2. Quartz Scheduler 사용방법

1) pom.xml : 라이브러리 추가

<!-- Quartz Scheduler -->
<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>2.3.2</version>
</dependency>

<dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz-jobs</artifactId>
    <version>2.3.2</version>
</dependency>

<!-- Quartz 지원 Spring 라이브러리 -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>${org.springframework-version}</version>
</dependency>

2. Service 어노테이션 추가

스케쥴러를 적용하려는 클래스에 어노테이션 추가

package com.crizen.task;

import java.util.List;

import org.springframework.stereotype.Service;

import com.crizen.domain.Counsel;
import com.crizen.domain.Reply;
import com.crizen.mapper.BoardMapper;
import com.crizen.mapper.ReplyMapper;

import lombok.AllArgsConstructor;
import lombok.extern.log4j.Log4j;

@Log4j
@Service("quartz") // Service 어노테이션 추가
@AllArgsConstructor
public class QuartzServiceImpl implements QuartzService {
	
	private BoardMapper boardMapper;
	private ReplyMapper replyMapper;
	
	@Override
	public void removeOvertime() {
		List<Counsel> removeList = boardMapper.findRemoveList();
		
		for(Counsel c : removeList) {
			replyMapper.deleteAll(c.getCounsel_bno());
			boardMapper.delete(c.getCounsel_bno());
		}
		
		log.warn("==== 게 시 글 삭 제 ====");
		log.warn("게시글 : " + removeList.size() + " 개 삭제 완료");
		log.warn("========================");
	}
	
	@Override
	public void modifySlang() {
		List<Counsel> boardSlangs = boardMapper.findSlangList();
		List<Reply> replySlangs = replyMapper.findSlangList();
		
		for(Counsel c : boardSlangs) {
			boardMapper.changeSlang(c);
		}
		
		for(Reply r : replySlangs) {
			replyMapper.update(r);
		}
		
		log.warn("==== 비 속 어 검 열 ====");
		log.warn("게시글 : " + boardSlangs.size() + " 개 변경 완료");
		log.warn("덧  글 : " + replySlangs.size() + " 개 변경 완료");
		log.warn("========================");
	}
}

3. root-context.xml 세팅 (≒scheduler-context.xml)

root-context.xml 세팅

<!-- Spring Quartz -->
<!-- Job -->
<bean id="removeOvertimeQuartz" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="quartz" />
    <property name="targetMethod" value="removeOvertime" />
    <property name="concurrent" value="false" />
</bean>

<!-- Trigger -->
<bean id="removeOvertimeTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail" ref="removeOvertimeQuartz" />
    <property name="cronExpression" value="0 0 8 * * ?" />
</bean>

<!-- Job -->
<bean id="modifySlangQuartz" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="quartz" />
    <property name="targetMethod" value="modifySlang" />
    <property name="concurrent" value="false" />
</bean>

<!-- Trigger -->
<bean id="modifySlangTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail" ref="modifySlangQuartz" />
    <property name="cronExpression" value="0 0/3 * * * ?" />
</bean>

<!-- Scheduler -->
<bean id="boardScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="removeOvertimeTrigger" />
            <ref bean="modifySlangTrigger" />
        </list>
    </property>
</bean>
