JPAエンティティグラフによる動的フェッチでSQLGrammarExceptionがスローされる

Spring SecurityとHibernateを使用して基本的なユーザー管理を実装しました。ここでJPAエンティティグラフによる動的フェッチでSQLGrammarExceptionがスローされる

は、それらの関係（UserEntity、RoleEntity、PermissionEntity、UserRoleEntityとUserPermissionEntity）とのエンティティです：

UserEntity：

@Entity 
@Table(name = "tb_user") 
@NamedQuery(name = "User.findById", query = "SELECT u FROM UserEntity u WHERE u.idUser = :userId") 
@NamedEntityGraph(
    name = "graph.userRoles.role", 
    attributeNodes = { 
     @NamedAttributeNode(value = "userRoles", subgraph = "userRolesGraph"), 
     @NamedAttributeNode(value = "userPermissions", subgraph = "userPermissionsGraph") 
    }, 
    subgraphs = { 
     @NamedSubgraph(name = "userRolesGraph", attributeNodes = @NamedAttributeNode("role")), 
     @NamedSubgraph(name = "userPermissionsGraph", attributeNodes = @NamedAttributeNode("permission")) 
    } 
) 
public class UserEntity implements Serializable 
{ 
    [...] 

    @OneToMany(mappedBy = "user", fetch = FetchType.LAZY) 
    private Set<UserRoleEntity> userRoles; 
    @OneToMany(mappedBy = "user", fetch = FetchType.LAZY) 
    private Set<UserPermissionEntity> userPermissions; 

    [...] 
}

UserRoleEntity：

@Entity 
public class UserRoleEntity implements Serializable 
{ 
    [...] 

    @JoinColumn(name = "id_role", referencedColumnName = "id_role") 
    @ManyToOne(fetch = FetchType.LAZY) 
    private RoleEntity role; 
    @JoinColumn(name = "id_user", referencedColumnName = "id_user") 
    @ManyToOne(fetch = FetchType.LAZY) 
    private UserEntity user; 

    [...] 
}

UserPermissionEntity：

@Entity 
public class UserPermissionEntity implements Serializable 
{ 
    [...] 

    @JoinColumn(name = "id_user", referencedColumnName = "id_user") 
    @ManyToOne(fetch = FetchType.LAZY) 
    private UserEntity user; 
    @JoinColumn(name = "id_permission", referencedColumnName = "id_permission") 
    @ManyToOne(fetch = FetchType.LAZY) 
    private PermissionEntity permission; 

    [...] 
}

私はちょうどそのIDを持つ特定UserEntityを取得し、取得したい：

：

UserEntity.userRoles.role
UserEntity.userPermissions.permission

はここダオの方法があります

@Override 
@Transactional(readOnly = true) 
public UserEntity getUserByIdGraph(Integer userId) 
{ 
    TypedQuery<UserEntity> query = this.entityManager.createNamedQuery("User.findById", UserEntity.class); 

    query.setParameter("userId", userId); 
    query.setHint("javax.persistence.fetchgraph", 
      this.entityManager.getEntityGraph("graph.userRoles.role")); 
    UserEntity userEntity = query.getSingleResult(); //Fails here 

    return (userEntity); 
}

問題は次のとおりですROR：

私は別にちょうどuserRoles.roleまたはuserPermissions.permissionをフェッチする場合、それは動作しますので、何が起こっているか理解していません。しかし、2つのサブグラフは一緒に失敗します（これはjavax.persistence.loadgraphを使って同じです）！

私は本当に迷っています。

PS：attributePathsを使用して@EntityGraphアノテーションを使用しようとしましたが、NetBeansで認識できませんでした。 @EntityGraphアノテーションを使用するための適切なMavenパッケージを知っていますか？

ありがとうございました！

'は、JPA 2.1のためのjavax.persistenceであります –

これはあなたの質問には直接言及していないことは知っていますが、アプリケーション設計ノートとして指摘しておく必要があります。ユーザー< - >役割（UserRoleEntity）とユーザー< - >権限（UserPermissionEntity）の間のエンティティ関係を記述するためにエンティティを使用しているようです。これらのマッピングを簡素化するために@JoinTablesの使用を検討しましたか？

例：EntityGraph` @

@Entity 
public class UserEntity implements Serializable { 
    @OneToMany 
    @JoinTable(name="USER_ROLE", 
     joinColumns= @JoinColumn(name="USER_ID"), 
     inverseJoinColumns= @JoinColumn(name="ROLE_ID")) 
    private Set<RoleEntity> userRoles; 

    @OneToMany 
    @JoinTable(name="USER_PERM", 
     joinColumns= @JoinColumn(name="USER_ID"), 
     inverseJoinColumns= @JoinColumn(name="PERM_ID")) 
    private Set<PermissionEntity> userPermissions; 
} 

@Entity 
public class RoleEntity { 
    @ManyToOne 
    @JoinTable(name = "USER_ROLE", 
     joinColumns = @JoinColumn(name = "ROLE_ID"), 
     inverseJoinColumns = @JoinColumn(name = "USER_ID")) 
    private UserEntity user; 
} 

@Entity 
public class PermissionEntity { 
    @ManyToOne 
    @JoinTable(name = "USER_PERM", 
     joinColumns = @JoinColumn(name = "PERM_ID"), 
     inverseJoinColumns = @JoinColumn(name = "USER_ID")) 
    private UserEntity user; 
}
