1. 準備好要被排程的job Bean，由於我這邊使用的是org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean 這個Class，因此我要被排程的程式不需要去implements org.quartz.Job，使用一般的Bean即可，我的Bean為KeywordStatisticJob，要被執行的方法為execute()，準備好要被排程的程式後，可以開始設定spring-quartz.xml。
2.我的spring-quartz.xml如下:
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"

<prop key="org.quartz.jobStore.misfireThreshold">500</prop>
</props>
</property>
<property name="overwriteExistingJobs" value="true" />
</bean>
</beans>
這邊稍微說明一下設定檔的內容:a. 首先先將job bean定義如下
<bean id="targetKeywordStatisticJob" class="com.gorilla.util.quartz.KeywordStatisticJob"/>
b.接著新增一個MethodInvokingJobDetailFactoryBean這樣的類別設定如下:
<bean id="jobKeywordStatistic" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="targetKeywordStatisticJob"/>
<property name="targetMethod" value="execute"/>
</bean>
其中 targetObject 這個屬性是去參考到要執行的Job類別的 Bean Id，targetMethod參考到job要被排程執行的method name，這裡為execute。
c.再新增一個CronTrigger類別的Bean，如下設定:
<bean id="cronTrigger2" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="jobKeywordStatistic" />
<property name="cronExpression" value="0 0/10 * * * ?" />
</bean>
這個cronTrigger物件有兩個屬性，一個為jobDetail，指定他要排程的目標為jobKeywordStatistic，cronExpression屬性則是設定多久執行一次目標，這邊設定為每11分鐘執行一次jobKeywordStatistic。
d.最後指定我們的schedulerFactory Bean，並且設定它，將上述的MethodInvokingJobDetailFactoryBean以及CronTriggerFactoryBean分別設定置它的schedulerFactory Bean的jobDetails property以及triggers propety，如下:
<!-- scheduler factory -->
<bean id="schedulerFactory" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="jobDetails">
<list>
<ref bean="jobPageStatistic" />
<ref bean="jobKeywordStatistic" />
</list>
</property>
<property name="triggers">
<list>
<ref bean="cronTrigger" />
<ref bean="cronTrigger2" />
</list>
</property>
e.最後將spring-quartz.xml import進 spring.xml，即完成整個設定，設定如下:
<import resource="classpath:conf/spring-quartz.xml" />
