定时任务案例

通过定时任务定时检查租约是否到期，SpringBoot内置了定时任务

①、启用SpringBoot定时任务

@SpringBootApplication
@EnableScheduling
public class AdminWebApplication{
	
	public static voin main(String[] args){
		SpringApplication.run(AdminWebApplication.class,args);
	}
}

②、编写定时逻辑
在这里插入图片描述

@Component
public class ScheduledTasks{
	
	@Autowired
	private LeaseArgeementService leaseArgeementService;

	@Scheduled(corn="0 0 0 * * *")
	public void checkLeaseStatus(){
		
		LambdaUpdateWrapper<LeaseArgeement> updateWrapper = new LambdaUpdateWrapper<>();
		Date now = new Date();
		updateWrapper.le(LeaseArgeement::getLeaseEndDate,now);//小于当前日期
		updateWrapper.in(LeaseArgeement::getStatus,LeaseStatus.SIGNED,LeaseStatus.WITHDRAWING);
		updateWrapper.set(LeaseAgreement::getStatus,LeaseStatus.EXPIRED);
		
		service.update(updateWrapper);
	}
}
