Maven的pom.xml的配置：

特别注意一点，与Spring3.1以下版本整合必须使用Quartz1，最初我拿2.1.3的，怎么搞都报错：
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.scheduling.quartz.CronTriggerBean]
for bean with name 'mytrigger' defined in class path resource [applicationContext.xml]:
problem with class file or dependent class;
nested exception is java.lang.IncompatibleClassChangeError:
class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class
查看发现spring3.0.5中org.springframework.scheduling.quartz.CronTriggerBean继承了org.quartz.CronTrigger（public class CronTriggerBeanextends CronTrigger），
而在quartz2.1.3中org.quartz.CronTrigger是个接口（publicabstract interface CronTrigger extends Trigger），
而在quartz1.8.5及1.8.4中org.quartz.CronTrigger是个类（publicclass CronTrigger extends Trigger），从而造成无法在applicationContext中配置触发器。
这是spring3.1以下版本和quartz2版本不兼容的一个bug。（感谢tiren的回复，spring3.1以及以后版本支持quartz2）
在Spring中使用Quartz有两种方式实现：
第一种是任务类继承QuartzJobBean，
第二种则是在配置文件里定义任务类和要执行的方法，类和方法仍然是普通类。
很显然，第二种方式远比第一种方式来的灵活。
第一种方式的JAVA代码：
package com.ncs.hj;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
public class SpringQtz extends QuartzJobBean{
private static int counter = 0;
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
System.out.println();
long ms = System.currentTimeMillis();
System.out.println("\t\t" + new Date(ms));
System.out.println(ms);
System.out.println("(" + counter++ + ")");
String s = (String) context.getMergedJobDataMap().get("service");
System.out.println(s);
System.out.println();
}
}
第二种方式的JAVA代码：
package com.ncs.hj;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
import java.util.Date;
public class SpringQtz {
private static int counter = 0;
protected void execute() {
long ms = System.currentTimeMillis();
System.out.println("\t\t" + new Date(ms));
System.out.println("(" + counter++ + ")");
}
}
Spring的配置文件：
<!------------ 配置调度程序quartz ，其中配置JobDetail有两种方式-------------->
<!--方式一：使用JobDetailBean，任务类必须实现Job接口 -->
<bean id="myjob" class="org.springframework.scheduling.quartz.JobDetailBean">
<property name="name" value="exampleJob"></property>
<property name="jobClass" value="com.ncs.hj.SpringQtz"></property>
<property name="jobDataAsMap">
<map>
<entry key="service"><value>simple is the beat</value></entry>
</map>
;/property>
</bean>
<!--运行时请将方式一注释掉！ -->
<!-- 方式二：使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->
<!-- 定义目标bean和bean中的方法 -->
<bean id="SpringQtzJob" class="com.ncs.hj.SpringQtz"/>
<bean id="SpringQtzJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject">
<ref bean="SpringQtzJob"/>
</property>
<property name="targetMethod"> <!-- 要执行的方法名称 -->
<value>execute</value>
</property>
</bean>
<!-- ======================== 调度触发器 ======================== -->
<bean id="CronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="SpringQtzJobMethod"></property>
<property name="cronExpression" value="0/5 * * * * ?"></property>
</bean>
<!-- ======================== 调度工厂 ======================== -->
<bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="CronTriggerBean"/>
</list>
</property>
</bean>
最后别忘了在web.xml里面配置Spring：
