StackOverflowError after adding user field

Question

@Data
@Entity
@Table(name = "users")
@ToString(exclude = "password")
@NoArgsConstructor
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;


@ManyToMany(cascade = {CascadeType.REFRESH, CascadeType.MERGE})
@JoinTable(name = "user_to_role",
        joinColumns = @JoinColumn(name = "user_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id"))
private Set<Role> roles;
}

in my code users have a role field, I decided to add users field to the roles entity.I need this in order not to contact the database every time to search for users, if there are roles. I want to get a list of id of users who have this role, without the rest of the fields. As I understand it, lazy loading will help me with this, but I'm not sure(I haven't had time to test yet). When I try to log in, I get the following error, I suppose it is due to spring security, I don't understand

@Data
@Entity
@Table(name = "roles")
@NoArgsConstructor
public class Role {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;


@ManyToMany
@JoinTable(name = "user_to_role",
        joinColumns = @JoinColumn(name = "user_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id"))
private Set<User> users;
}

this is repeated a huge number of times, I did not insert. thanks in advance there is a user_to_role table in the database and an entry in it

@JsonIgnore
@ManyToMany
@JoinTable(
        name = "user_to_role",
        joinColumns = {@JoinColumn(name = "user_id", referencedColumnName = "id")},
        inverseJoinColumns = {@JoinColumn(name = "role_id", referencedColumnName = "id")})
private Set<Role> roles;

Can you try like this in the User entity, and the Vice Versa(inverseJoin and join based on entity) on Role Entity side also.

And please ensure that either of the entity should load/Fetch this property in a Lazy mode otherwise there will be an infinite loop of references that are ready to fetched.

@ManyToMany(fetch = FetchType.LAZY)

The above should be done on at least one of the cross referenced entities.

My code uses the annotation @Data, which generates hashCode and ToString methods and this structure leads to Hibernate stuck. in my case I just added the exclusion parameters, like @EqualsAndHashCode(exclude="dependent_list")
