定时器(quartz和线程的使用)

 

quartz

一、引入两个jar包

spring-context-support-3.0.2.RELEASE.jar、quartz.jar

 

二、配置文件：applicationContext.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"

    xmlns:jaxws="http://cxf.apache.org/jaxws"

    xsi:schemaLocation="

            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd

            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

            http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd

            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd

            http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd

            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd

            http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

    <!-- ======================== 类方法 ======================== -->

    <bean id="vehChangeStatusQueueJob" class="org.springframework.scheduling.quartz.JobDetailBean">

        <property name="jobClass" value="testwebapp.com.wangzuojia.schedule.ScheduleTest"/>

        <!-- <property name="jobDataAsMap">

            <map>

                <entry key="autoCommonBsh2014" value-ref="autoCommonBsh2014"/>

                <entry key="changeStatusQueueBsh" value-ref="changeStatusQueueBsh"/>

            </map>

        </property> -->

    </bean>

    <!-- ======================== 触发器 ======================== -->

    <bean id="vehChangeStatusQueueCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">

        <property name="jobDetail" ref="vehChangeStatusQueueJob" />

        <property name="cronExpression" value="2/3 * * * * ?" />

    </bean>

    <!-- ======================== 调度工厂 ======================== -->  

    <bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">  

        <property name="triggers">  

            <list>  

                <ref bean="vehChangeStatusQueueCronTrigger"/>  

            </list>  

        </property>  

    </bean>    

 

</beans>

 

三、测试类ScheduleTest 

package testwebapp.com.wangzuojia.schedule;

 

import java.util.Date;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

import org.springframework.scheduling.quartz.QuartzJobBean;

 

public class ScheduleTest extends QuartzJobBean {

    @Override

    protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {

        System.out.println("Schedule start at:"+ new Date());

    }

}

线程

一、配置文件(applicationContext.xml)中扫描定时器

　　<!-- 扫描定时器 -->
　　<context:component-scan base-package="com.util.thread" />

二、定期器的类

package com.util.thread;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;

import com.util.UtilDate;

@Service("jobServiceTwo")
public class AttentionTime {
　　// <!-- 早9点到晚9点每10分钟运行一次 -->
　　@Scheduled(cron = "0 0/10 9-21 * * ?")
　　public void job1() {
　　　　System.out.println("----定时任务：10分钟执行一次----" + UtilDate.getDateFormatter());
　　}
}
