quartz 执行定时任务配置及案例

准备工作
导入jar包：WEB-INFlibquartz-1.8.5.jar

web.xml中的配置如下

<!-- quartz job start -->
    <context-param>
        <param-name>quartz:wait-on-shutdown</param-name>
        <param-value>true</param-value>
    </context-param>
    <servlet>     
        <servlet-name>QuartzInitializer</servlet-name>     
        <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>     
        <init-param>     
            <param-name>config-file</param-name> 
            <param-value>config/quartz_jobs.properties</param-value>     
        </init-param>     
        <init-param>     
            <param-name>shutdown-on-unload</param-name>     
            <param-value>true</param-value>     
        </init-param>    
        <init-param>     
            <!-- Start delay time 60 seconds -->
            <param-name>start-delay-seconds</param-name>     
            <param-value>60</param-value>     
        </init-param>
        <init-param>     
            <param-name>start-scheduler-on-load</param-name>     
            <param-value>true</param-value>     
        </init-param>   
        <load-on-startup>     
             5    
        </load-on-startup>     
       </servlet>
<!-- quartz job end -->

web.xml中配置的config/quartz_jobs.properties文件内的详细内容如下

quartz_jobs.properties文件内的/WEB-INF/quartzjobs.xml 详细配置 主要是指定去定时执行那个类 请看配置如下

<?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"

            <group>ErrLog</group>
            <description>The job description </description>
            <job-class>com.gmw9.quartz.WsSoapQuartzJob</job-class>
        </job>
        <trigger>

            </cron> 
        </trigger>       
        
        <!-- 
         <job>
            <name>jabName</name>
            <group>upload</group>
            <description>The job description </description>
            <job-class>com.gmw9.quartz.hongshanQuartzJob</job-class>
        </job>
        <trigger>
            <cron>
                <name>uploadFile-trigger</name>
                <group>upload_GROUP</group>

            </cron> 
        </trigger> -->
        
    </schedule> 
</job-scheduling-data>

被执行类的案例代码如下

package com.gmw9.quartz;

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 WsSoapQuartzJob implements Job {

    private final String JOBNAME = Constant.JOBNAME;
    private final static Log log = LogFactory.getLog(WsSoapQuartzJob.class);

    //定时任务框架会调用这个方法
    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        System.out.println("IVS wsSoap quartz job launch time ..."
                + System.currentTimeMillis());
        
            this.wsSoapCall();
        
    }
    //这里就是定时执行的内容
    public void wsSoapCall(){
        System.out.println("========wsSoap Call=======");
    }

}
