12. SpringBoot定时任务

SpringBoot定时任务

1. 定时任务配置

   package com.demo.scheduled;
   
   import org.springframework.scheduling.annotation.Scheduled;
   import org.springframework.stereotype.Component;
   
   import java.util.Date;
   
   @Component
   public class MySchedule {
       @Scheduled(fixedDelay = 1000)
       public void fixedDelay(){
           System.out.println("fixed delay:"+new Date());
       }
       @Scheduled(fixedRate = 2000)
       public void fixedRate(){
           System.out.println("fixed rate:"+new Date());
       }
       @Scheduled(initialDelay = 1000,fixedRate = 2000)
       public void initialDelay(){
           System.out.println("initial delay:"+new Date());
       }
       @Scheduled(cron="0 */1 * * * ?")
       public void cron(){
           System.out.println("cron: "+new Date());
       }
   }
   

2. 开启定时日志

   // 在SpringBoot启动类上添加注解
   @EnableScheduling
