spring 定时任务的简单使用

 添加依赖 

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <!-- 或者使用webflux -->

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

@EnableAsync
@EnableScheduling
@SpringBootApplication
public class Application {

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

}

@Slf4j
@Component
public class RunTask {

    //cron表达式，每天0点执行
    @Scheduled(cron = "0 0 0 * * ?", zone = "GMT+8")
    public void run() {
        try {
            LocalDateTime dateTime = LocalDateTime.now();
            log.info("》》》》》开始执行任务{} 》》》》》》");
            log.info(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(dateTime));
        } catch (Exception e) {
        }
    }
}
