Quartz 在 Spring 中如何动态配置时间

發布時間:2025/7/14 javascript 25 豆豆
生活随笔 收集整理的這篇文章主要介紹了 Quartz 在 Spring 中如何动态配置时间 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在項目中有一個需求,需要靈活配置調度任務時間,并能自由啟動或停止調度。
有關調度的實現我就第一就想到了Quartz這個開源調度組件,因為很多項目使用過,Spring結合Quartz靜態配置調度任務時間,非常easy。比如:每天凌晨幾點定時運行一個程序,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,調度任務會在spring啟動的時候加載到內存中,按照cronTrigger中定義的 cronExpression定義的時間按時觸發調度任務。但是這是quartz使用“內存”方式的一種配置,也比較常見,當然對于不使用spring的項目,也可以單獨整合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度任務的狀態,并且靈活調整調度時間的方式來說,上面的內存方式就不能滿足要求了,正如本文開始我遇到的情況,需要采用數據庫方式集成 Quartz,這部分集成其實在《Quartz Job Scheduling Framework 》中也有較為詳細的介紹,當然doc文檔中也有,但是缺乏和spring集成的實例。

一、需要構建Quartz數據庫表,建表腳本在Quartz發行包的docs/dbTables目錄,里面有各種數據庫建表腳本,我采用的Quartz 1.6.5版本,總共12張表,不同版本,表個數可能不同。我用mysql數據庫,執行了Quartz發行包的docs/dbTables/tables_mysql_innodb.sql建表。

二、建立java project,完成后目錄如下
?

三、配置數據庫連接池
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
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

?
?? <context:component-scan base-package="com.sundoctor"/>

<!-- 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>

<!-- 數據源定義,使用c3p0 連接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${jdbc.driverClassName}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialPoolSize" value="${cpool.minPoolSize}"/>
<property name="minPoolSize" value="${cpool.minPoolSize}" />
<property name="maxPoolSize" value="${cpool.maxPoolSize}" />
<property name="acquireIncrement" value="${cpool.acquireIncrement}" />
??? <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>??
</bean>

</beans>

這里只是配置了數據連接池,我使用c3p0 連接池,還沒有涉及到Quartx有關配置,下面且聽我慢慢道來。

四、實現動態定時任務
? 什么是動態定時任務:是由客戶制定生成的,服務端只知道該去執行什么任務,但任務的定時是不確定的(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服務啊,研究了下QuartzSpring中的動態定時,發現
引用
<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean" >
???????? <property name="jobDetail" ref="schedulerJobDetail"/>
???????? <property name="cronExpression">
???????????? <value>0/10 * * * * ?</value>
???????? </property>

cronExpression是關鍵,如果可以動態設置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,需要自己實現一個動態調度服務類,在其中構建CronTrigger或SimpleTrigger,動態配置時間。

    SchedulerService 只有一個多態方法schedule,SchedulerServiceImpl實現SchedulerService接口,注入org.quartz.Schedulert和org.quartz.JobDetail,schedule方法可以動態配置org.quartz.CronExpression或org.quartz.SimpleTrigger調度時間。

    五、實現自己的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

    Caused by: java.io.NotSerializableException: Unable to serialize JobDataMap for insertion into database because the value of property 'methodInvoker' is not serializable: org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

    ... 11 more


    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); ??
  • ????} ??
  • ??
  • }??
  • 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;}@Overrideprotected 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){ ??
  • ????????//這里執行定時調度業務 ??
  • ????????logger.info(triggerName); ??
  • ????} ??
  • ???? ??
  • ????public?void?testMethod2(){ ??
  • ????????logger.info("testMethod2"); ??
  • ????} ??
  • }??
  • 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){//這里執行定時調度業務logger.info(triggerName);}public void testMethod2(){logger.info("testMethod2");} }
    SimpleService主要執行定時調度業務,在這里我只是簡單打印一下log日志。SimpleService需要實現java.io.Serializable接口,否則會報

    quartzScheduler中沒有了
    引用
    <property name="triggers">
    <list>
    ... ?? ?
    </list>
    /property>

    配置,通過SchedulerService動態加入CronTrigger或SimpleTrigger。

    在紅色的
    引用

    <property name="jobDataAsMap">
    <map>
    <entry key="simpleService">
    <ref bean="simpleService" />
    </entry>
    </map>
    </property>


    中需要注入調度業務類,否則會報空指指錯誤。

    dataSource:項目中用到的數據源,里面包含了quartz用到的12張數據庫表;
    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行配置的,默認名稱是quartz.properties,里面配置的參數在quartz的doc文檔中都有介紹,可以調整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.driverDelegateClass=org.quartz.impl.jdbcjobstore.HSQLDBDelegate
    org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
    #org.quartz.jobStore.useProperties = true
    org.quartz.jobStore.tablePrefix = QRTZ_?
    org.quartz.jobStore.isClustered = false?
    org.quartz.jobStore.maxMisfiresToHandleAtATime=1

    這里面沒有數據源相關的配置部分,采用spring注入datasource的方式已經進行了配置。

    這樣只是簡單的將quartz trigger名稱打印出來。

    這樣通過SchedulerService就可以動態配置調度時間。其實SchedulerService 還可擴展,比如可以注入多個JobDetail,調度不同的JobDetail。
