AEM 6.3-使用OSGi R6注释创建事件处理程序

https://github.com/nateyolles/aem-osgi-annotation-demo/blob/master/core/src/main/java/com/nateyolles/aem/osgiannotationdemo/core/listeners/SampleOsgiResourceListener.java 而且效果很好。但是,我收到警告“添加的字段SlingConstants.TOPIC\u RESOURCE\u已弃用”。我搜索了一下,发现了这个帖子: https://forums.adobe.com/thread/2325819

以下是我面临的挑战:

1) 我想为我的事件处理程序创建一个单独的配置接口。我试过了,但没用

package com.aem.sites.interfaces;

import org.apache.sling.api.SlingConstants;
import org.osgi.service.event.EventConstants;
import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.AttributeType;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;

@ObjectClassDefinition(name = "Temperature Listener Configuration")
public @interface TemperatureListenerConfiguration {

    @AttributeDefinition(
            name = EventConstants.EVENT_FILTER,
            description = "Configurable paths for temperature event listener",
            type = AttributeType.STRING
            )
    String getPaths() default "/content/aemsite/en/jcr:content/root/responsivegrid/banner";

    @AttributeDefinition(
            name = EventConstants.EVENT_TOPIC,
            description = "Event types",
            type = AttributeType.STRING
            )
    String[] getEventTypes() default  {SlingConstants.TOPIC_RESOURCE_ADDED,SlingConstants.TOPIC_RESOURCE_CHANGED, SlingConstants.TOPIC_RESOURCE_REMOVED};

}

package com.aem.sites.listeners;

import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Modified;
import org.osgi.service.event.Event;
import org.osgi.service.event.EventHandler;
import org.osgi.service.metatype.annotations.Designate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.aem.sites.interfaces.TemperatureListenerConfiguration;

@Component(immediate=true,
service=EventHandler.class,
configurationPid = "com.aem.sites.listeners.EventHandler")
@Designate(ocd=TemperatureListenerConfiguration.class)
public class TemperaturePropertyListener implements EventHandler{

     private final Logger logger = LoggerFactory.getLogger(getClass());

    @Override
    public void handleEvent(Event event) {
        logger.info("*********************Event handler*****************************");

    }

    @Activate
    @Modified
    public void activate(TemperatureListenerConfiguration config) {
        //config.getPaths();
        logger.info("**************************TemperaturePropertyListener******************activate**********************");
    }

}

我还想要解决SlingConstants弃用的问题。不确定ResourceChangeListener是否是我问题的答案,如果是,那么代码中的一切将如何协同工作。

提前感谢

package com.aem.sites.listeners;

import java.util.List;

import org.apache.sling.api.resource.observation.ResourceChange;
import org.apache.sling.api.resource.observation.ResourceChangeListener;

@Component(immediate=true,
service=ResourceChangeListener.class,
configurationPid = "com.aem.sites.listeners.TemperaturePropertyListener")
@Designate(ocd=TemperatureListenerConfiguration.class)
public class TemperaturePropertyListener implements ResourceChangeListener{

     private final Logger logger = LoggerFactory.getLogger(getClass());

    @Override
    public void onChange(List<ResourceChange> changes) {
        for (final ResourceChange change : changes) {
            logger.info("**************************TemperaturePropertyListener******************change type**********************"+change.getType());
        }

    }


    @Activate
    @Modified
    public void activate(TemperatureListenerConfiguration config) {
        //config.getPaths();
        logger.info("**************************TemperaturePropertyListener******************activate**********************");
    }
}

            )
    String[] getPaths() default {"/content/aemsite/en/jcr:content/root/responsivegrid/banner"};

    @AttributeDefinition(
