Spring JWT, missing information about role in database - mysql

Question

Architecture: Spring Boot, Spring JWT, Hibernate, MySQL
Current situation:
Properly generated jwt token during sign up user. Also I have no problem with login.
Problem:
I have problem with user roles. Properly was sent etc., but does not save to database.
I have user table:
#Entity
#Table(name="user")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="id")
private int id;
#Column(name="login")
private String login;
#Column(name="password")
private String password;
#Column(name="email")
private String email;
#ElementCollection(fetch = FetchType.EAGER)
#CollectionTable(name = "user_roles", joinColumns = #JoinColumn(name = "id"))
#Column(name="role")
List<Role> roles;
public User(){}
public User(String login, String password, String email, List<Role> roles) {
this.login = login;
this.password = password;
this.email = email;
this.roles = roles;
}
//getters and setters, toString();
}
Role enum:
public enum Role implements GrantedAuthority {
ROLE_ADMIN,
ROLE_USER
#Override
public String getAuthority() {
return name();
}
}
But where I use findByLogin User, there is no information about Role. But another information exist.
#Override
public User findByLogin(String loginUser) {
Session currentSession = entityManager.unwrap(Session.class);
Query findLoginQuery = currentSession
.createQuery("from User where login=:login")
.setParameter("login", loginUser);
return (User) findLoginQuery.uniqueResult();
