1.scheduled定时任务类:ScheduledDemo.java
package com.nantian.scheduled;
import java.util.Date;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
/**
* scheduled定时任务
*@author xjj13
*@component （把普通pojo实例化到spring容器中，相当于配置文件中的
*<bean +new Date());
}
}
2.在启动类中开启定时任务的启用
springBoot中默认是对scheduled是不开启的
@SpringBootApplication
@EnableScheduling//开启scheduled定时任务
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
