Subject [jira] [Commented] (FELIX-2961) @Component annotation should support defining the name with a compile time constant (instead of just a constant value)
Date Thu, 09 Jun 2011 14:48:58 GMT

    [ https://issues.apache.org/jira/browse/FELIX-2961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046588#comment-13046588
] 

Andrei Pozolotin commented on FELIX-2961:
-----------------------------------------

same request applies to class-level @Property:

in this snippet:

@Component
@Property( name = EventConstants.EVENT_TOPIC, value = { EventAPI.OPEN, EventAPI.CLOSED } )
public class TestCentralLoginResponse {

again, value = { EventAPI.OPEN, EventAPI.CLOSED ) must be a compile-time constant, which is
no good.

>             Project: Felix
>          Issue Type: New Feature

>            Reporter: Andrei Pozolotin

> hello!
> when I use config admin to control instaniation of scr component services, I use this
pattern:
> // 1) in config source bundle:
> 			Configuration config = configAdmin.getConfiguration("ZZZ", null);
> 			Dictionary<String, String> props = config.getProperties();
> 			config.update(props);
> //  2) in config target bundle:
> @Service
> @Component(name = "AAA", policy = ConfigurationPolicy.REQUIRE, immediate = true)
> public class BucketPlugin implements PluginSpaceService {
> 	@Property(name = "service.pid")
> 	protected static final String PID = "ZZZ";
> // 3) despite the fact service.pid "looks good" in xml for the tagret compenent:
>     <scr:component enabled="true" immediate="true" name="AAA" configuration-policy="require">
>         <implementation class="com.ddfplus.core.space.BucketPlugin"/>
>         <service servicefactory="false">
>             <provide interface="com.ddfplus.api.plugin.PluginSpaceService"/>
>         </service>
>         <property name="service.pid" type="String" value="ZZZ"/>
> // 4) the scr fails to initialize the component; intitialzation works only when 
> (scr.component.name == config.service.pid) and NOT when (config.service.pid == scr.component.property.pid)
> // 5) if I look on the the config target in console (when I do manage to inititialize
it),
> it shows that again, actual service.pid comes from scr.component.name and not from scr.component.property.service.pid
> thank you.
