Quartz_2.2.X学习系列二十二：Example 10 - Using Quartz Plug-Ins

Demonstrates the use of the XML Job Initialization plug-in as well as the History Logging plug-ins

 

示例：

使用XML来设置Job和Trigger，不在代码中直接写，当执行sched.start();时会自动根据quartz.properties配置初始化，如果配置文件中有指定org.quartz.plugin.jobInitializer.fileNames，则会加载指定XML文件的Job与Trigger内容。

 

1.quartz.properties指定了org.quartz.plugin.jobInitializer的相关信息：

#============================================================================

# Configure Main Scheduler Properties 

#============================================================================

 

org.quartz.scheduler.instanceName: TestScheduler

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.PostgreSQLDelegate

#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: org.postgresql.Driver

#org.quartz.dataSource.myDS.URL: jdbc:postgresql://localhost/dev

#org.quartz.dataSource.myDS.user: jhouse

#org.quartz.dataSource.myDS.password:

#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

 

------------------------------------------------------------------------------------------------------------

 

2.XML中为该scheduler配置了：

TestJob1，关联org.quartz.examples.example10.SimpleJob这个Job类

与它关联的Trigger，TestSimpleTrigger1AtFiveSecondInterval，带misfire-instruction

 

TestJob2，关联org.quartz.examples.example10.SimpleJob这个Job类

a.TestSimpleTrigger2AtTenSecondIntervalAndFiveRepeats

b.TestCronTrigger2AtEveryMinute，带jobDataMap

c.TestCronTrigger2AtEveryMinuteOnThe45thSecond，带misfire-instruction
