Only no-arg methods may be annotated with @Scheduled 的解决方法

问题描述

今天在写爬虫代码时，需要个定时抓取任务，测试时SpringBoot项目启动时报错，记录一下问题

Only no-arg methods may be annotated with @Scheduled

控制台输出错误日志：

Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'commentSubmit': Only no-arg methods may be annotated with @Scheduled

原因分析：

报错的大致意思是使用@Scheduled注解的方法不能带参数，看了下自己的代码，确实存在这个问题，那就很好解决了

解决方案：

1、可以选择不适用SpringBoot自带Scheduler，使用xml配置等其他方式实现定时任务

2、如果确定使用Scheduler，那只有根据自己的业务需求改造方法了
