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">
