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_Joborg.quartz.scheduler.instanceId = AUTO#============================================================================# Configure ThreadPool #============================================================================org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPoolorg.quartz.threadPool.threadCount = 10org.quartz.threadPool.threadPriority = 1#============================================================================# Configure JobStore #============================================================================org.quartz.jobStore.misfireThreshold = 60000org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTXorg.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.oracle.OracleDelegateorg.quartz.jobStore.useProperties = falseorg.quartz.jobStore.dataSource = dbJobDSorg.quartz.jobStore.tablePrefix = QRTZ_org.quartz.jobStore.isClustered = trueorg.quartz.jobStore.clusterCheckinInterval = 20000#============================================================================# Configure Datasources #============================================================================org.quartz.dataSource.dbJobDS.jndiURL=jdbc/jdbcname#============================================================================# Configure Plugins #============================================================================org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPluginorg.quartz.plugin.jobInitializer.fileNames = db_jobs.xmlorg.quartz.plugin.jobInitializer.failOnFileNotFound = trueorg.quartz.plugin.jobInitializer.scanInterval = 10000org.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>?
