Java SpringBoot学习笔记 53 定时执行任务

1. 启动类增加注解 @EnableScheduling

package com.example.springboot09async;

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

@EnableAsync
@EnableScheduling
@SpringBootApplication
public class Springboot09AsyncApplication {

	public static void main(String[] args) {
		SpringApplication.run(Springboot09AsyncApplication.class, args);
	}

}

2. 增加定时任务类 ScheduledService.java

package com.example.springboot09async.service;

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

@Service
public class ScheduledService {

	/**
	 * 每隔10秒钟执行一次
	 */
	@Scheduled(cron = "0/10 * * * * ?")
	public void hello() {
		System.out.println("每一个不曾起舞的日子，都是对生命的辜负。");
	}
	
}
