我正在尝试使用 OSGi R6 注释创建一个 OSGi 服务，然后将其注入到 Sling Model 类中，如下所示：
package com.aem.sites.models;
import javax.annotation.PostConstruct;
import javax.inject.Inject;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.models.annotations.Model;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.aem.sites.services.WeatherService;
@Model(adaptables=Resource.class)
public class Banner {
final static Logger logger = LoggerFactory.getLogger(Banner.class);
@Inject
private WeatherService weatherService;
private String message;
@PostConstruct
public void init() {
logger.info("##############################################################calling the init method");
message = weatherService.getName();
}
public String getMessage() {
logger.info("##############################################################inside the get message method");
return message;
}
}
OSGi 配置界面如下所示：
package com.aem.sites.interfaces;
import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.AttributeType;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
@ObjectClassDefinition(name = "Configuration", description = "Configuration file")
public @interface Configuration {
@AttributeDefinition(
name = "String Property",
description = "Sample String property",
type = AttributeType.STRING
)
public String getText() default "It's a test";
}
服务类如下所示：
package com.aem.sites.services.impl;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Deactivate;
import org.osgi.service.component.annotations.Modified;
import org.osgi.service.component.annotations.ConfigurationPolicy;
import org.osgi.service.metatype.annotations.Designate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.aem.sites.interfaces.Configuration;
import com.aem.sites.services.WeatherService;
@Component(service=WeatherService.class,
immediate=true,
configurationPid = "com.aem.sites.services.impl.WeatherServiceImpl",
configurationPolicy=ConfigurationPolicy.REQUIRE
)
@Designate(ocd = Configuration.class)
public class WeatherServiceImpl implements WeatherService{
final static Logger logger =LoggerFactory.getLogger(WeatherServiceImpl.class);
private Configuration config;
private String name;
@Activate
@Modified
protected final void activate(Configuration configuration) {
logger.info("##############################################################calling activate method inside the weather service impl class");
this.config = configuration;
name = config.getText();
}
@Deactivate
protected void deactivate() {
}
@Override
public String getName() {
logger.info("##############################################################calling get name method inside the weather service impl class");
return name;
}
}
最后是服务接口：
package com.aem.sites.services;
public interface WeatherService {
public String getName();
}
我正在尝试在 HTL 类中使用 Sling Model Pojo，如下所示：
<sly data-sly-use.banner="com.aem.sites.models.Banner">
<div class="inner">
<h2>${banner.message}</h2
</div>
</sly>
但我看不到任何文字。我使用了 logger.info，但在日志文件中也看不到它。我确定我在这里做错了，但由于我刚刚开始使用 OSGi R6 注释和 Sling 模型，因此无法定位。任何帮助表示赞赏。
