java - 坩埚 : No listener invokers were found for listener

Question

我正在尝试捕捉评论状态事件，例如有人正在关闭它。并在从插件中获得任何生命迹象之后。向日志文件(从任何日志级别)或 STDOUT 发送一行。atlassian-plugins.xml 看起来像这样:

 <component-import key="eventPublisher" interface="com.atlassian.event.api.EventPublisher"/>

<component key="reviewListenerNew" class="com.harman.ListenerNew.ReviewListenerNew">
    <description>Class that processes the incoming Review events.</description>
</component>

类本身在这里:

package com.harman.ListenerNew;
import com.atlassian.crucible.event.ReviewStateChangedEvent;
import com.atlassian.crucible.spi.data.ReviewData;
import com.atlassian.crucible.spi.services.ReviewService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;

public class ReviewListenerNew implements InitializingBean, DisposableBean{
private final EventPublisher eventPublisher;
private final ReviewService reviewService;
private final ReviewManager reviewManager;
private final UserManager userManager;

private final Logger log = Logger.getLogger(ReviewListenerNew.class);

public ReviewListenerNew(EventPublisher eventPublisher, ReviewService reviewService, ReviewManager reviewManager, UserManager userManager){
    this.eventPublisher = eventPublisher;
    this.reviewService = reviewService;
    this.reviewManager = reviewManager;
    this.userManager = userManager;

}
public Class[] getHandledEventClasses() {
    return new Class[0];
}


public void handEvent(ReviewStateChangedEvent event) {
    if (event.getNewState().equals(ReviewData.State.Closed))
    {
        log.warn("Event occured" + event);
        log.info("Event occured" + event);
        log.info("Event occured" + event.getNewState());
        log.error("Event occured" + event);
        log.debug("Event occured" + event);
        System.out.println("Event: " + event);

    }
        return;

}

@Override
public void destroy() throws Exception {

    eventPublisher.unregister(this);
}

@Override
public void afterPropertiesSet() throws Exception {
    eventPublisher.register(this);
}
}

这可以成功构建和上传，但无法启动。错误信息是:

还有另一个类的尝试:

package com.harman.ListenerNew;

import com.atlassian.crucible.event.ReviewStateChangedEvent;
import com.atlassian.crucible.spi.data.ReviewData;
import com.atlassian.crucible.spi.services.ReviewService;
import com.atlassian.event.api.EventPublisher;
import com.cenqua.crucible.model.Review;
import com.cenqua.crucible.model.managers.ReviewManager;
import com.cenqua.fisheye.user.UserManager;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.InitializingBean;
import com.atlassian.event.api.EventListener;

public class ReviewListenerNew{
private final Logger log = Logger.getLogger(ReviewListenerNew.class);

public Class[] getHandledEventClasses() {
    return new Class[0];
}

@EventListener
public void handleEvent(ReviewStateChangedEvent event) {
    if (event.getNewState().equals(ReviewData.State.Closed))
    {
        log.warn("Event occured" + event);
        log.info("Event occured" + event);
        log.info("Event occured" + event.getNewState());
        log.error("Event occured" + event);
        log.debug("Event occured" + event);
        System.out.println("Event: " + event);

    }
        return;

}

}

但在这种情况下，这可以构建和上传，看起来甚至已经开始，但没有任何 Action 。

Answer 1

似乎关键组件必须是 eventListener:

 <component key="eventListener" class="com.harman.NewEventListener">
    <description>Class that processes the new Crucible event</description>
</component>
