如何获取root @Path的PathSegment

Question

使用以下资源类

@Path("/cities")
public class CitiesResource {

    public Response read(
        @PathParam("???") final PathSegment path) {

        // ...
    }
}

如何为根PathSegment获取@Path("/cities")？

Answer 1

您可以从UriInfo.getPathSegments()

获取所有PathSegment

@GET
public String read(@Context UriInfo info) {
    List<PathSegment> segments = info.getPathSegments();
}
