JPARepository - delete using date comparison with derived query - postgresql

Question

I'm trying to use JPARepository in Spring Boot to delete records that are less than a certain date, for for a given userid
Should be something like this Delete * from [table] where expiration_date < [date] and userid = [userid]
I thought I should be able to use one of the automatically generated methods
int deleteByExpiryDateBeforeAndUser(Date date, User user);
But this is generating a Select and not a Delete. What am I doing wrong?
Update
Entity class
#Getter
#Setter
#ToString
#Entity(name = "refresh_token")
public class RefreshToken {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#OneToOne
#JoinColumn(name = "user_id", referencedColumnName = "id")
private User user;
#Column(nullable = false, unique = true)
private String token;
#Column(nullable = false)
private Date expiryDate;
public RefreshToken() {
}
}
Repository class
#Repository
public interface RefreshTokenRepository extends JpaRepository<RefreshToken, Long> {
Optional<RefreshToken> findByToken(String token);
#Modifying
void deleteByUserIdAndExpiryDateBefore(Long userId, Date expiryDate);
int deleteByUser(User user);
}
Here's how I'm calling it
#Transactional
public void deleteExpiredTokens(User user) {
refreshTokenRepository.deleteByUserIdAndExpiryDateBefore(user.getId(), new Date());
}

You see a select statement because Spring Data first loads entities by condition.
Then once entities became 'managed' Spring Data issues a delete query for each entity that was found.
If you want to avoid redundant SQL query - you have to consider #Query annotation.
Then your code will look like this:
#Repository
public interface RefreshTokenRepository extends JpaRepository<RefreshToken, Long> {
// ...
#Query(value = "DELETE FROM refresh_token WHERE user_id =:userId AND expiry_date < :expiryDate", nativeQuery = true)
#Modifying
void deleteByUserIdAndExpiryDateBefore(Long userId, Date expiryDate);
//...
}
