Spring定時任務

參考網址：https://spring.io/guides/gs/scheduling-tasks/

1.在Application檔案中添加註解@EnableScheduling

package com.example.demo;

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

@EnableScheduling
@SpringBootApplication
public class DemoApplication {

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

}

2.根據需要建立一個schedulingtasks任務，需要新增@Component和@Scheduled的註解

package com.example.demo.schedulingtasks;

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

import java.util.Date;

@Component
public class ScheduledTasks {

    @Scheduled(fixedDelay = 5000)
    public void reportCurrentTime(){
        System.out.println("當前時間：  " + new Date());
    }
}

 

3.執行專案就行，可在控制檯看到效果
