Re: [Resteasy-developers] How the resources (@Path, ...) are scanned

[Weinan Li <we...@re...>]

Hi Charles,

Sorry I'm not sure whether I understand your question correctly, so please forgive me if I'm wrong :-)

To start a Resteasy container, first we need to create a ResteasyDeployment instance and initialize it:

ResteasyDeployment deployment = new ResteasyDeployment();
deployment.start();

Then we can register any resources into it:

deployment.getActualResourceClasses().add(SimpleResource.class);

Or you can also directly add into Registry class:

deployment.getRegistry().addPerRequestResource(Resource.class);

Because in ResteasyDeployment itself it's like:

if (resources != null)
{
   for (Object obj : resources)
   {
      registry.addSingletonResource(obj);
   }
}

for (Class actualResourceClass : actualResourceClasses)
{
   registry.addPerRequestResource(actualResourceClass);
}

for (ResourceFactory factory : resourceFactories)
{
   registry.addResourceFactory(factory);
}

All the scanners are implemented based on above logics. Here are some scanner examples:

https://github.com/wildfly/wildfly/blob/0c68aa0ebef3682e9ded4b473e24463b3e31af07/jaxrs/src/main/java/org/jboss/as/jaxrs/deployment/JaxrsScanningProcessor.java

Hope the info is useful to you :-)

I have been able to shade the Resteasy project in order to generate the OSGI MANIFEST file and to solve some TCCL issues like also to inject the BeanManager on OSGI but I can't use the option resteasy.scan = true
