1. SpringDMd을 사용
1-1. 이벤트 핸들러로 이벤트 받기
Manifest.mf의 Import-Package에 org.osgi.service.event 추가
1-1-1. 인터페이스
public interface EventHandler {
void handleEvnet(Event event);
}
1-1-2. 구현체
public class 클래스명 implements EventHandler {
//인터페이스 구현체
public void handleEvent(Event event) {
System.out.println("\r\n[Event Received] Topic : " + event.getTopic());
for(String key : event.getPropertyNames()){
System.out.println("\t[Property] " + key + " : " + event.getProperty(key));
}
}
}
1-1-3. spring.xml
<osgi:service id="EventAdminServiceBean명" ref="구현EventAdminBean명" interface="org.osgi.service.event.EventHandler">
<osgi:service-properties>
<entry key="event.topics" value="Topic주소" />
</osgi:service-properties>
</osgi:service>
<bean id="구현EventAdminBean명" class="구현EventAdmin경로" />
1-2. 이벤트 보내기
1-2-1. 구현체
public class 클래스명 {
private EventAdmin eventAdmin;
@ServiceReference
public void setEventAdmin(EventAdmin eventAdmin) {
this.eventAdmin = eventAdmin;
}
private String EVENT_QUEUE;
public void setEVENT_QUEUE(String EVENT_QUEUE) {
this.EVENT_QUEUE = EVENT_QUEUE;
}
public void sender(){
Properties props = new Properties();
props.put("key", "value");
//동기 전송: sendEvent, 비동기 전송: postEvent
eventAdmin.sendEvent(new Event(EVENT_QUEUE, props));
}
}
1-2-2. spring.xml
<bean id="클래스Bean명" class="클래스 경로" init-method="실행 메서드 명">
<property name="EVENT_QUEUE" value="Topic주소" />
</bean>
<bean class="org.springframework.osgi.extensions.annotation.ServiceReferenceInjectionBeanPostProcessor" />
1-2-3. event를 보내기 위해 spring-osgi-annotation jar파일 필요
Maven을 사용한다면 dependency를 추가 하거나 아니며 spring-osgi-annotation jar파일이 필요
<dependency>
<groupId>org.springframework.osgi</groupId>
<artifactId>org.springframework.osgi.extensions.annotation</artifactId>
<version>1.2.1</version>
</dependency>
