第一篇中增加的是程序代码的实现,本篇我们将通过配置文件进行定时器的配置,减少代码量,提高灵活性。

1、需要用到的文件:quartz.properties,据说这个文件如果没有的话,按默认的走,结果布署到tomcat中,提示找不到该文件;

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

# Configure Main Scheduler Properties  

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

org.quartz.scheduler.instanceName = QuartzScheduler

org.quartz.scheduler.instanceId = AUTO

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

# Configure ThreadPool  

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

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

org.quartz.threadPool.threadCount =2

org.quartz.threadPool.threadPriority = 5

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

# Configure JobStore  

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

org.quartz.jobStore.misfireThreshold = 60000

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

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

# Configure Plugins 

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

org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin

org.quartz.plugin.jobInitializer.fileNames = jobs.xml

org.quartz.plugin.jobInitializer.overWriteExistingJobs = true

org.quartz.plugin.jobInitializer.failOnFileNotFound = true

org.quartz.plugin.jobInitializer.scanInterval = 10

org.quartz.plugin.jobInitializer.wrapInUserTransaction = false

 2、jobs.xml ,上文提到的配置文件,配置触发器和job名称等;

<?xml version=‘1.0‘ encoding=‘utf-8‘?>
<quartz xmlns="http://www.opensymphony.com/quartz/JobSchedulingData"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.opensymphony.com/quartz/JobSchedulingData
  http://www.opensymphony.com/quartz/xml/job_scheduling_data_1_5.xsd"
  version="1.5">   
 <job>      
    <job-detail>      
     <name>HelloWorld</name>      
     <group>DEFAULT</group>      
     <description>      
           A job that just for test       
     </description>      
     <job-class>      
            cn.jfinal.job.RedPacketValidate      
     </job-class>      
     <volatility>false</volatility>      
     <durability>false</durability>      
     <recover>false</recover>          
  </job-detail>      
  <trigger>      
    <simple>      
     <name>HelloTrigger1</name>      
     <group>DEFAULT</group>      
     <job-name>RedPacketValidate</job-name>      
     <job-group>DEFAULT</job-group>      
     <start-time>2015-10-26T16:56:30</start-time>      
     <!-- repeat indefinitely every 10 seconds -->      
     <repeat-count>-1</repeat-count>      
     <repeat-interval>10000</repeat-interval>      
    </simple>      
  </trigger>      
</job>      
</quartz>

上面这两个文件要放在apache-tomcat-7.0.59\webapps\jfinal_demo\WEB-INF\classes 中,才能有效。

3、一些必须的jar包要添加到lib中:

 

     创建一个Web项目,将quartz-1.6.0.jar,以及lib目录下面core下所有jar,optional目录下的所有commons-beanutils.jar和commons-digester-1.7.jar,build目录下的jta.jar都放入Web项目的WEB-INF"lib目录下。

jta.jar说明:java JTA规范;

 

4、web.xml 配置

 <servlet>  
        <servlet-name>QuartzInitializer</servlet-name>  
        <display-name>Quartz Initializer Servlet</display-name>
        <servlet-class>  
             org.quartz.ee.servlet.QuartzInitializerServlet  
        </servlet-class>  
        <load-on-startup>1</load-on-startup>  
        <init-param>  
            <param-name>config-file</param-name>  
            <param-value>/quartz.properties</param-value>  
        </init-param>  
        <init-param>  
            <param-name>shutdown-on-unload</param-name>  
            <param-value>true</param-value>  
       </init-param>  
    </servlet>
