1.采用加注解方式      在方法上加@PostConstruct

//读取阻塞队列,多线程执行
        @PostConstruct
        public void refundOrder() {
            System.out.println("启动tomcat时自动调用");
            RBlockingDeque<String> blockingDeque = redissonClient.getBlockingDeque("jiuyang_order_message");
            scheduledThreadPoolExecutor.execute(new SendingTask(blockingDeque));
    
            RBlockingDeque<String> blockingDeque2 = redissonClient.getBlockingDeque("jiuyang_order_zhang");
            scheduledThreadPoolExecutor.execute(new SendingTask(blockingDeque2));
        }

2.采用实现ApplicationRunner接口.重写run方法 ,run方法调用的方法都会在启动tonmcat是时执行

import com.cncbox.mall.consumer.service.impl.RefundOrderServiceImpl;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.ApplicationArguments;
    import org.springframework.boot.ApplicationRunner;
    import org.springframework.stereotype.Component;
    
    /**
     * @author : zhang sq

     **/
    
    @Component
    public class ApplicationRunnerImpl implements ApplicationRunner {
    
        @Autowired
        private RefundOrderServiceImpl refundOrderService;
    
        //tomcat启动执行此方法
        @Override
        public void run(ApplicationArguments args) throws Exception {
            refundOrderService.refundOrder(); //正常订单超时未付款自动关闭
            refundOrderService.automatic(); //自动收货
            refundOrderService.comment();  //自动好评
        }
    }
