Spring Task定时执行

在项目中，我们时常会遇到需要定时去自动执行一串代码的需求

Spring 3.0已经包含了它的坐标 spring-context

第一步， 启动类添加@EnableScheduling开启定时执行

第二步，创建定时任务类

import com.sky.entity.Orders;
import com.sky.mapper.OrderMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import java.time.LocalDateTime;
import java.util.List;

@Component
@Slf4j
public class OrderTask {
@Resource
private OrderMapper orderMapper;
@Scheduled(cron = "0 * * * * ? ")
public void OrderPayTimeOut(){

    LocalDateTime localDateTime=LocalDateTime.now().plusMinutes(-15);
    List<Orders>orders= orderMapper.selectTimeOut(Orders.PENDING_PAYMENT,localDateTime);
    orders.forEach(orders1 -> {
        orders1.setCancelTime(LocalDateTime.now());
        orders1.setStatus(Orders.CANCELLED);
        orders1.setCancelReason("订单超时");
        log.info("订单超时{}",orders1);
        orderMapper.update(orders1);
    });
}
@Scheduled(cron = "0 0 3 * * ? ")

public  void OrderSureTimeOut(){
    log.info("zhengzaizhixing2");
    List<Orders>orders= orderMapper.selectTimeOut(Orders.DELIVERY_IN_PROGRESS,LocalDateTime.now());
    orders.forEach(orders1 -> {
        orders1.setCancelTime(LocalDateTime.now());
        orders1.setStatus(Orders.COMPLETED);
        orders1.setCancelReason("订单确认超时,自动确认");
        log.info("订单确认超时{}",orders1);
        orderMapper.update(orders1);
    });
}

}
