Re: [jersey-dev] Internal request with new UriInfo
|
In Jersey, you can have something like:
public static class SubResource {
private UriInfo uriInfo;
public SubResource(@Context UriInfo info) {
this.uriInfo = info;
}
@GET public String get() {
return uriInfo.getAbsolutePath().toASCIIString();
}
}
@Path("/")
public static class Resource {
@Path("/sub")
public Class<SubResource> getSub() {
return SubResource.class;
}
}
Would that help?

Thanks. Yes I instantiate Resource on my own.
It’s because in 2.x there does not seem to be any mechanism to lookup
resource by URI? While in 1.x there was ResourceContext.matchResource():

The issue is now 7 years old - how come it’s not implemented in 2.x?
So I need my own UriInfo implementation? Or can I reuse one somehow?

that you
need to instantiate the correct UriInfo on your own, too.
For the sub-resource case, JAX-RS Spec. Section 3.2 says: Objects
returned by sub-resource locators (see Section 3.4.1) are expected
to be
initialized by their creator.
