org.hibernate.MappingException: No Dialect mapping for JDBC type: -1 搞定！

继承于MySQLDialect ，引入 registerHibernateType(Types.LONGVARCHAR, Hibernate.TEXT.getName());

import java.sql.Types;

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

public class ThisMySQLDialect extends MySQLDialect {
public ThisMySQLDialect (){
super();
registerHibernateType(Types.LONGVARCHAR, Hibernate.TEXT.getName());
}

}

hibernate 配置修改

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="connection.useUnicode">true</prop>
<prop key="connection.characterEncoding">GBK</prop>
<prop key="hibernate.dialect">com.yjf.dao.ThisMySQLDialect </prop><!-- org.hibernate.dialect.Oracle9Dialect -->
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">false</prop>
<!-- <prop key="hibernate.hbm2ddl.auto">update</prop> -->
<prop key="hibernate.jdbc.batch_size">0</prop>
</props>
</property>
<property name="mappingLocations">
