spring 注解方式配置定时任务

傷城~ 2022-07-14 09:48 207阅读 0赞

在applicationContext.xml中配置

<task:annotation-driven/>

同时确保扫描程序能够扫描后定时器类

<context:component-scan base-package="xiaobao"/>

注解类：AnnotationQuartz.java

import org.springframework.scheduling.annotation.Scheduled;  
    import org.springframework.stereotype.Component;  
    import java.util.Date;    
    @Component  
    public class AnnotationQuartz {  
        @Scheduled(cron = "0 0/1 15,* * * ?")  
        //需要注意@Scheduled这个注解，它可配置多个属性：cron\fixedDelay\fixedRate  
        public void test() {  
           System.out.println(System.currentTimeMillis());
        }  
    }
