Creating and Reading OSGi Configuration Values for Adobe Experience Manager 6.3

Step 1: Create an Interface names MyServiceConfiguration and give the appropriate properties as mentioned below:

package com.demo.config.core;

import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.AttributeType;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;

@ObjectClassDefinition(name = "My Service Configuration", description = "Service Configuration")
public @interface MyServiceConfiguration {

@AttributeDefinition(name = "Config Value", description = "Configuration value")
String configValue();

@AttributeDefinition(name = "MultipleValues", description = "Multi Configuration values")
String[] getStringValues();

@AttributeDefinition(name = "NumberValue", description = "Number values", type=AttributeType.INTEGER)
int getNumberValue();

}

Step 2: Now create MySimpleService interface which will be used by the service:

package com.demo.config.core;

public interface MySimpleService {

String getSimpleValue();
boolean isAuthor();

}

Step 3: Now create MySimpleServiceImpl service which will read the configurations values:

@Component – defines the class as a component
@Designate – defines at class level the object-class-definition (where configuration values are defined).

package com.demo.config.core;

import org.apache.sling.settings.SlingSettingsService;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.ConfigurationPolicy;
import org.osgi.service.component.annotations.Reference;
import org.osgi.service.metatype.annotations.Designate;


@Component(service = MySimpleService.class,configurationPolicy=ConfigurationPolicy.REQUIRE)
@Designate(ocd = MyServiceConfiguration.class)
public class MySimpleServiceImpl implements MySimpleService {



private MyServiceConfiguration config;

private boolean author;

@Reference
private SlingSettingsService settings;

@Activate
public void activate(MyServiceConfiguration config) {
this.config = config;
author = settings.getRunModes().contains("author");
}

public String getSimpleValue() {
return "hello " + config.configValue();
}

public boolean isAuthor() {
return author;
}

}
