我有以下几点。

@Data
@Getter
@Setter
@Accessors(fluent = false, chain = true)
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode(onlyExplicitlyIncluded = true)
@MappedSuperclass
@Slf4j
class Base {
  private Timestamp createdTime;
  private Timestamp modifiedTime;
  private String createdBy;
  private String modifiedBy;
  private Boolean deleted = false;
}

@Getter
@Setter
@Builder
@EqualsAndHashCode
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table(name = "account")
@SQLDelete(sql = "UPDATE account SET deleted = true WHERE account_id = ?")
@Where(clause = "deleted=false")
class Account {
  @Id
  @EqualsAndHashCode.Include()
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long accountId;

  @Builder.Default
  @OneToMany(fetch = FetchType.LAZY, mappedBy = "account", cascade = {CascadeType.ALL})
  private Set<Collab> collaborators = new HashSet<>(0);
  private String objId;
}

class Collab {
  @Id
  @EqualsAndHashCode.Include()
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long collabId;
  private String email;
  private String role;
  @JsonBackReference
  @JoinColumn(name = "accountId")
  @ManyToOne(fetch = FetchType.EAGER)
  private Account account;
}

public interface AccountRepo {
  Optional<Account> findByObjId(String objId);
}

字符串
即使数据库中的单个帐户有多个协作。当我检查AccountRepo.findByObjId（或findAll）方法的响应时，对于任何帐户对象，collaborators中只有1个元素。我错过了什么？
