quartz 执行定时任务配置及案例
准备工作
导入jar包：\WEB-INF\lib\quartz-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" xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd" version="1.8"> <schedule> <job> <name> ws_soap_job</name> <group>ErrLog</group> <description>The job description </description> <job-class>com.gmw9.quartz.WsSoapQuartzJob</job-class> </job> <trigger> <cron> <name>wsSoap-trigger</name> <group>ErrLog_GROUP</group> <job-name>ws_soap_job</job-name> <job-group>ErrLog</job-group> <cron-expression>0 0 8,12,16,20 * * ?</cron-expression> </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> <job-name>jabName</job-name> <job-group>upload</job-group> <cron-expression>0 10 15 22 4 ? 2016</cron-expression> </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======="); } }
