[jboss-jira] [JBoss JIRA] (WFLY-7210) Expose JAX-RS resources as children of the subsystem

[Lin Gao (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13324091#comment-13324091 ] 

Lin Gao commented on WFLY-7210:
-------------------------------

[~ggam] I am really sorry for the late reply. :-)

What was concerned when implementing WFLY-7024 without more level of sub resources is that it may produce too much resources and sub-resources in case of large deployments in memory. And the REST endpoints information will probably be parsed during deployment time, which will potentially impact the deployment time.

Current design is that each root REST resource is added during deployment by {{JaxrsScanningProcessor}} without further analyzing inside of the ResourceClass. The {{:read-resource()}} operation will read the information in {{ResourceMethodRegistry}} exposed by {{HttpServletDispatcher}} at run-time.

Is it possible that the web console can parse the data for the jaxrs subsystem to customize the UI as we want? 

[~mkopecky] [~harald.pehl] WDYT?

> Servlets, EJBs, WebSockets, JPA, etc expose its components as children of the subsystem in the management API. For example to list the stateless EJBs of a deployment: 
> [standalone at localhost:9990 /] /deployment=cdivsejb.war/subsystem=ejb3:read-children-resources(child-type=stateless-session-bean)
> This makes it specially easy to navigate trough the web console (attached screenshot).
> To read JAX-RS resources, the command would be:
> [standalone at localhost:9990 /] /deployment=cdivsejb.war/subsystem=jaxrs:show-resources()
> I propose to make deprecate the show-resources operation and create a new "resources" child, containing the Rest resources.
