我有一個大問題，我花了兩天的時間來解決這個問題。 我想添加兩個實體之間的新關係。第一個實體是User，第二個實體是UserType。我想創建@OneToMany的關係，所以我的這部分代碼添加到User類：缺少列模式驗證
@JsonIgnore
@OneToMany(mappedBy = "user")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<UserType> userTypes;
，我也加入到第二類：
@ManyToOne
private User user;
當然，我創建了一個新列它在user_type表上調用user_id，並在此列上添加外鍵。
但是，當我試圖運行我的應用程序我得到這個錯誤：

我使用Jhipster，我應該怎麼辦找到解決辦法？我究竟做錯了什麼？
編輯：UserType 類別：
@Entity
@Table(name = "user_type")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class UserType implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@NotNull
@Column(name = "type", nullable = false)
private String type;
@ManyToMany
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@JoinTable(name = "user_type_event",
joinColumns = @JoinColumn(name="user_types_id", referencedColumnName="ID"),
inverseJoinColumns = @JoinColumn(name="events_id", referencedColumnName="ID"))
private Set<Event> events = new HashSet<>();
@ManyToMany
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@JoinTable(name = "user_type_prelection",
joinColumns = @JoinColumn(name="user_types_id", referencedColumnName="ID"),
inverseJoinColumns = @JoinColumn(name="prelections_id", referencedColumnName="ID"))
private Set<Prelection> prelections = new HashSet<>();
@ManyToOne
private User user;
}
類User：
@Entity
@Table(name = "jhi_user")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class User extends AbstractAuditingEntity implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@NotNull
@Pattern(regexp = Constants.LOGIN_REGEX)
@Size(min = 1, max = 50)
@Column(length = 50, unique = true, nullable = false)
private String login;
@JsonIgnore
@NotNull
@Size(min = 60, max = 60)
@Column(name = "password_hash",length = 60)
private String password;
@Size(max = 50)
@Column(name = "first_name", length = 50)
private String firstName;
@Size(max = 50)
@Column(name = "last_name", length = 50)
private String lastName;
@Email
@Size(max = 100)
@Column(length = 100, unique = true)
private String email;
@NotNull
@Column(nullable = false)
private boolean activated = false;
@Size(min = 2, max = 5)
@Column(name = "lang_key", length = 5)
private String langKey;
@Size(max = 20)
@Column(name = "activation_key", length = 20)
@JsonIgnore
private String activationKey;
@Size(max = 20)
@Column(name = "reset_key", length = 20)
private String resetKey;
@Column(name = "reset_date", nullable = true)
private ZonedDateTime resetDate = null;
@JsonIgnore
@ManyToMany
@JoinTable(
name = "jhi_user_authority",
joinColumns = {@JoinColumn(name = "user_id", referencedColumnName = "id")},
inverseJoinColumns = {@JoinColumn(name = "authority_name", referencedColumnName = "name")})
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<Authority> authorities = new HashSet<>();
@JsonIgnore
@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "user")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<PersistentToken> persistentTokens = new HashSet<>();
@JsonIgnore
@OneToMany(mappedBy = "user")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private Set<UserType> userTypes;
}
看來一對多註釋應該是在用戶等級和積分類和多對一的User類。讓我們看一下User和UserType類的完整代碼。 – Rinat
但是爲什麼？ 'User'可以包含許多'UserTypes'，爲什麼'User'類必須只有一個'UserType'而'UserType'必須包含'User'集合？ – Ice
