Quartz 在 Spring 中如何动态配置时间
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(xiàn)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(diào)度任務時間,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(diào)度任務會在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。但是這是quartz使用“內(nèi)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(diào)度任務的狀態(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(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
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
??? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

?
?? <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(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="${jdbc.driverClassName}" />
<property name="jdbcUrl" value="${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(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
? 什么是動態(tài)定時任務:是由客戶制定生成的,服務端只知道該去執(zhí)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); ?? ????} ?? ?? }?? package com.sundoctor.example.service;import org.quartz.JobExecutionContext;

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

}
SimpleService主要執(zhí)行定時調(diào)度業(yè)務,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

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(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

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(tài)配置調(diào)度時間。其實SchedulerService 還可擴展,比如可以注入多個JobDetail,調(diào)度不同的JobDetail。
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(diào)度任務會在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。但是這是quartz使用“內(nèi)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(diào)度任務的狀態(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(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
<?xml version="1.0" encoding="UTF-8"?>

</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="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
? 什么是動態(tài)定時任務:是由客戶制定生成的,服務端只知道該去執(zhí)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)度服務類,在其中構(gòu)建CronTrigger或SimpleTrigger,動態(tài)配置時間。
動態(tài)調(diào)度服務接口:
Java代碼
動態(tài)調(diào)度服務實現(xiàn)類:
Java代碼
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
MyQuartzJobBean繼承org.springframework.scheduling.quartz.QuartzJobBean,注入的SimpleService如下:
Java代碼
SimpleService主要執(zhí)行定時調(diào)度業(yè)務,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

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)進行了配置。
