----------------------------------
Summary: Make sure global JAX-RS filters are applied once per
request even if made to sub-resource
Key: CXF-6321
URL: https://issues.apache.org/jira/browse/CXF-6321
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 3.0.4
Reporter: Dmitry Kozlov
As of now CXF JAX-RS implementation applies global filters once per each
(sub-)resource level.
E.g. with resources defined as below any global filter is applied twice on a
call to sub-resource:
{code}
@Path("/groups")
public interface GroupsResource {
@Path("/{id}/members")
MembersResource membersOf(@PathParam("id") String id);
}
-----
public interface MembersResource {
@GET
@Path("/{memberId}")
MemberInfo get(@PathParam("memberId") String id);
}
GET http://example.com/groups/123/members/456
{code}
This may feel counter-intuitive in some cases and introduces certain overhead.
E.g. if you have your auth-filter defined as global.
Following our conversation in CXF-6297 could you please consider to change
filter chain logic so that global filters are applied once per request
disregard whether this request is made to a root resource or to a sub-resource
of any level.
Filter should be called with a full request context including actual URI info
and path params, as it would be a last filter invocation in current
implementation. E.g. in example above {{uriInfo}} should be passed as
{{/groups/123/members/456}} (not {{/main/123/members}}), and path params should
have both {{id}} and {{memberId}}.
