# 一、jar 包 #

maven 导包：

<dependency>
    	<groupId>org.springframework</groupId>
    	<artifactId>spring-context-support</artifactId>
    	<version>${spring.version}</version>
    </dependency>
    
    
    <dependency>
    	<groupId>org.quartz-scheduler</groupId>
    	<artifactId>quartz</artifactId>
    	<version>2.3.0</version>
    </dependency>

# 二、配置文件 #

由于需要修改的地方只有三处，直接上代码，代码已经附带了解释，认真看一遍就会了。

    <beans xmlns="http://www.springframework.org/schema/beans"

    	<bean id="taskJob" class="com.quartz.MyJob" />
    	<bean id="jobDetail"
    		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    		<property name="group" value="job_work" />
    		<property name="name" value="job_work_name" />
    		
    		<property name="concurrent" value="false" />
    		<property name="targetObject">

    		</property>
    		<property name="targetMethod">
    		    
    			<value>run</value>
    		</property>
    	</bean>
    	
    	<bean id="myTrigger"
    		class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    		<property name="name" value="work_default_name" />
    		<property name="group" value="work_default" />
    		<property name="jobDetail">
    			<ref bean="jobDetail" />
    		</property>
    		<property name="cronExpression">
    			
    			<value>1-2 0 0-23 * * ? </value>
    		</property>
    	</bean>
    	
    	<bean id="scheduler"
    		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    		<property name="triggers">
    			<list>
    				<ref bean="myTrigger" />
    			</list>
    		</property>
    	</bean>
    </beans>
