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 -->

<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";

trigger.setCronExpression(time);// 触发器时间设定
sched.scheduleJob(jobDetail, trigger);

sched.start();

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();
}
}
}
显示结果：
spring Control层代码中实现定时器管理
