在項目中有一個需求，需要靈活配置調(diào)度任務(wù)時間，并能自由啟動或停止調(diào)度。?
有關(guān)調(diào)度的實現(xiàn)我就第一就想到了Quartz這個開源調(diào)度組件，因為很多項目使用過，Spring結(jié)合Quartz靜態(tài)配置調(diào)度任務(wù)時間，非常easy。比如：每天凌晨幾點(diǎn)定時運(yùn)行一個程序，這只要在工程中的spring配置文件中配置好spring整合quartz的幾個屬性就好。?

Spring配置文件?

引用
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">?
<property name="targetObject" ref="simpleService" />?
<property name="targetMethod" value="test" />?
</bean>
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">?
<property name="jobDetail" ref="jobDetail" />?
<property name="cronExpression" value="0 0/50 * ? * * *" />?
</bean>?
<bean? id="schedulerTrigger" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">?
<property name="triggers">?
<list>
<ref bean="cronTrigger"/> ?? ??
</list>?
</property>?
</bean>?

這種配置就是對quartz的一種簡單的使用了，調(diào)度任務(wù)會在spring啟動的時候加載到內(nèi)存中，按照cronTrigger中定義的 cronExpression定義的時間按時觸發(fā)調(diào)度任務(wù)。但是這是quartz使用“內(nèi)存”方式的一種配置，也比較常見，當(dāng)然對于不使用spring的項目，也可以單獨(dú)整合quartz。方法也比較簡單，可以從quartz的doc中找到配置方式，或者看一下《Quartz Job Scheduling Framework 》。?

但是對于想持久化調(diào)度任務(wù)的狀態(tài)，并且靈活調(diào)整調(diào)度時間的方式來說，上面的內(nèi)存方式就不能滿足要求了，正如本文開始我遇到的情況，需要采用數(shù)據(jù)庫方式集成 Quartz，這部分集成其實在《Quartz Job Scheduling Framework 》中也有較為詳細(xì)的介紹，當(dāng)然doc文檔中也有，但是缺乏和spring集成的實例。?

一、需要構(gòu)建Quartz數(shù)據(jù)庫表，建表腳本在Quartz發(fā)行包的docs\dbTables目錄，里面有各種數(shù)據(jù)庫建表腳本，我采用的Quartz 1.6.5版本，總共12張表，不同版本，表個數(shù)可能不同。我用mysql數(shù)據(jù)庫，執(zhí)行了Quartz發(fā)行包的docs\dbTables\tables_mysql_innodb.sql建表。?

二、建立java project，完成后目錄如下?
?

三、配置數(shù)據(jù)庫連接池?
配置jdbc.properties文件?

引用
jdbc.driverClassName=com.mysql.jdbc.Driver?
jdbc.url=jdbc:mysql://localhost:3306/quartz?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true?
jdbc.username=root?
jdbc.password=kfs?
cpool.checkoutTimeout=5000?
cpool.minPoolSize=10?
cpool.maxPoolSize=25?
cpool.maxIdleTime=7200?
cpool.acquireIncrement=5?
cpool.autoCommitOnClose=true?

配置applicationContext.xml文件?

引用

<!-- 屬性文件讀入 -->?
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">?
<property name="locations">?
<list>?
<value>classpath:jdbc.properties</value>?
</list>?
</property>?
</bean>?

<!-- 數(shù)據(jù)源定義,使用c3p0 連接池 -->?
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">?
<property name="driverClass" value="${jdbc.driverClassName}" />

<property name="acquireIncrement" value="${cpool.acquireIncrement}" />?
??? <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>???
</bean>

</beans>?

這里只是配置了數(shù)據(jù)連接池，我使用c3p0 連接池，還沒有涉及到Quartx有關(guān)配置，下面且聽我慢慢道來。?

四、實現(xiàn)動態(tài)定時任務(wù)?
? 什么是動態(tài)定時任務(wù)：是由客戶制定生成的，服務(wù)端只知道該去執(zhí)行什么任務(wù)，但任務(wù)的定時是不確定的（是由客戶制定）。?
這樣總不能修改配置文件每定制個定時任務(wù)就增加一個trigger吧，即便允許客戶修改配置文件，但總需要重新啟動web服務(wù)啊，研究了下Quartz在Spring中的動態(tài)定時，發(fā)現(xiàn)?

引用
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean" >?
???????? <property name="jobDetail" ref="schedulerJobDetail"/>?
???????? <property name="cronExpression">?
???????????? <value>0/10 * * * * ?</value>?
???????? </property>?

中cronExpression是關(guān)鍵，如果可以動態(tài)設(shè)置cronExpression的值，就可以順利解決問題了。這樣我們就不能直接使用org.springframework.scheduling.quartz.CronTriggerBean，需要自己實現(xiàn)一個動態(tài)調(diào)度服務(wù)類，在其中構(gòu)建CronTrigger或SimpleTrigger，動態(tài)配置時間。?

