Quartz工作排程工具介紹(二)-與Spring整合

開始前的版本說明:我的Spring為4.1.6版,Quartz為 2.2.1

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"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

    ">
     
     <bean id="targetClass" class="com.gorilla.util.quartz.PageStatisticJob"/>
     
     <bean id="targetKeywordStatisticJob" class="com.gorilla.util.quartz.KeywordStatisticJob"/>
     

 <bean id="jobPageStatistic" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
     <property name="targetObject" ref="targetClass"/>
     <property name="targetMethod" value="execute"/>
 </bean>
 
 <bean id="jobKeywordStatistic" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
     <property name="targetObject" ref="targetKeywordStatisticJob"/>
     <property name="targetMethod" value="execute"/>
 </bean>


     <!-- Run the job every 15 minutes  -->
 <bean id="cronTrigger"  class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
     <property name="jobDetail" ref="jobPageStatistic" />
     <property name="cronExpression" value="0 0/10 * * * ?"  />
 </bean>
 
 <bean id="cronTrigger2"  class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
     <property name="jobDetail" ref="jobKeywordStatistic" />
     <property name="cronExpression" value="0 0/11 * * * ?"  />
 </bean>
 
 
 
     
 <!--  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>

        <property name="quartzProperties">
            <props>
                <prop key="org.quartz.scheduler.instanceName">EYMSheduler</prop>
                <prop key="org.quartz.threadPool.threadCount">5</prop> <!-- 可執行job的thread數量 -->
                <prop key="org.quartz.jobStore.class">org.quartz.simpl.RAMJobStore</prop>
                <prop key="org.quartz.plugin.triggHistory.class">org.quartz.plugins.history.LoggingTriggerHistoryPlugin</prop>
                <prop key="org.quartz.plugin.triggHistory.triggerFiredMessage">
                    Trigger [{1}.{0}] fired job [{6}.{5}] scheduled at: {2, date, yyyy-MM-dd HH:mm:ss.SSS}, next scheduled at: {3, date, yyyy-MM-dd HH:mm:ss.SSS}
                </prop>
                <prop key="org.quartz.plugin.triggHistory.triggerCompleteMessage">
                    Trigger {1}.{0} completed firing job {6}.{5} at {4, date, yyyy-MM-dd HH:mm:ss.SSS} with resulting trigger instruction code: {9}
                </prop>

                <prop key="org.quartz.plugin.triggHistory.triggerMisfiredMessage">
                    Trigger {1}.{0} misfired job {6}.{5} at: {4, date, yyyy/MM/dd HH:mm:ss }. Should have fired at: {3, date,yyyy/MM/dd HH:mm:ss}
                </prop>
                <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" />

Tomcat 8 增加虛擬目錄

     在 apache-tomcat 安裝目錄下的 \conf底下,找到server.xml檔案,在Host標籤內,增加
<Context>節點,例如:
<Context docBase="C:\actualDirectory" path="/virtualDirectory" reloadable="true"/> ,此節點是將
實體目錄與虛擬目錄做mapping的設定,完成後重啟tomcat 。
     接下來可以試著將檔案放置到虛擬目錄C:\actualDirectory,例如放置一個圖檔example.jpg,
則可以用下面的方式存取到example.jpg圖檔:
http://192.168.11.100/virtualDirectory/example.jpg
