一、版本說(shuō)明

spring3.1以下的版本必須使用quartz1.x系列，3.1以上的版本才支持quartz 2.x，不然會(huì)出錯(cuò)。

原因：spring對(duì)于quartz的支持實(shí)現(xiàn)，org.springframework.scheduling.quartz.CronTriggerBean繼承了org.quartz.CronTrigger，在quartz1.x系列中org.quartz.CronTrigger是個(gè)類，而在quartz2.x系列中org.quartz.CronTrigger變成了接口，從而造成無(wú)法用spring的方式配置quartz的觸發(fā)器(trigger)

此示例所選版本：spring版本號(hào)3.0.7.RELEASE，quartz版本1.8.6

二、添加jar包

我的是maven工程，pom.xml相關(guān)配置如下：

UTF-8

3.0.7.RELEASE

1.8.6

org.springframework

spring-context

${spring.version}

commons-logging

commons-logging

org.springframework

spring-context-support

${spring.version}

org.springframework

spring-webmvc

${spring.version}

org.springframework

spring-orm

${spring.version}

jar

compile

org.springframework

spring-test

${spring.version}

jar

test

org.quartz-scheduler

quartz

${quartz.version}

三、整合實(shí)現(xiàn)

1、spring配置

spring只需要添加quartz調(diào)度工廠bean就可以了

2、定時(shí)器工作類實(shí)現(xiàn)

定義定時(shí)器作業(yè)類，該類繼承自job類

package com.ld.nhmz.quartz;

import java.text.SimpleDateFormat;

import java.util.Date;

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

/**

* quartz示例定時(shí)器類

*

* @author Administrator

*

*/

public class QuartzJobExample implements Job {

@Override

public void execute(JobExecutionContext arg0) throws JobExecutionException {

System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) + "★★★★★★★★★★★");

}

}

定義定時(shí)器管理類

package com.ld.nhmz.quartz;

import org.quartz.CronTrigger;

import org.quartz.JobDetail;

import org.quartz.Scheduler;

/**
