Hey guys,

I am using AEM 6.5 and I've deployed a custom OSGI service config. I was expecting to find the config under http://localhost:4502/system/console/configMgr

Here is my Service.

MyService.java

public interface MyService {

    /**
     * This method returns the entered password into a hash equivalent with some
     * properties passed by the user
     *
     * @Param type
     * @Return {@link String}
     */
    String getPassword(String type);
}

MyServiceImpl.java

@Component(service = MyService.class,
        property = {
                "label=My Service Implementation"
        }
)
@Designate(ocd = MyConfiguration.class)
public class MyServiceImpl implements MyService {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    // Two properties to be read
    private String propertyOne;
    private String propertyTwo;

    @Activate
    protected void activate(MyConfiguration config) {
        // Reading properties from the configuration
        propertyOne = config.getPropertyOne();
        propertyTwo = config.getPropertyTwo();

    }

    @Override
    public String getPassword(String type) {

        // MD5 equivalent of password string
        String passwordHash = null;

        try {

            type = type + propertyOne + propertyTwo;

            log.info("Resulant password: " + type);

            // Convert string to bytes - this is for the sample implementation (for show casing)
            byte[] passwordByte = type.getBytes("UTF-8");

            // Getting instance of MessageDigest
            MessageDigest md = MessageDigest.getInstance("MD5");

            // Convert bytes array to hash using MD5 algorithm
            byte[] digest = md.digest(passwordByte);

            passwordHash = new String(digest);

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }

        return passwordHash;
    }

}

MyConfiguration.java

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

@ObjectClassDefinition(name = "My Configuration",
        description = "This configuration will be used to read the value of properties.")
public @interface MyConfiguration {

    @AttributeDefinition(name = "Property One", description = "Read property one", type = AttributeType.STRING)
    public String getPropertyOne() default "Property One";

    @AttributeDefinition(name = "Property Two", description = "Read property two", type = AttributeType.STRING)
    public String getPropertyTwo() default "Property Two";
}
