春データエラー：少なくとも1つのJPAのメタモデルが

Question

存在している必要がありますそれはあなたが見ることができるように私はUserモデルを持つスタックトレースでAt least one JPA metamodel must be present!しかし言う：

@Entity 
@Table(catalog = "profiles", name = "users") 
@NoArgsConstructor 
public class User extends BaseEntity { 

    @Id 
    @GeneratedValue(generator = "UUID") 
    @GenericGenerator(
      name = "UUID", 
      strategy = "org.hibernate.id.UUIDGenerator" 
    ) 
    @Column(name = "uid", unique = true, updatable = false, nullable = false, length = 36) 
    private UUID uid; 

    //..... 

私はこれをどのように修正することができます起動時に発生するエラー？

Answer 1

、それはあなたが二つの異なるバネのデータライブラリを使用しているように、春・データ・releasetrainと春・ブート・スターター・データ-JPAです。

あなたが使用しているものが見つからない可能性がありますので、エラーになります。あなたは最初のものを削除することができます。
