具有惰性关系的Spring数据JPA克隆实体

我有实体:

@Data
@Entity
@Table(name = "USERS")
public class User{

    @Id
    @Column(name = "GUID", nullable = false)
    private String guid;

    @OneToMany(mappedBy = "user", cascade = {CascadeType.PERSIST, CascadeType.MERGE}, fetch = LAZY)
    private List<Role> roles;

    @OneToMany(mappedBy = "user", fetch = LAZY, cascade = {CascadeType.ALL})
    private List<Person> persons;

usersRepository.detach(user);

但我找不到 roles persons 因为它 LAZY

    user.getRoles().size();
    user.getPersons().size();
    usersRepository.detach(user);

但我不喜欢。我能让它更容易些吗?
