1、注解作用 @Configuration //主要用于标记配置类,兼备Component的效果。 @EnableScheduling //开启定时任务 @Scheduled(cron = "0/5 * * * * ?") //添加定时任务,每隔5秒执行一次 2、启动项目就可以自动执行了 还有其他的方式,感觉这个最简便 案例如下:
import com.example.demoaa.pojo.City; import com.example.demoaa.service.impl.CityServiceImpl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Configuration; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.scheduling.annotation.Scheduled; import java.util.Date; @Configuration @EnableScheduling public class EnvirMonitSchedule { @Autowired CityServiceImpl cityService; @Scheduled(cron = " 0/5 * * * * ? ") private void test(){ City city = new City(); city.setCityName("aa"); city.setTime(new Date()); cityService.save(city); } }
