@Scheduled(cron)报错导致项目启动不了_scheduled 报错-优快云博客

本文记录了一次在SpringBoot项目中遇到的定时任务Cron表达式错误，错误信息指出cron表达式必须由6位组成，但实际编写时包含了7位。通过对错误的分析，了解到SpringBoot内置的定时任务不支持包含年的cron表达式，并进行了修正。解决方案是删除非必需的年份字段，从而解决了问题。此外，还探讨了引入Quartz作为替代方案的可能性。

在查看报错日志时注意到:Cron expression must consist of 6 fields (found 7 in “0 0 3 1 9 ? *”) 大概意思是cron表达式必须由6位组成 ,在我写的表达式里发现了 7位 . 对此甚是不解,但是还是根据报错的原因把非必填的年删掉了.结果可以了.
在网上查询后大概的原因是:springboot内置的定时任务的cron表达式不支持年要是需要年 ;可以引入quartz
