提示#xff1a;这里可以添加本文要记录的大概内容#xff1a; 提示文章写完后目录可以自动生成如何生成可参考右边的帮助文档 文章目录 前言一、pom的配置1.加注解 二、使用方法1.工程图2.创建工具类 三、controller 实现 前言
提示这里可以添加本文要记录的大概内容 提示以下是本篇文章正文内容下面案例可供参考
一、pom的配置 dependencygroupIdorg.quartz-scheduler/groupIdartifactIdquartz/artifactIdversion2.3.2/version/dependencydependencygroupIdch.qos.logback/groupIdartifactIdlogback-classic/artifactIdversion1.2.3/version/dependency1.加注解
EnableScheduling
public class BusinessApplication {public static void main(String[] args) {SpringApplication.run(BusinessApplication.class, args);log.info(*********启动成功************);}}二、使用方法
1.工程图 2.创建工具类
