Same issue when moving @PUT to the abstract class:
@javax.ws.rs.PUT
@javax.ws.rs.Path("/{id}")
public void update(@javax.ws.rs.PathParam("id") long id, User user)
{ ... }

Hey Sergey,
I do not know what the reason is, all I know is that if I have:
@POST public void add(User user) {...}
In the regular class, it works, but if I move the code to the abstract
class and make it generic, like so:
@POST public void add(T user) {...}
then I get the exception. But it works ok for @GET list(), or @GET
find(long id).

PS: Please note my typo in the initial post that the abstract class
does not know "User" but only the generic "T".

Hi,
So just to confirm, for the purpose of writing a test,
@Path(...)
@Produces(...)
UserServiceImpl extends AbstractServiceImpl<User>
implements UserService
{
}
abstract class AbstractServiceImpl<T> {
{
@POST
public void add(User user) {...// reflection ...//}
}
can not be matched with 'User' add parameter being confused for Object ?
If no then please correct me...
I'll do a test shortly
Cheers, Sergey

Subject: Inheriting methods
I have to implement basic CRUD operations on a serious number of
Entities. The to-be-executed code is identical for all classes,
except that different DAO implementating classes are involved. So I
decided to go for reflection, so instead of:
/@Path(...)
@Produces(...)
implements UserService
UserServiceImpl
{
@GET
public void list() {... same code over and over again... }
@POST
public void add(User user) {... //same code over and over
again... //}
}
/
I have
/@Path(...)
@Produces(...)
UserServiceImpl extends AbstractServiceImpl<User>
implements UserService
{
}
abstract AbstractServiceImpl<T>
{
@GET
public void list() {... reflection ...}
@POST
public void add(User user) {...// reflection ...//}
}
/
This works fine for REST-GET but not for REST-POST, there I get a
"No message body reader found for request class : Object,
ContentType : text/xml". This most definitely has to do with the
resolving of the @POST, because if I add the code below the the
UserServiceImpl, then it all works ok.
/ @POST public void add(User user) { super.add(user); }
/Any suggestions on why?
Tom
