how to replace @properties annotation in aem 6.4 using OSGi R6 annotations

import org.apache.felix.scr.annotations.Component;

import org.apache.felix.scr.annotations.Properties;

import org.apache.felix.scr.annotations.Property;

import org.apache.felix.scr.annotations.Reference;

import org.apache.felix.scr.annotations.Service

@Component(label="Myproject Service")

@Properties({

@Property(name = Constants.SERVICE_RANKING, intValue = 400, propertyPrivate = true),

@Property(name = "priority", intValue = 200)

})

@Service({Myservice.class})

The felix scr annotations in aem 6.2 is now replaced with OSGi R6 annotations. But  how to replace it ?

I have tried one method. Please do let me know is it correct and how to use "properties" in OSGI R6.

import org.osgi.service.component.annotations.Reference;

import org.osgi.service.component.annotations.Component;

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

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

@Component(service=Myservice.class,immediate = true,name="Myproject Service",

property = {"Constants.SERVICE_RANKING="+"400","priority="+"200"  })

Is this correct ?

and how to use properties label in OSGi R6 ?

      here two samples that I made on this:

      Ranking: htl-examples/CustomBindingProvider.java at master · heervisscher/htl-examples · GitHub

      Service: htl-examples/MySimpleServiceImpl.java at master · heervisscher/htl-examples · GitHub

        Yes,  you need to declare new variables on top of it add AttributeDefinitions and you need to same variables name which were defined earlier

        You can use OCD Attribute definitions to convert this into OSGI

        EX :

        @AttributeDefinition(name = "Constants.SERVICE_DESCRIPTION", description = "Content Insights Page Name Resolver implementation")

        String getDescription();

        https://blog.osoco.de/2015/11/osgi-components-simply-simple-part-iii/

        http://keysandstrokes.info/aem-code-snippets-osgi-annotations/

        You need to follow below apprach if you want to convert as it is something like adding Prorperty = { key=value,key=value }

        Ex :

        @Component(metatype = true, immediate = true, label = "Content Insights Page Name Provider", description = "Service to use custom content insights page name variable")

        , Property = { Constants.SERVICE_DESCRIPTION  = "Content Insights Page Name Resolver implementation",

        Constants.SERVICE_RANKING, intValue = 200, propertyPrivate = false }

        @AttributeDefinition(name = "Feed Url", description = "Feed Url")
        String feedUrl();

        You need to declare Object Class Definitions(OCD).

        @Service

        @Component(metatype = true, immediate = true, label = "Content Insights Page Name Provider", description = "Service to use custom content insights page name variable")

        @Properties({

        @Property(name = Constants.SERVICE_DESCRIPTION, value = "Content Insights Page Name Resolver implementation"),

        @Property(name = Constants.SERVICE_RANKING, intValue = 200, propertyPrivate = false),

        @Property(name = "basePath", value = "/content/myproject/language-masters/en", description="The path to be removed from Content Insights URL", label="basePath"),

        @Property(name = "blogBasePath", value = "/content/myproject-blog/en", description="The path to be removed from Content Insights URL for Blogs", label="blogBasePath"),

        @Property(name = "cqVarContentInsight", value = "pagedata.path", description="The CQ variable used for Content Insights URL", label="cqVarContentInsight"),

        @Property(name = "langBasePath", value = "/content/myproject/language-masters", description="The path to be removed from Content Insights URL", label="langBasePath")})

        Could you please help me in this ?

        Hi,

        YOU can do like below:

        No need to put properties in quotes.

        @Component(service = MyService.class, immediate = true, property = {

        Constants.SERVICE_RANKING + "=400",

        "priority=200"

        })
