一个QUATRZ很基本的例子(XML配置时间调度)

第一步:修改XML文件,内容如下:

<servlet>
<display-name>Quartz Initializer Servlet</display-name>
<servlet-name>QuartzInitializer</servlet-name>
<servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
<init-param>
<param-name>config-file</param-name>
<param-value>/quartz.properties</param-value> /*注意,这里是配置QUARTZ的基本参数*/
</init-param>
<init-param>
<param-name>shutdown-on-unload</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>

第二步:配置quartz.properties,将这个资源文件放到CLASSPATH下,内容如下:

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.LoggingTrigger
HistoryPlugin
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} complete
d firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger in
struction code: {9}

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializatio
nPlugin
org.quartz.plugin.jobInitializer.fileName = quartz_job.xml /*这个是配置任务调度的时间*/
org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHoo
kPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true

第三步:添加quartz_job.xml,将这个文件也放到CLASSPATH下,内容如下:

<?xml version="1.0" encoding="gb2312"?>
<quartz>
<job>
<job-detail>
<name>jobTest</name>
<group>group1</group>
<job-class>com.duiduihu.ecf.common.quartz.JobEcecute</job-class> /*任务调度类*/
</job-detail>
<trigger>
<cron>
<name>trigerTest</name>
<group>group1</group>
<job-name>jobTest</job-name>
<job-group>group1</job-group>

<!--每天晚上9点执行-->
<cron-expression>0 0 21 * * ?</cron-expression> /*这个是类似于LINUX的语法的cron-expression,具体在下面详细说明*/
</cron>
</trigger>
</job>
</quartz>

第四步 创建被调度任务类 内容如下:

package test.quartz;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.util.Date;

public class JobEcecute implements Job {
public void execute(JobExecutionContext context) throws
JobExecutionException {
System.out.println("任务调度成功! - " + new Date());
}
}
启动工程,进行测试.
