package com.gstone.history.entity;

import java.sql.Types;

import org.hibernate.Hibernate; import org.hibernate.dialect.MySQLDialect;

public class BlobMySQLDialect extends MySQLDialect{  public BlobMySQLDialect(){   super();    registerHibernateType(Types.LONGVARBINARY, Hibernate.BLOB.getName());  } }

然后在配置文件中，改方言：

 <prop key="hibernate.dialect">

     com.gstone.history.entity.BlobMySQLDialect

 </prop>

 

 

 

<bean id="sessionFactory"

  class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

  <property name="dataSource" ref="dataSource"></property>

  <property name="packagesToScan" value="com.gstone"/>

  <property name="hibernateProperties">

   <props>

    <prop key="hibernate.show_sql">false</prop>

    <prop key="hibernate.dialect">

     com.gstone.history.entity.BlobMySQLDialect

    </prop>

    <prop key="hibernate.cache.provider_class">

     org.hibernate.cache.EhCacheProvider

    </prop>

    <prop key="hibernate.cache.provider_configuration_file_resource_path">

     spring/ehcache.xml

    </prop>

   </props>

  </property>

 </bean>
