spring boot中使用定时任务
1.在主类上添加EnableScheduling注解
package com.laoxu.gamedog;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@EnableScheduling
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
2.新建定时任务业务类
此处假设为:TestJob
package com.laoxu.gamedog.job;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
/**
* 测试定时任务
*
* @author xusucheng
* @create 2018-12-03
**/
@Component
public class TestJob {
/**
* 每5秒钟执行一次
*/
@Scheduled(cron = "0/5 * * * * ?")
public void sayHello(){
System.out.println("Hello World at "+System.currentTimeMillis());
}
}
3.运行项目,查看效果
