springboot：spring task定时任务

项目地址：https://github.com/snjl/springboot.springtask.git

创建一个项目，在DemoApplication上加上注解@EnableScheduling：

package com.example.demo;

import com.example.demo.task.Task;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class DemoApplication {
    @Autowired
    private Task task;

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

在demo包里创建Task.java：

package com.example.demo.task;

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

@Component
public class Task {
    private int count=0;

    @Scheduled(cron="*/6 * * * * ?")
    private void process(){
        System.out.println("[" + Thread.currentThread().getName() + "]" + "this is scheduler task runing  "+(count++));
    }

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}

使用@Scheduled注解，就会定时执行。

log日志：

不需要加入其它配置文件和注解。
