Quartz任务监控治理
Quartz任务监控管理,类似Windows任务管理器,可以获得运行时的实时监控,查看任务运行状态,动态增加任务,暂停、恢复、移除任务等。对于动
态增加任务,可以参加我的前一篇文章《Quartz如何在Spring动态配置时间》,本文在前文的基础上扩展,增加暂停、恢复、移除任务等功能,实现
Quartz任务监控管理。
先看一下最终实现实现效果,只有两个页面 ,如下
在这个页面查看任务实时运行状态,可以暂停、恢复、移除任务等
在这个页面可以动态配置调度任务。
实现任务监控,必须能将数据持久化,这里采用数据库方式,Quartz对任务的数据库持久化有着非常好的支持。我在这里采用quartz
1.6.5,在Quartz发行包的docs\dbTables目录包含有各种数据库对应脚本,我用的是MySql
5.0,所以选用tables_mysql_innodb.sql建表。
建表完成后,配置数据库连接池,分两步:
1、配置jdbc.properties文件
- 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
- 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
2.配置applicationContext.xml文件
- <bean id= "propertyConfigurer" class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
- <property name= "locations" >
- <list>
- <value>classpath:jdbc.properties</value>
- </list>
- </property>
- </bean>
- <!-- 数据源定义,使用c3p0 连接池 -->
- <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= "${cpool.maxIdleTime}" />
- </bean>
- <bean id= "propertyConfigurer" class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
- <property name="locations" >
- <list>
- <value>classpath:jdbc.properties</value>
- </list>
- </property>
- </bean>
- <!-- 数据源定义,使用c3p0 连接池 -->
- <bean id="dataSource" class = "com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method= "close" >
- <property name="driverClass" value= "${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>
配置Quartz,也分两步
1、配置quartz. properties
- …
- 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.StdJDBCDelegate
- #org.quartz.jobStore.useProperties = true
- org.quartz.jobStore.tablePrefix = QRTZ_
- org.quartz.jobStore.isClustered = false org.quartz.jobStore.maxMisfiresToHandleAtATime= 1
- …
- 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.StdJDBCDelegate
- #org.quartz.jobStore.useProperties = true
- org.quartz.jobStore.tablePrefix = QRTZ_
- org.quartz.jobStore.isClustered = false org.quartz.jobStore.maxMisfiresToHandleAtATime= 1
在这里采用JobStoreTX,将任务持久化到数据中,而不再是简单的内存方式:RAMJobStore
2、配置applicationContext-quartz.xml
- <bean name= "quartzScheduler" class = "org.springframework.scheduling.quartz.SchedulerFactoryBean" >
- <property name= "dataSource" ref = "dataSource" />
- <property name= "applicationContextSchedulerContextKey" value= "applicationContextKey" />
- <property name= "configLocation" value= "classpath:quartz.properties" />
- </bean>
- <bean id= "jobDetail" class = "org.springframework.scheduling.quartz.JobDetailBean" >
- <property name= "jobClass" >
- <value>
- com.sundoctor.example.service.MyQuartzJobBean
- </value>
- </property>
- <property name= "jobDataAsMap" >
- <map>
- <entry key= "simpleService" >
- <ref bean= "simpleService" />
- </entry>
- </map>
- </property>
- </bean>
- <bean name= "quartzScheduler" class = "org.springframework.scheduling.quartz.SchedulerFactoryBean" >
- <property name="dataSource" ref = "dataSource" />
- <property name="applicationContextSchedulerContextKey" value= "applicationContextKey" />
- <property name="configLocation" value= "classpath:quartz.properties" />
- </bean>
- <bean id="jobDetail" class = "org.springframework.scheduling.quartz.JobDetailBean" >
- <property name="jobClass" >
- <value>
- com.sundoctor.example.service.MyQuartzJobBean
- </value>
- </property>
- <property name="jobDataAsMap" >
- <map>
- <entry key="simpleService" >
- <ref bean="simpleService" />
- </entry>
- </map>
- </property>
- </bean>
到些,相关配置全部完成,对于配置的具体描述,可以参加我的前一篇文章《Quartz如何在Spring动态配置时间》
实现任务动态添加配置
请参考com.sundoctor.quartz.service.SchedulerServiceImpl.java中的各种schedule方法,在《Quartz如何在Spring动态配置时间》有具体描述。在这里说一下:
添加一个Job在表qrtz_job_details插入一条记录
添加一个Simple Trigger在表qrtz_simple_triggers插入一条记录
添加一个Cron Trigger 在表qrtz_cron_triggers插入一条记录
添加Simple Trigger和Cron Trigger都会同进在表qrtz_triggers插入一条记录,开始看的第一个页面调度任务列表数据就是从qrtz_triggers表获取
实现任务实时监控,暂停、恢复、移除任务等
在com.sundoctor.quartz.service.SchedulerServiceImpl.java类中
暂停任务
- public void pauseTrigger(String triggerName,String group){
- try {
- scheduler.pauseTrigger(triggerName, group); //停止触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
- public void pauseTrigger(String triggerName,String group){
- try {
- scheduler.pauseTrigger(triggerName, group);//停止触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
恢复任务
- public void resumeTrigger(String triggerName,String group){
- try {
- scheduler.resumeTrigger(triggerName, group); //重启触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
- public void resumeTrigger(String triggerName,String group){
- try {
- scheduler.resumeTrigger(triggerName, group);//重启触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
移除任务
- public boolean removeTrigdger(String triggerName,String group){
- try {
- scheduler.pauseTrigger(triggerName, group); //停止触发器
- return scheduler.unscheduleJob(triggerName, group); //移除触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
- public boolean removeTrigdger(String triggerName,String group){
- try {
- scheduler.pauseTrigger(triggerName, group);//停止触发器
- return scheduler.unscheduleJob(triggerName, group); //移除触发器
- } catch (SchedulerException e) {
- throw new RuntimeException(e);
- }
- }
其它类的实现请参加《Quartz如何在Spring动态配置时间》,那里有具体说明。
到此,基本简单实现了Quartz任务监控管理。其实面这里只是实现了Trigger任务的监控管理,没有实现Job任务的监控管理,实现Job任务的监
控管理跟Trigger差不多。用Quartz可以很方便实现多样化的任务监控管理,Trigger任务和Job任务都可进行分组管理。
Quartz很强大,也很简单,只有想不到的,没有做不到的,人有多大胆,地有多高产。
