Quartz job 整理

1. 可以用web.xml初始化SchedulerFactory。

<servlet>
        <servlet-name>QuartzDBJobInitializer</servlet-name>
        <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
        <init-param>
            <param-name>servlet-context-factory-key</param-name>
            <param-value>DBJobSchedulerFactory</param-value>
        </init-param>
        <init-param>
            <param-name>start-scheduler-on-load</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>shutdown-on-unload</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>config-file</param-name>
            <param-value>/db_jobs.properties</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

 

2.配置propertied.

#============================================================================
# Configure Main Scheduler Properties  
#============================================================================
org.quartz.scheduler.instanceName = DB_Job
org.quartz.scheduler.instanceId = AUTO

#============================================================================
# Configure ThreadPool  
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 10
org.quartz.threadPool.threadPriority = 1

#============================================================================
# Configure JobStore  
#============================================================================
org.quartz.jobStore.misfireThreshold = 60000
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 = dbJobDS
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 20000

#============================================================================
# Configure Datasources  
#============================================================================
org.quartz.dataSource.dbJobDS.jndiURL=jdbc/jdbcname

#============================================================================
# Configure Plugins 
#============================================================================
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = db_jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 10000
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false

 3.配置schedule的job和Trigger。

<?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_1_8.xsd"
    version="1.8">
    <pre-processing-commands>   
        <!-- clean up useless job and trigger -->
        <delete-jobs-in-group>DEFAULT</delete-jobs-in-group>
        <delete-triggers-in-group>DEFAULT</delete-triggers-in-group>        
    </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>job_name</name>
            <group>DEFAULT</group>
            <job-class>job_class</job-class>
        </job>
        <trigger>
            <cron>
                <name>trigger_name</name>
                <group>DEFAULT</group>
                <job-name>job_name</job-name>
                <job-group>job_class</job-group>
                <cron-expression>0 0 1 * * ?</cron-expression>
            </cron>
        </trigger>        
    </schedule>
</job-scheduling-data>
