SpringBoot-定时任务

springboot-定时任务

everthing will be okay....

实现结果如下：

1. 添加依赖包

<dependencies>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter</artifactId>
	</dependency>
</dependencies>

2. 添加相关注释

   @SpringBootApplication
   @EnableScheduling
   public class Application {
   
   	public static void main(String[] args) {
   		SpringApplication.run(Application.class, args);
   	}
   }
   

3. 定时任务实现（CRON表达式与自定义时间）

   package com.empirefree.component;
   
   import org.springframework.scheduling.annotation.Scheduled;
   import org.springframework.stereotype.Component;
   
   /**
    * @ProjectName: SchedulerTask
    * @Package: com.empirefree.component
    * @Description:
    * @Author: huyuqiao
    * @CreateDate: 2020/10/12 16:01
    */
   @Component
   public class SchedulerTask {
   
       private int count=0;
   
       @Scheduled(cron="*/6 * * * * ?")
       private void process(){
           System.out.println("this is scheduler task runing  "+(count++));
       }
   
   }
   

   package com.empirefree.component;
   
   import org.springframework.scheduling.annotation.Scheduled;
   import org.springframework.stereotype.Component;
   
   import java.text.SimpleDateFormat;
   import java.util.Date;
   
   /**
    * @ProjectName: Scheduler2Task
    * @Package: com.empirefree.component
    * @Description:
    * @Author: huyuqiao
    * @CreateDate: 2020/10/12 16:01
    */
   @Component
   public class Scheduler2Task {
   
       private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
   
       @Scheduled(fixedRate = 6000)
       public void reportCurrentTime() {
           System.out.println("现在时间：" + dateFormat.format(new Date()));
       }
   
   }
