springboot配置定时任务

1. 创建springboot项目
2. 在启动类中添加开启定时任务注解

   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.scheduling.annotation.EnableScheduling;
   
   @SpringBootApplication
   @EnableScheduling // 开启定时任务注解
   public class App {
   
   	public static void main(String[] args) {
   		// TODO Auto-generated method stub
   		SpringApplication.run(App.class, args);
   	}
   
   }

3. 创建定时任务类ScheduledTasks

   import org.springframework.scheduling.annotation.Scheduled;
   import org.springframework.stereotype.Component;
   
   @Component
   public class ScheduledTasks {
   
   	@Scheduled(fixedRate = 2000) // fixedRate:表示以秒为单位，表示2秒执行一次，
   	public void addUser(){
   		System.out.println("-------------添加学生成功----------------");
   	}
   }
   
4. 启动
