SpringBoot定時任務

1. 在啟動類新增註解@EnableScheduling

   `import org.mybatis.spring.annotation.MapperScan;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.cloud.openfeign.EnableFeignClients;
   import org.springframework.scheduling.annotation.EnableScheduling;

   @SpringBootApplication
   @EnableScheduling
   public class MarketingApplication {

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

   }
   `

2. 編寫具體實現,新增@Component和@Scheduled註解

   `import com.joyoung.marketing.service.ChannelSystemService;
   import lombok.extern.slf4j.Slf4j;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.scheduling.annotation.Scheduled;
   import org.springframework.stereotype.Component;

   import java.util.Date;

   /**

   • @author 汪立坤

   • @version 1.0

   • @description

   • @create 2021/3/26

   • /
     @Component
     @Slf4j
     public class SyncSystemChannelSchedule {

     @Autowired
     private ChannelSystemService channelSystemService;
     /**

     • 每天凌晨1點39執行定時任務
     • /
       @Scheduled(cron = “0 39 1 * * ?”)
       public void printSay() {
       log.info(“執行定時任務:{}”,new Date());
       }
       }

   `

3. cron表示式

   六個位置,以空格隔開,依次是秒分時日月周,如果有第七位代表年

   具體用法可以百度
