Selecting latest workout set by user - spring

Question

I'm trying to select the latest added workout set associated with a given user.
Users has sessions and sessions has sets. My entities are defined as below.
#Entity(name = "users") // Postgres doesn't like the table name "user"
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
#OneToMany(mappedBy = "user")
private Set<Session> sessions;
...
#Entity
public class Session {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
#ManyToOne
private User user;
#OneToMany(mappedBy = "session")
private Set<WorkoutSet> sets;
...
#Entity
public class WorkoutSet {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
#OneToOne
private User user;
#ManyToOne
private Session session;
private LocalDateTime timestamp = LocalDateTime.now();
...
The following sql query seems to do the trick
select w
from workout_set w
inner join session s
on w.session_id = s.id
where s.user_id = 1
order by w.timestamp DESC
limit 1
But when I'm trying to do something like the below
#Repository
public interface WorkoutSetRepository extends CrudRepository<WorkoutSet, Long> {
#Query("select w from WorkoutSet w inner join Session s on w.session_id = s.id where s.user = :user order by w.timestamp")
List<WorkoutSet> findLastSet(User user, Pageable limit);
I get...
org.springframework.data.mapping.PropertyReferenceException: No property user found for type WorkoutSet!
Any clues about how to do the query right? I'm very open to alternative ways as well because I'd rather avoid writing jpql if possible.

Answer 1

Try this:
#Repository
public interface WorkoutSetRepository extends CrudRepository<WorkoutSet, Long> {
#Query("select w from WorkoutSet w inner join w.session s where s.user = :user order by w.timestamp")
List<WorkoutSet> findLastSet(#Param("user") TestUser user);
}
Note the difference in the join clause. This works with hibernate 5.0.11.
