component("ScheduledManager")
@Lazy(value=false)
public class ScheduledManager {

    /**
     * 定时任务
     */
    @Scheduled(initialDelay = 1000*60*10, fixedRate = 1000*60*10)
    public void task(){
        System.out.print("定时任务");
    }

}

Spring 4.x 中需在类名前加@EnableScheduling
@Scheduled中可使用cron表达式和fixedDelay
