1.在主類上新增EnableScheduling註解

package com.laoxu.gamedog;

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

@EnableScheduling
@SpringBootApplication
public class Application {

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

2.新建定時任務業務類

此處假設為：TestJob

package com.laoxu.gamedog.job;

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

/**
 * 測試定時任務
 *
 * @author xusucheng
 * @create 2018-12-03
 **/
@Component
public class TestJob {
    /**
     * 每5秒鐘執行一次
     */
    @Scheduled(cron = "0/5 * * * * ?")
    public void sayHello(){
        System.out.println("Hello World at "+System.currentTimeMillis());
    }
}
 

3.執行專案，檢視效果
