我这边项目的需求是：每天晚上1点删除数据库表t\_tempclob中的所有记录；

代码：

Controller：

@Controller
    public class AjaxFileDownload {
        
        private static Logger logger = Logger.getLogger(AjaxFileDownload.class);
        
        @Autowired
        private ProductService productService;
        
        @Autowired
        private TempClobService tcService;
        
        /**
         * 定时任务，每天晚上1点删除数据表t_tempClob中的所有记录
         */
        @Scheduled(cron= "0 0 1 * * ?")
        public void deleteAllTempClob(){
            int count = tcService.deleteAllTempClob();
            System.err.println("---->>deleteAllTempClob删除数据库记录数:" + count);
        }
    }
