錯誤代碼：

@Component
public class AutoShelfSchedule {

    @Autowired
    IntegralGoodsService service;

    @Scheduled(cron = "0 30 14 * * ? *")
    public void dealShelf(){
        System.out.println("定時任務 : 自動上下架處理--->開始");

 

 

 

錯誤原因：

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

也就是說，這個解析cron的地方，只支持六位。

 

解決方法：

去掉一位即可

@Component
public class AutoShelfSchedule {

    @Autowired
    IntegralGoodsService service;

    @Scheduled(cron = "0 35 14 * * ?")
    public void dealShelf(){
        System.out.println("定時任務 : 自動上下架處理--->開始");
