tomcat和quartz集成配置

quartz任务可以随tomcat启动而启动调度，不需要手动启动调度进程。
1.修改web.xml     <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> 2.在webapps/axis/WEB-INF/classes目录下建立文件quartz.properties org.quartz.scheduler.instanceName = TestScheduler
org.quartz.scheduler.instanceId = one org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 2
org.quartz.threadPool.threadPriority = 4 org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingTriggerHistoryPlugin
org.quartz.plugin.triggHistory.triggerFiredMessage = Trigger {1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}
org.quartz.plugin.triggHistory.triggerCompleteMessage = Trigger {1}.{0} completed firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9} org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = quartz_job.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true 3.在同目录建立文件 quartz_job.xml <?xml version="1.0" encoding="UTF-8"?>
<quartz>
<job>
    <job-detail>
      <name>helloworld</name>
      <group>group1</group>
      <job-class>HelloWorld</job-class>
    </job-detail>
    <trigger>
      <cron>
        <name>test</name>
        <group>group1</group>
        <job-name>helloworld</job-name>
        <job-group>group1</job-group>
        <cron-expression>0 0/1 * * * ?</cron-expression>
     </cron>
    </trigger>
</job>
</quartz>
4.在同目录下增加java文件并编译：
   

import java.util.Date;  

  

import org.apache.commons.logging.Log;  

import org.apache.commons.logging.LogFactory;  

import org.quartz.Job;  

import org.quartz.JobExecutionContext;  

import org.quartz.JobExecutionException;  

  

public class Helloworld implements Job{  

public Helloworld() {  

}  

  

private static Log _log = LogFactory  

    .getLog(Helloworld.class);  

  

public void execute(JobExecutionContext context)  

   throws JobExecutionException {  

   _log.info("Hello World! - " + new Date());  

}  

}

注意log4j版本要求较新，否则可能报错：
Java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled
