### 1、pom.xml增加： ###

<dependency>
        <groupId>org.quartz-scheduler</groupId>
    	<artifactId>quartz</artifactId>
    	<quartz.version>2.2.1</quartz.version>
    </dependency>

### 2、applicationContext.xml中增加如下内容： ###

<bean id="loadReportJobMethod" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">  
    	    <property name="targetObject">
    	        <ref bean="moduleScheduleJob"/>
    	    </property>  
    	    <property name="targetMethod">
    	        <value>moduleSchedule</value>
    	    </property>  
    	</bean> 
    	<bean id="CronTriggerFactoryBean" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">  
    	    <property name="jobDetail" ref="loadReportJobMethod"></property>
    	    <property name="cronExpression" value="0/60 * * * * ?"></property>
    	</bean>
    	<bean id="SpringJobSchedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    	    <property name="triggers">
    	        <list>
    	            <ref bean="CronTriggerFactoryBean"/>
    	        </list>
    	    </property>
    	</bean>

### 3、Java文件（定时任务方法）： ###

package com.iflytek.epdcloud.demc.quartz.job;
    
    @Component
    public class ModuleScheduleJob{
    	//目标方法
    	public void moduleSchedule() {
    		//省略方法内容
       }
    }

### 4、注意问题：ClassNotFoundException: org.springframework.scheduling.quartz.CronTriggerBean ###

#### b、报错原因： ####

是因为quartz的配置信息用的是旧版本、而依赖的确是高版本的jar包  
在quartz 1.8.6及以前版本的时候 调度触发器 依赖的类是 org.springframework.scheduling.quartz.CronTriggerBean  
在2.xx版本之后就改为了org.springframework.scheduling.quartz.CronTriggerFactoryBean  
因此当你依赖2.x.x版本之后只需将调度触发器的依赖类改为 org.springframework.scheduling.quartz.CronTriggerFactoryBean即可
