In my Spring Boot / Data / JPA application, I have the following object:
@Entity @NamedEntityGraph(name = "graph.User", attributeNodes = { @NamedAttributeNode("authorities") }) @Table(name = "users") public class User extends BaseEntity implements UserDetails { private static final long serialVersionUID = 8884184875433252086L; @Id @SequenceGenerator(name = "users_id_seq", sequenceName = "users_id_seq", allocationSize = 1) @GeneratedValue(strategy = GenerationType.AUTO, generator = "users_id_seq") private Long id; ... @JsonIgnore @ManyToMany(fetch = FetchType.LAZY) @JoinTable(name = "users_authorities", joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "authority_id") }) private Set<Authority> authorities = new HashSet<Authority>(); }
This is my Spring AuthenticationService :
@Service public class AuthenticationService implements UserDetailsService { @Autowired private UserService userService; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { User user = userService.findByUsername(username); if (user == null) { throw new UsernameNotFoundException(String.format("User %s does not exist!", username)); } return user; } }
When the application starts, I get the following exception:
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.example.common.model.user.User.authorities, could not initialize proxy - no Session at
