私は2つの他のテーブル間で単純な "結合テーブル"を使用してHibernate 4を使用しています。あなたは2つの類似のテーブル、単純なIDに加えて名前を見ることができるようにJPA/Hibernate:JDBC呼び出しの引数が無効です:パラメータインデックスが範囲外です
@Entity
@Table(name = "Companies")
public class Company
{
@Id
@Column
private Integer id;
@Column
private String name;
...
}
と
@Entity
@Table(name = "PQs")
public class PQ implements Serializable
{
@Id
@Column
private Integer id;
@Column
private String name;
...
}
:ここではJPA 1.0互換性の実体です。今の相互接続エンティティ:
@Entity
@Table(name = "Partnerships")
@IdClass(value = PartnershipId.class)
public class Partnership implements Serializable
{
@Id
@Column(name = "pq_id", insertable = false, updatable = false)
private Integer pqId;
@Id
@Column(name = "company_id", insertable = false, updatable = false)
private Integer companyId;
@Column(name = "ordinal_nbr")
private Integer ordinalNbr;
@ManyToOne
@JoinColumn(name = "pq_id", referencedColumnName = "id")
private PQ pq;
@ManyToOne
@JoinColumn(name = "company_id", referencedColumnName = "id")
private Company company;
...
}
注意ここ@Column
に... , insertable = false, updatable = false
。次のテストコード
public class Main
{
private static String PERSISTENCE_UNIT_NAME = "standalonePu";
private static EntityManagerFactory emf;
private static EntityManager em;
private static EntityTransaction trans;
public static void main(String[] args)
{
setUp(PERSISTENCE_UNIT_NAME);
trans.begin();
PQ detachedPq = new PQ(1, "Test PQ");
Company detachedCompany = new Company(1, "Test Company");
PQ pq = em.merge(detachedPq);
Company company = em.merge(detachedCompany);
Partnership detachedPartnership = new Partnership(1, 1, 1);
detachedPartnership.setPQ(pq);
detachedPartnership.setCompany(company);
Partnership partnership = em.merge(detachedPartnership);
partnership = em.find(Partnership.class, new PartnershipId(1, 1));
System.out.println("Persistent partnership = ("
+ partnership.getPQId() + ", "
+ partnership.getCompanyId() + ", "
+ partnership.getOrdinalNbr() + ")");
trans.commit();
close();
}
private static void setUp(String puName)
{
emf = Persistence.createEntityManagerFactory(puName);
em = emf.createEntityManager();
trans = em.getTransaction();
}
private static void close()
{
em.close();
emf.close();
}
}
を実行している場合
public class PartnershipId implements Serializable
{
private Integer pqId;
private Integer companyId;
public PartnershipId()
{
}
public PartnershipId(Integer pqId, Integer companyId)
{
this.pqId = pqId;
this.companyId = companyId;
}
...
}
... Hibernateはtrans.commit();

テストの構成は、Hibernate 4.0.0.CR4ですHSQLDB 2.0などです。また、と非常に同じ JDBC例外を使用してMySQL 5でこれをテストしましたので、明らかにHibernateは間違ったコードを生成しています。
これを解決するための回避策は、..., insertable = false, updatable = false
を関係「@JoinColumn
」に入れることですが、実際には私が望むものではありません。
これはHibernateのバグですか?上記のコードは...
HibernateはIdClassと複数の@Idプロパティの使用を本当に推奨しません。これは、コンポーネントタイプを使用して表現された方がはるかに良いでしょう。 –
あなたの声明の参考資料はありますか?上記は単純なJPA 1.0であり、Hibernateはバージョン3.5からJPA 2.0互換であると主張しています。注意してください、私はここ(JPA)ポータブルでいたいです。 – Kawu
