HibernateとPostgreSQLにUserTypeを持つ配列 - > MappingException

Question

Hibernate/JPAの配列を扱うためにUserTypeを実装するクラスを記述しようとしています。 私は解決策を構築するのに mapping a postgres array with hibernateとHibernate/JPA/HSQL : How to create a Dialect mapping for User Type ARRAYの投稿を使用しましたが、動作させることができません。 私はテストするために新しいSpring Rooプロジェクトを作成しました。ここで（すべてのJavaクラスがパッケージテストに配置されている）別のファイルは、以下のとおりです。

だから私はその方言を推測私が作成したものはまったく使われていない間違っていますが、私は理由を知らない。私は@Typeアノテーションがマッピングを行うべきだと思うが、いくつかのタグを見たことがあるが、この例でそれらが必要かどうかわからない。私はこの問題に悩まされており、私は絶望的になっています。このプログラムのデバッグを手伝ってもらえますか？お願いします。 ありがとうございます。

編集0：

persistence.xmlファイルが正しい方言を見つけるように見えるが、関数getTypeNameメソッド（2003）registerHibernateType（Types.ARRAY、 "アレイ"）を行った後、上記のエラーがスローされます。ところで、私はHibernate 3.6.4.Finalとpostgresql 8.4-702.jdbc3を使用しています。

編集1：

私はPostgreSQLDialectArrayコンストラクタに次の行を追加しました：

registerColumnType(Types.ARRAY, "integer[$l]"); 

を部分的に問題を解決するために思われます。しかし、今、私は別のエラーが出る：

どうやら

2013-01-09 11:14:30,281 [main] ERROR org.hibernate.tool.hbm2ddl.SchemaExport - Unsuccessful: create table blabla (id int8 not null, array int[255], name varchar(255), test int4 not null, version int4, primary key (id))

、まだそれの配列を持つテーブルを作成する方法を知らないハイバネート...

編集2：

に思えますpostgresqlは私のカラムが "array"と呼ばれているのを気に入らなかった。私はそれを変更し、それは働いた。テーブルは、整数の配列でhibernateによって作成されます。

しかし、UserTypeの実装に問題があるため、hibernateで配列を保存することはできません。どうやら、配列の作成はcreateArrayOfで失敗します。私はこの問題について、ラッパーの代わりに基本的な接続にアクセスするように指示するいくつかのスレッドを読んでいます。この問題はかなり異なるので、私はこのスレッドにリンクする新しいスレッドを開こうと思っています。

最後に、次のような変形した後、整数配列のためのUserType作品：

• はApplicationContextのこの行を追加します。 xml：

  <bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" id="dataSource">
....
<property name="accessToUnderlyingConnectionAllowed" value="true" />
</bean>
  

• IntArrayUserType

  から

  @Override 
      public void nullSafeSet(final PreparedStatement statement, final Object object, final int i) throws HibernateException, SQLException { 
       Connection connection = statement.getConnection(); 
       int[] castObject = (int[]) object; 
       Integer[] integers = toObject(castObject); 
       Connection conn = ((DelegatingConnection) connection).getInnermostDelegate(); 
       Array array = conn.createArrayOf("integer", integers); 
       statement.setArray(i, array); 
      } 
  

をnullSafeSetを変更するが、テーブルのblablaからすべてのエントリを取得するときに問題がまだある。 関数findAllBlablasが正しく動作せず、返ります最初のエントリ...

編集4：

は実際には、それは素晴らしい仕事が、Eclipseのコンソールには、すべてのデータを印刷することができませんでした。それで全部です！

Answer 1

編集3のソリューションの横に、dbcpやc3p0のような接続プールを使用しないと完璧に動作します。 - dbcpを使用しています。

可能な解決策は、c3p0を使用する場合はproxoolを使用することです。これにより、proxoolはcreateArrayOf()を処理できるため、問題はありません。

もう一つは、このようになります：

C3P0ProxyConnection connection = (C3P0ProxyConnection) _statement.getConnection(); 
    Method method = Connection.class.getMethod("createArrayOf", new Class[] { String.class, Object[].class }); 
    Array array = (Array) connection.rawConnectionOperation(
     method, C3P0ProxyConnection.RAW_CONNECTION, new Object[] {"integer", intArray}); 
    _statement.setArray(_i, array); 

あなたは、JDBCクラスから基本的な機能を取得する必要があります。そのためにgetMethodとそれを取得し、反射でそれを使用してください。
