springboot整合定时任务

一.创建定时任务类，使用cron表达式
package com.wxit.staservice.scheduled;

import com.wxit.staservice.service.StatisticsDailyService;
import com.wxit.staservice.utils.DateUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.Date;

/**

• @author wj
• @date 2021.12.25 15:14

*/
@Component
public class ScheduledTask {

@Autowired
private StatisticsDailyService statisticsDailyService;

/**
 * 测试
 * 每天七点到二十三点每五秒执行一次
 */
@Scheduled(cron = "0/5 * * * * ?")
public void task1() {
    System.out.println("*********++++++++++++*****执行了");
}

/**
 * 每天凌晨1点执行定时
 */
@Scheduled(cron = "0 0 1 * * ?")
public void task2() {
    //获取上一天的日期
    String day = DateUtil.formatDate(DateUtil.addDays(new Date(), -1));
    statisticsDailyService.registerCount(day);
}

}
二.在启动类上添加注解

package com.wxit.staservice;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.scheduling.annotation.EnableScheduling;

/**

• @author wj
• @date 2021.12.24 14:40

*/
@SpringBootApplication
@ComponentScan(basePackages = {"com.wxit"})
@EnableFeignClients
@EnableDiscoveryClient
@MapperScan("com.wxit.staservice.mapper")
@EnableScheduling //开启定时任务
public class StaApplication {

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

}
