spring时间管理
spring时间管理相比Quartz要简单的多,但功能不如quartz强大
spring.xml的配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <context:component-scan base-package="task"/> </beans>
要执行的任务
package task; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Service; /** * Created by MY on 2017/8/7. */ @Service public class TaskService { //每三秒执行一次 @Scheduled(cron ="0/3 * 17 * * ?") public void print(){ System.out.println("spring任务"); } }
启用任务调动
package task; import org.springframework.context.annotation.Configuration; import org.springframework.scheduling.annotation.EnableScheduling; /** * Created by MY on 2017/8/7. */ @Configuration @EnableScheduling //启用任务调动 public class TaskConfig { }
读取spring.xml文件即可,无需做其他操作
package task; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * Created by MY on 2017/8/7. */ public class SpringTask { public static void main(String[] args) { ClassPathXmlApplicationContext cxt=new ClassPathXmlApplicationContext("spring.xml"); } }
执行结果
