[Spring] Quartz 스케줄러 연동 퀵가이드~ :)

그냥 기록차원에서 잽싸게 끄적거려 봄~!! ^^

0. 만약 maven을 사용한다면 pom.xml에 아래 내용 추가.

(버전은 최신버전을 사용하면 됨)

<!--  program scheduler -->

        <dependency>

        <groupId>org.quartz-scheduler</groupId>

            <artifactId>quartz</artifactId>

            <version>1.8.5</version>

        </dependency>

1. 우선, web.xml에 아래 내용 추가.

(jobContext.xml에 스케줄러 관련 내용이 있음)

<servlet>

<servlet-name>appServlet</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>

/WEB-INF/spring/appServlet/servlet-context.xml

   /WEB-INF/spring/jobContext.xml

</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

2. jobContext.xml 은 내용~

설정 순서는,

i)스케줄러의 타입을 먼저 설정(메소드 타입인지 다른(?) 타입인지)

ii)스케줄러 구현체(클래스) 설정

iii)스케줄러 트리거(실행조건) 설정(일반설정과 crontab 스타일 설정이 있음)

       <list>

           <ref bean="trgSelectRequestedBookingProductJob" />

       </list>

   </property>

</bean>

</beans>

3. 실제 스케줄러 구현 클래스~

public class SelectRequestedBookingProductJob {

public void selectBookingCondition(boolean bRunJob, int serverTotalCount, int nowServerId) {

if( bRunJob ) {

try {

System.out.println("\n\n==== Run Job. Hello Job~ :) serverTotalCount["+ serverTotalCount +"] nowServerId["+ nowServerId +"] ====\n\n");

}catch(Exception e) {

e.printStackTrace();

}

}else {

System.out.println("\n\n==== Do not Run Job. ====\n\n");

}

}

}

4. WAS 재구동하면 정해진 트리거 조건에 따라 

SelectRequestedBookingProductJob.selectBookingCondition 메소드 실행~!! :)
