spingboot @EnableScheduling使用

本文主要是介绍spingboot @EnableScheduling使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

springboot让开发更简单！springmvc中启用定时任务还得需要在xml中进行配置启用并且要配置扫描器，但是springboot只需要一个注解就可以。

@EnableScheduling

无需多余的jar依赖，所以pom不贴了

applaction.java

package com.sbm;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;@SpringBootApplication
@EnableScheduling
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}
}

定时任务类AppCoreTask.java

package com.sbm.scheduling;import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.Date;@Component
public class AppCoreTask {@Scheduled(cron = "0 53 15 * * ? ")public void tesk() {System.out.print("开启定时任务" + new Date());}
}

要求在15:53分打印一句话

关于cron表达式的用法，可以在我的这篇文章里查看：Spring Task 中cron表达式整理记录
