错误代码：

@Component
public class AutoShelfSchedule {

    @Autowired
    IntegralGoodsService service;

    @Scheduled(cron = "0 30 14 * * ? *")
    public void dealShelf(){
        System.out.println("定时任务 : 自动上下架处理--->开始");

错误原因：

Spring Task是Quartz的弱版，quartz支持年份，而Spring Task不支持。

也就是说，这个解析cron的地方，只支持六位。

解决方法：

去掉一位即可

@Component
public class AutoShelfSchedule {

    @Autowired
    IntegralGoodsService service;

    @Scheduled(cron = "0 35 14 * * ?")
    public void dealShelf(){
        System.out.println("定时任务 : 自动上下架处理--->开始");
