SpringBoot定时任务

代码做定时任务：1、开个线程，线程里面休眠去做

　　　　　　　　2、使用一些定时任务的框架去做

1、创建TimerTest类

package com.cppdy.service;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class TimerTest {
    
    @Scheduled(fixedRate=2000)
    public void showTime() {
        System.out.println("当前时间戳："+System.currentTimeMillis());
    }

}

2、在Application类中开启定时任务（@EnableScheduling）

package com.cppdy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class Application {
    
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}
