Quartz 스케줄러

주기적으로 실행해야 할 작업이 있을경우 사용하는 스케줄러

1. quartz 다운로드 : http://www.quartz-scheduler.org/download/
    다운받은후 WEB-INF/lib 에 다운받은 quartz-1.7.jar을 추가한다.

2. WEB-INF/web.xml 에 quartz 자동으로 실행할수 있도록 추가

<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>com/ineast/scheduler/quartz.properties</param-value>         </init-param>         <init-param>             <param-name>shutdown-on-unload</param-name>             <param-value>true</param-value>         </init-param>         <init-param>             <param-name>start-scheduler-on-load</param-name>             <param-value>true</param-value>         </init-param>         <load-on-startup>1</load-on-startup>    </servlet>    <servlet>         <display-name>SchedulerInit</display-name>         <servlet-name>SchedulerInit</servlet-name>         <servlet-class>com.ineast.scheduler.SchedulerInit</servlet-class>         <load-on-startup>2</load-on-startup>    </servlet>    <servlet-mapping>         <servlet-name>SchedulerInit</servlet-name>         <url-pattern>/SchedulerInit</url-pattern>    </servlet-mapping>

3. quartz.properties 생성

org.quartz.scheduler.instanceName = SchedulerInit    org.quartz.scheduler.instanceId = AUTO    org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool    org.quartz.threadPool.threadCount = 12    org.quartz.threadPool.threadPriority = 5    org.quartz.jobStore.misfireThreshold = 60000    org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore  org.quartz.scheduler.instanceName = SchedulerInit org.quartz.scheduler.instanceId = AUTO org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount = 12 org.quartz.threadPool.threadPriority = 5 org.quartz.jobStore.misfireThreshold = 60000 org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

4. SchedulerInit.java 생성

package com.ineast.scheduler;     import java.text.ParseException;    import org.quartz.CronTrigger;    import org.quartz.JobDetail;    import org.quartz.Scheduler;    import org.quartz.SchedulerException;    import org.quartz.SchedulerFactory;    import org.quartz.impl.StdSchedulerFactory;       public class SchedulerInit {         private SchedulerFactory schedFact;         private Scheduler sched;         public SchedulerInit() {             try {                 schedFact = new StdSchedulerFactory();                 sched = schedFact.getScheduler();                 sched.start();                 JobDetail job1 = new JobDetail("Schedule", "group1", Schedule.class);                  CronTrigger trigger1 = new CronTrigger("Trigger_Schedule", "group1", "0/30 * * * * ?");                  sched.scheduleJob(job1, trigger1);             } catch (SchedulerException e) {                 e.printStackTrace();             } catch (ParseException e) {                 e.printStackTrace();             }         }         public static void main(String[] args) {             new SchedulerInit();         }    }

5. Schedule.java 생성

package com.ineast.scheduler;    import org.quartz.Job;    import org.quartz.JobExecutionContext;    import org.quartz.JobExecutionException;       public class Schedule implements Job {           public void execute(JobExecutionContext context) throws JobExecutionException {             getMyAlarmData();      }         public void getMyAlarmData() {            System.out.println("스케줄러 실행중");      }     }
