org.hibernate.MappingException: Нет Диалект отображения для типа JDBC: 2003

Question

public void GetLevel(int id) 
    { 
     Type doubleArrayType=new TypeLocatorImpl(new TypeResolver()) 
       .custom(DoubleArrayUserType.class); 
     Query query = sf.getCurrentSession(). 
       createSQLQuery("select waterLevel from FtpData"). 
       addScalar("waterLevel", doubleArrayType); 


     @SuppressWarnings("unchecked") 
     List<Double[]> results=(List<Double[]>) query.list(); 
     System.out.println("In dao layer data:"+results); 
     return; 
    } 

пытается получить доступ к БД, которая оказывает массив двойные, для которого я ВГ написанного типа пользовательского класс :::

package com.app.usertype; 

import org.apache.commons.lang3.ArrayUtils; 
import org.hibernate.HibernateException; 
import org.hibernate.engine.spi.SessionImplementor; 
import org.hibernate.usertype.UserType; 

import java.io.Serializable;

public class DoubleArrayUserType implements UserType { 
    protected static final int SQLTYPE = java.sql.Types.ARRAY; 

    @Override 
    public Object nullSafeGet(final ResultSet rs, final String[] names, final SessionImplementor sessionImplementor, final Object owner) throws HibernateException, SQLException { 
     Array array = rs.getArray(names[0]); 
     Double[] javaArray = (Double[]) array.getArray(); 
     return ArrayUtils.toPrimitive(javaArray); 
    } 

    @Override 
    public void nullSafeSet(final PreparedStatement statement, final Object object, final int i, final SessionImplementor sessionImplementor) throws HibernateException, SQLException { 
     Connection connection = statement.getConnection(); 

     double[] castObject = (double[]) object; 
     Double[] doubles = ArrayUtils.toObject(castObject); 
     Array array = connection.createArrayOf("DOUBLE", doubles); 

     statement.setArray(i, array); 
    } 

    @Override 
    public Object assemble(final Serializable cached, final Object owner) throws HibernateException { 
     return cached; 
    } 

    @Override 
    public Object deepCopy(final Object o) throws HibernateException { 
     return o == null ? null : ((double[]) o).clone(); 
    } 

    @Override 
    public Serializable disassemble(final Object o) throws HibernateException { 
     return (Serializable) o; 
    } 

    @Override 
    public boolean equals(final Object x, final Object y) throws HibernateException { 
     return x == null ? y == null : x.equals(y); 
    } 

    @Override 
    public int hashCode(final Object o) throws HibernateException { 
     return o == null ? 0 : o.hashCode(); 
    } 

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

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

    @Override 
    public Class<double[]> returnedClass() { 
     return double[].class; 
    } 

    @Override 
    public int[] sqlTypes() { 
     return new int[] { SQLTYPE }; 
    } 
} 

но не дает ошибку как :::

Answer 1

Hibernate не поддерживает database arrays (например java.sql.Array)

array и primitive-array типов, предоставляемых Hibernate предназначены для отображения Java массивов в бэк-таблицу - они в основном изменение сопоставлений «один ко многим»/набор элементов.

Здесь example для Postgresql, в котором @Alex разобрал эту проблему самостоятельно, используя UserType for integer arrays. Кроме того, этот example связан с отображением массива postgres с гибернацией.
Надеюсь, это поможет.
