spring实现固定时间定时器

此文章是基于  搭建Jquery+SpringMVC+Spring+Hibernate+MySQL平台

 

一. jar包介绍

  1. spring-framework-4.3.4.RELEASE 的 libs 文件夹下得到:

spring-context-support-4.3.4.RELEASE.jar

  2. quartz-2.2.3.jar

 

二. 相关文件介绍

  1. applicationInfrastructure.xml,定时器配置文件

    spring的bean类无法在定时器中自动注入,需要在配置中手动添加 。<property name="jobDataAsMap"

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
    
    <!-- 定义定时器任务  -->
    <bean id="fixTimeJob"
            class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- 指定任务对应的类 -->
        <property name="jobClass" value="com.ims.infrastructure.quartz.FixTimeJob" />
        <!-- 往任务中注入bean  -->        
        <property name="jobDataAsMap">
            <map>
                
            </map>
        </property>    
    </bean>
    
    <!-- 定义任务的触发器 -->
    <bean id="fixTimeJobTrigger" 
            class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">        
        <property name="jobDetail" ref="fixTimeJob" />
        <!-- 重复执行间隔时间(毫秒) -->
        <property name="repeatInterval" value="30000"/>
        <!-- 服务启动后多久执行(毫秒) -->
        <property name="startDelay" value="1000"/>
    </bean>
    
    <!-- 需要被执行的触发器集合 -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="fixTimeJobTrigger"/>
            </list>
        </property>
    </bean>    
    
</beans>

  2. FixTimeJob.java,定时器任务类

package com.ims.infrastructure.quartz;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class FixTimeJob extends QuartzJobBean{
    
    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        System.out.println("hello!");
    }

}
View Code

 

三. 测试
  启动服务,按照定时器配置文件设置的时间间隔,在后台每30秒输出"hello!"
