mysql方言不支持blob类型解决方案

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>
