一、版本说明

spring3.1以下的版本必须使用quartz1.x系列，3.1以上的版本才支持quartz 2.x，不然会出错。

原因：spring对于quartz的支持实现，org.springframework.scheduling.quartz.CronTriggerBean继承了org.quartz.CronTrigger，在quartz1.x系列中org.quartz.CronTrigger是个类，而在quartz2.x系列中org.quartz.CronTrigger变成了接口，从而造成无法用spring的方式配置quartz的触发器（trigger）

此示例所选版本：spring版本号3.0.7.RELEASE，quartz版本1.8.6

二、添加jar包

我的是maven工程，pom.xml相关配置如下：

    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <spring.version>3.0.7.RELEASE</spring.version>        <quartz.version>1.8.6</quartz.version>    </properties>

　　　　　<dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring.version}</version>            <exclusions>                <!-- Exclude Commons Logging in favor of SLF4j -->                <exclusion>                    <groupId>commons-logging</groupId>                    <artifactId>commons-logging</artifactId>                </exclusion>            </exclusions>        </dependency>        <dependency><!--3.0.7没这个包 -->            <groupId>org.springframework</groupId>            <artifactId>spring-context-support</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-orm</artifactId>            <version>${spring.version}</version>            <type>jar</type>            <scope>compile</scope>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-test</artifactId>            <version>${spring.version}</version>            <type>jar</type>            <scope>test</scope>        </dependency>

        <dependency>            <groupId>org.quartz-scheduler</groupId>            <artifactId>quartz</artifactId>            <version>${quartz.version}</version>        </dependency>

三、整合实现

1、spring配置

spring只需要添加quartz调度工厂bean就可以了

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

2、定时器工作类实现

定义定时器作业类，该类继承自job类

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示例定时器类 *  * @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()) + "★★★★★★★★★★★");    }}

定义定时器管理类

package com.ld.nhmz.quartz;import org.quartz.CronTrigger;import org.quartz.JobDetail;import org.quartz.Scheduler;/** * Quartz调度管理器 *  * @author Administrator *  */public class QuartzManager {    private static String JOB_GROUP_NAME = "EXTJWEB_JOBGROUP_NAME";

               Class objJobClass = jobDetail.getJobClass();                removeJob(sched, jobName);                addJob(sched, jobName, objJobClass, time);            }        } catch (Exception e) {            throw new RuntimeException(e);

           }        } catch (Exception e) {            throw new RuntimeException(e);        }    }}

测试代码，这里SchedulerFactory没有使用spring中配置的bean，而是new出来的，做测试用

package com.ld.nhmz.quartz.test;import org.junit.Test;import org.quartz.Scheduler;import org.quartz.SchedulerFactory;import org.quartz.impl.StdSchedulerFactory;import com.ld.nhmz.quartz.QuartzJobExample;import com.ld.nhmz.quartz.QuartzManager;/** * @Description: 测试类 *  * @ClassName: QuartzTest.java */public class QuartzTest {    @Test    public void quartz() {        try {            SchedulerFactory gSchedulerFactory = new StdSchedulerFactory();            Scheduler sche = gSchedulerFactory.getScheduler();            String job_name = "动态任务调度";            System.out.println("【系统启动】开始(每1秒输出一次)...");            QuartzManager.addJob(sche, job_name, QuartzJobExample.class, "0/1 * * * * ?");            Thread.sleep(3000);            System.out.println("【修改时间】开始(每2秒输出一次)...");            QuartzManager.modifyJobTime(sche, job_name, "10/2 * * * * ?");            Thread.sleep(4000);            System.out.println("【移除定时】开始...");            QuartzManager.removeJob(sche, job_name);            System.out.println("【移除定时】成功");            System.out.println("【再次添加定时任务】开始(每10秒输出一次)...");            QuartzManager.addJob(sche, job_name, QuartzJobExample.class, "*/10 * * * * ?");            Thread.sleep(30000);            System.out.println("【移除定时】开始...");            QuartzManager.removeJob(sche, job_name);            System.out.println("【移除定时】成功");        } catch (Exception e) {            e.printStackTrace();        }    }}
