spring 中集成quartz定时器及quartz中cronExpression配置说明



spring 中集成quartz：

spring文件的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans

	<bean id="quartzFactoryBean" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

	</bean>

	<bean id="cronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="quartzFactoryBean"/>
		</property>
		<!--
			一个cron表达式有至少6个（也可能7个）有空格分隔的时间元素
			按顺序依次为:秒、分、时、日、月、周、年
			注：由于"月份中的日期"和"星期中的日期"这两个元素互斥的,必须要对其中一个设置为?
		 -->
		<property name="cronExpression">
			<value>0/5 * * * * ?</value>
		</property>
	</bean>

	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="cronTriggerBean"/>
			</list>
		</property>
	</bean>
</beans>

定时器执行的java类：

package com.chen.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

public class QuartzTask {

	static int count = 0;

	public void executeQuartzTask(){
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
		System.out.println(sdf.format(new Date())+":"+count++);
	}
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println(count++);
		System.out.println(count++);
	}

}
