quartz部署

 

最近因項目需要使用了quartz做任務調度，現將quartz部署過程記錄如下：

 

1.下載quartz包，解壓後，如下圖：

1）將quartz-2.1.7.jar包添加到項目中。

2）找到examples\example10目錄下的quartz.properties 、quartz_data.xml文件拷貝到項目源代碼根目錄下。

 

2.在web.xml中添加如下信息：

<!-- start -->
<context-param>
<param-name>quartz:config-file</param-name>
<param-value>quartz.properties</param-value>
</context-param>
<context-param>
<param-name>quartz:shutdown-on-unload</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:wait-on-shutdown</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:start-on-load</param-name>
<param-value>true</param-value>
</context-param>
<listener>
<listener-class>
org.quartz.ee.servlet.QuartzInitializerListener
</listener-class>
</listener>
<!-- end -->

 

3.修改quartz.properties文件：

#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName: LCGLScheduler
org.quartz.scheduler.instanceId: AUTO
org.quartz.scheduler.skipUpdateCheck: true
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 3
org.quartz.threadPool.threadPriority: 5
#============================================================================
# Configure JobStore
#============================================================================
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.oracle.OracleDelegate
#org.quartz.jobStore.useProperties: false
#org.quartz.jobStore.dataSource: myDS
#org.quartz.jobStore.tablePrefix: QRTZ_
#org.quartz.jobStore.isClustered: false
#============================================================================
# Configure Datasources
#============================================================================
org.quartz.dataSource.myDS.driver: oracle.jdbc.driver.OracleDriver
org.quartz.dataSource.myDS.URL: jdbc:oracle:thin:@10.28.19.120:1521:orcl
org.quartz.dataSource.myDS.user: lcgl
org.quartz.dataSource.myDS.password: lcgl
org.quartz.dataSource.myDS.maxConnections: 5
#============================================================================
# Configure Plugins
#============================================================================
org.quartz.plugin.triggHistory.class: org.quartz.plugins.history.LoggingJobHistoryPlugin
org.quartz.plugin.jobInitializer.class: org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames: quartz_data.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound: true
org.quartz.plugin.jobInitializer.scanInterval: 120
org.quartz.plugin.jobInitializer.wrapInUserTransaction: false

4.開發job類。可參考上述下載包中的例子，本處使用的是Contrigger 類型的trigger。

5.在quartz_data.xml中配置調度信息：

<?xml version="1.0" encoding="UTF-8"?>
<job-scheduling-data xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_2_0.xsd"
version="2.0">
<pre-processing-commands>
<delete-jobs-in-group>*</delete-jobs-in-group>  <!-- clear all jobs in scheduler -->
<delete-triggers-in-group>*</delete-triggers-in-group> <!-- clear all triggers in scheduler -->
</pre-processing-commands>
<processing-directives>
<!-- if there are any jobs/trigger in scheduler of same name (as in this file), overwrite them -->
<overwrite-existing-data>true</overwrite-existing-data>
<!-- if there are any jobs/trigger in scheduler of same name (as in this file), and over-write is false, ignore them rather then generating an error -->
<ignore-duplicates>false</ignore-duplicates>
</processing-directives>
<schedule>
<job>
<name>SMSWarnJob1</name>
<group>Job-Group1</group>
<job-class>com.xx.xx.xx.job.xxxxJob</job-class>
</job>
<trigger>
<cron>
<name>SMSWarnCronTrigger1</name>
<group>Trigger-Group1</group>
<job-name>SMSWarnJob1</job-name>
<job-group>Job-Group1</job-group>
<!-- start-time>2010-02-09T12:26:00.0</start-time -->
<!--end-time>2012-02-09T12:26:00.0</end-time-->
<misfire-instruction>MISFIRE_INSTRUCTION_DO_NOTHING</misfire-instruction>
<cron-expression>0 16 11 ? * *</cron-expression>
<!--time-zone>America/Los_Angeles</time-zone -->
</cron>
</trigger>
<trigger>
<cron>
<name>SMSWarnCronTrigger2</name>
<group>Trigger-Group1</group>
<job-name>SMSWarnJob1</job-name>
<job-group>Job-Group1</job-group>
<!-- start-time>2010-02-09T12:26:00.0</start-time -->
<!--end-time>2012-02-09T12:26:00.0</end-time-->
<misfire-instruction>MISFIRE_INSTRUCTION_DO_NOTHING</misfire-instruction>
<cron-expression>0 15 11 ? * *</cron-expression>
<!--time-zone>America/Los_Angeles</time-zone -->
</cron>
</trigger>
</schedule>
</job-scheduling-data>

6.啓動tomcat服務器測試任務。
