SpringBoot整合定时任务之实现Scheduled注解的过程(一个注解全解决)

<dependency>

package com.wang.test.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling//启动定时任务
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

package com.wang.test.demo.task;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component//加载到容器中,可以被发现启动
public class TaskTest {

    //cron表达式,来控制定时执行时间,这里是每5秒执行一次本方法,业务逻辑可以进行在此方法内进行书写
    @Scheduled(cron = "0/5 * * * * ?")
    public void printTimeOne(){

        System.out.println("任务一:时间为-->"+System.currentTimeMillis());
    }

    @Scheduled(cron = "0/6 * * * * ?")
    public void printTimeTwo(){

        System.out.println("任务二:时间为-->"+System.currentTimeMillis());

    }

}
