实现任务类:
package com.vnetoo.nec.base.quartz;
import org.springframework.context.annotation.Lazy;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
/**
* 定时发送信息
*
* @author lingpy
* @since 1.0
*/
@Component
@Lazy(false)
public class SendMessageJob{
private static long time = 0;
@Scheduled(cron="0 0/2 * * * ? ") //两分钟一次
public void work(){
time++;
System.out.println("SendMessageJob : send message " + time + ",current :" + System.currentTimeMillis());
}
}
spring.xml 配置
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.1.xsd
">
<task:annotation-driven/><!-- task任务扫描注解 -->
spring.xml可以添加注解扫描的配置
xmlns:context="http://www.springframework.org/schema/context
xsi:schemaLocation="
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
">
<context:component-scan base-package="com.vnetoo.nec" />
主要事项:
在Spring配置和Quartz集成内容时,有两点需要注意
1、在<Beans>中不能够设置default-lazy-init="true",否则定时任务不触发,如果不明确指明default-lazy-init的值,默认是false。可使用@Lazy(false)显示确定
2、在<Beans>中不能够设置default-autowire="byName"的属性,否则后台会报 org.springframework.beans.factory.BeanCreationException错误,这样就不能通过Bean名称自 动注入,必须通过明确引用注入
