Jersey with unmarshalling responder face with HashSet field
I have a problem with Jersey
(2.13). I believe the problem is with the un-marshalling mechanism. My object User
has a field - a collection of objects Role
. When I try to get it, I get an error.
Here are my classes
@XmlRootElement(name = "user")
public class User {
private Set<Role> roleSet;
// other fields omitted
@XmlElementWrapper(name = "roles")
@XmlElement(name = "role")
public Set<Role> getRoleSet() { /* compiled code */ }
// all other getters with simple JAXB annotations @XmlElement omitted
}
Role
@XmlRootElement(name = "role")
public class ClientRole {
private String name;
private boolean active;
private String id;
@XmlElement(name = "name")
public String getName() { /* compiled code */ }
// all getters with JAXB annotations omitted
}
And my client client code is
HttpAuthenticationFeature authenticationFeature = HttpAuthenticationFeature.basic("freddy", "qwerty");
Client client = ClientBuilder
.newClient()
.register(authenticationFeature)
.register(JacksonFeature.class);
WebTarget target = client.target("http://localhost:4444/server/");
Response resp = target
.path("/api/users/freddy")
.request()
.accept(MediaType.APPLICATION_JSON)
.get();
User entity = resp.readEntity(User.class);
System.out.println(entity);
How can I fix this error? Or maybe I just forgot to register some new feature (for the new Jersey 2.13 release)?

Here are my dependencies

UPDATE 2
String entity = resp.readEntity(String.class);
{"name":"Bob","enabled":true,"roles":[{"name":"ADMIN","active":false,"id":12313214},{"name":"USER","active":true,"id":45353}]}

The problem is that when serializing you are probably using MOXy, which adds an extra wrapper element ( roles
in this case) that is not fully supported by Jackson.
You can use MOXy for client side de-serialization
Client client = ClientBuilder
.newClient()
.register(authenticationFeature)
.register(MoxyJsonFeature.class);
or slightly change the model class so that the JAXB (MOXy) serializer produces what Jackson is capable of de-serializing
@XmlElement(name = "roles")
public Set<Role> getRoleSet() {
return roleSet;
}
Finally, you can enable Jersey to use Jackson on the server side by registering JacksonFeature
:
@ApplicationPath("/")
public class TestApplication extends ResourceConfig {
public TestApplication() {
register(TestResource.class);
register(JacksonFeature.class);
}
}