SchedulerService 只有一個多態(tài)方法schedule，SchedulerServiceImpl實現(xiàn)SchedulerService接口，注入org.quartz.Schedulert和org.quartz.JobDetail，schedule方法可以動態(tài)配置org.quartz.CronExpression或org.quartz.SimpleTrigger調(diào)度時間。?

五、實現(xiàn)自己的org.quartz.JobDetail?
在上一步中SchedulerServiceImpl需要注入org.quartz.JobDetail，在以前的靜態(tài)配置中?

引用
<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">?
<property name="targetObject" ref="simpleService" />?
<property name="targetMethod" value="testMethod" />?
</bean>

中使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。在這里使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。會報?

引用

異常，google了一下，沒有找到解決方法。所以在這里不能使用org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean。，不能pojo了，需要使用org.springframework.scheduling.quartz.JobDetailBean和org.springframework.scheduling.quartz.QuartzJobBean實現(xiàn)自己的QuartzJobBean，如下：?

Java代碼??

package?com.sundoctor.example.service;??

??

import?org.quartz.JobExecutionContext;??

import?org.quartz.JobExecutionException;??

import?org.quartz.Trigger;??

import?org.springframework.scheduling.quartz.QuartzJobBean;??

??

public?class?MyQuartzJobBean?extends?QuartzJobBean?{??

??

????private?SimpleService?simpleService;??

??????

????public?void?setSimpleService(SimpleService?simpleService)?{??

????????this.simpleService?=?simpleService;??

????}??

??

????@Override??

????protected?void?executeInternal(JobExecutionContext?jobexecutioncontext)?throws?JobExecutionException?{??

????????Trigger?trigger?=?jobexecutioncontext.getTrigger();??

????????String?triggerName?=?trigger.getName();???????

????????simpleService.testMethod(triggerName);??

????}??

??

}??

MyQuartzJobBean繼承org.springframework.scheduling.quartz.QuartzJobBean，注入的SimpleService如下：?

Java代碼??

package?com.sundoctor.example.service;??

??

import?java.io.Serializable;??

??

import?org.slf4j.Logger;??

import?org.slf4j.LoggerFactory;??

import?org.springframework.stereotype.Service;??

??

@Service("simpleService")??

public?class?SimpleService?implements?Serializable{??

??????

????private?static?final?long?serialVersionUID?=?122323233244334343L;??

????private?static?final?Logger?logger?=?LoggerFactory.getLogger(SimpleService.class);??

??????

????public?void?testMethod(String?triggerName){??

????????//這里執(zhí)行定時調(diào)度業(yè)務(wù)??

????????logger.info(triggerName);??

????}??

??????

????public?void?testMethod2(){??

????????logger.info("testMethod2");??

????}??

}??

SimpleService主要執(zhí)行定時調(diào)度業(yè)務(wù)，在這里我只是簡單打印一下log日志。SimpleService需要實現(xiàn)java.io.Serializable接口，否則會報?

引用 Caused by: java.io.InvalidClassException: com.sundoctor.example.service.SimpleService; class invalid for deserialization

dataSource：項目中用到的數(shù)據(jù)源，里面包含了quartz用到的12張數(shù)據(jù)庫表；?
applicationContextSchedulerContextKey： 是org.springframework.scheduling.quartz.SchedulerFactoryBean這個類中把spring上下文以key/value的方式存放在了quartz的上下文中了，可以用applicationContextSchedulerContextKey所定義的key得到對應(yīng)的spring上下文；?
configLocation：用于指明quartz的配置文件的位置，如果不用spring配置quartz的話，本身quartz是通過一個配置文件進(jìn)行配置的，默認(rèn)名稱是quartz.properties，里面配置的參數(shù)在quartz的doc文檔中都有介紹，可以調(diào)整quartz，我在項目中也用這個文件部分的配置了一些屬性，代碼如下：?

引用
org.quartz.scheduler.instanceName = DefaultQuartzScheduler?
org.quartz.scheduler.rmi.export = false?
org.quartz.scheduler.rmi.proxy = false?
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false?

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool?
org.quartz.threadPool.threadCount = 10?
org.quartz.threadPool.threadPriority = 5?
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true?

org.quartz.jobStore.misfireThreshold = 60000?

#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore?

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX?

org.quartz.jobStore.tablePrefix = QRTZ_??
org.quartz.jobStore.isClustered = false??
org.quartz.jobStore.maxMisfiresToHandleAtATime=1?

這里面沒有數(shù)據(jù)源相關(guān)的配置部分，采用spring注入datasource的方式已經(jīng)進(jìn)行了配置。?

這樣只是簡單的將quartz trigger名稱打印出來。?
