Tipe Hibernasi, Postgres &Array

Saya mencoba beberapa versi berdasarkan Jenis Array yang diperkenalkan oleh JDBC4 :Bagaimana saya bisa mengatur parameter String[] ke kueri asli?. Masalahnya juga Hibernate (bahkan di versi terakhir 4.3.1.final) tidak berfungsi dengan fitur baru ini dan memberi saya pesan kesalahan berikut

Could not determine a type for class: org.postgresql.jdbc4.Jdbc4Array

Jadi saya harus membuat Specific UserType (berdasarkan beberapa artikel di stackoverflow, dan sumber lain)

Model Saya

@Type(type = "fr.mycompany.dao.hibernate.types.ArrayUserType")
private String[] values;

ArrayUserType saya

public class ArrayUserType implements UserType {

/** Constante contenant le type SQL "Array".
 */
protected static final int[] SQL_TYPES = { Types.ARRAY };

/**
 * Return the SQL type codes for the columns mapped by this type. The
 * codes are defined on <tt>java.sql.Types</tt>.
 * 
 * @return int[] the typecodes
 * @see java.sql.Types
 */
public final int[] sqlTypes() {
    return SQL_TYPES;
}

/**
 * The class returned by <tt>nullSafeGet()</tt>.
 * 
 * @return Class
 */
public final Class returnedClass() {
    return String[].class;
}

/**
 * Retrieve an instance of the mapped class from a JDBC resultset. Implementors
 * should handle possibility of null values.
 * 
 * @param resultSet a JDBC result set.
 * @param names the column names.
 * @param session SQL en cours.
 * @param owner the containing entity 
 * @return Object
 * @throws org.hibernate.HibernateException exception levée par Hibernate
 * lors de la récupération des données.
 * @throws java.sql.SQLException exception SQL 
 * levées lors de la récupération des données.
 */
@Override
public final Object nullSafeGet(
        final ResultSet resultSet, 
        final String[] names, 
        final SessionImplementor session, 
        final Object owner) throws HibernateException, SQLException {
    if (resultSet.wasNull()) {
        return null;
    }

    String[] array = (String[]) resultSet.getArray(names[0]).getArray();
    return array;
}

/**
 * Write an instance of the mapped class to a prepared statement. Implementors
 * should handle possibility of null values. A multi-column type should be written
 * to parameters starting from <tt>index</tt>.
 * 
 * @param statement a JDBC prepared statement.
 * @param value the object to write
 * @param index statement parameter index
 * @param session sql en cours
 * @throws org.hibernate.HibernateException exception levée par Hibernate

 */
@Override
public final void nullSafeSet(final PreparedStatement statement, final Object value, 
        final int index, final SessionImplementor session) throws HibernateException, SQLException {

    if (value == null) {
        statement.setNull(index, SQL_TYPES[0]);
    } else {
        String[] castObject = (String[]) value;
        Array array = session.connection().createArrayOf("text", castObject);
        statement.setArray(index, array);
    }
}

@Override
public final Object deepCopy(final Object value) throws HibernateException {
    return value;
}

@Override
public final boolean isMutable() {
    return false;
}

@Override
public final Object assemble(final Serializable arg0, final Object arg1)
        throws HibernateException {
    // TODO Auto-generated method stub
    return null;
}

@Override
public final Serializable disassemble(final Object arg0) throws HibernateException {
    // TODO Auto-generated method stub
    return null;
}

@Override
public final boolean equals(final Object x, final Object y) throws HibernateException {
    if (x == y) {
        return true;
    } else if (x == null || y == null) {
        return false;
    } else {
        return x.equals(y);
    }
}

@Override
public final int hashCode(final Object x) throws HibernateException {
    return x.hashCode();
}

@Override
public final Object replace(
    final Object original,
    final Object target,
    final Object owner) throws HibernateException {
    return original;
}

}

Dan yang terakhir, tetapi paling tidak (itulah yang saya lewatkan):ketika saya perlu menjalankan SQL Native Query, saya harus memaksa tipe parameter dengan sintaks berikut

String[] values = ...
Type arrayType = new CustomType(new ArrayUserType());
query.setParameter("value", values, arrayType);
