本文介绍如何使用Spring框架整合Quartz实现定时任务。通过配置XML文件定义任务调度处理类工厂、表达式触发器工厂及任务调度计划工厂。同时展示了自定义JobFactory和具体定时任务类的实现。

配置xml文件：

<!-- 第一种  -->
    <!-- 任务调度处理类工厂 -->
    <bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.Quartz.TestQuartz"></property>
        <!-- durability 表示任务完成之后是否依然保留到数据库，默认false   -->
        <property name="durability" value="true" /> 

    </bean>
    <!-- 表达式触发器工厂 -->
    <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="jobDetail"></property>
        <property name="cronExpression" value="0/5 * * * * ? "></property>

    </bean>
    <!-- 任务调度计划工厂 -->
    <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="cronTrigger"/>                
            </list>
        </property>
        <!-- 定义使用自己的jobFactory -->
       <property name="jobFactory">
            <bean class="com.Quartz.JobFactory"/>
       </property>
    </bean>

然后自己定义的装配注入类：

package com.Quartz;

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
public class JobFactory extends AdaptableJobFactory {

    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;

    public JobFactory() {

    }

    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        //调用父类
        Object instance = super.createJobInstance(bundle);
        //自动注入
        autowireCapableBeanFactory.autowireBean(instance);
        return instance;
    }
}

用户定时任务类：

import java.util.List;
import java.util.Map;

import javax.annotation.Resource;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;

import com.service.StaffServiceI;

public class TestQuartz extends QuartzJobBean {
    @Resource
    private StaffServiceI staffServiceI;

    @Override
    protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
        // TODO Auto-generated method stub
        List<Map<String,Object>> list=staffServiceI.queryStaffAll();
        for(Map<String,Object> map:list){
            System.out.println(map);
        }
    }


}
