org.hibernate.MappingException: No Dialect mapping for JDBC type: -9
查阅资料，这个是由于JAVA对应数据库类型映射问题，-9是NVARCHAR 类型映射不了，
根据自己的方言加上：

public class SqlServer2008Dialect extends MySQL5Dialect{
public SqlServer2008Dialect(){
super();
registerHibernateType(Types.DECIMAL, Hibernate.BIG_DECIMAL.getName());
registerHibernateType(-1, Hibernate.STRING.getName());
}
}
在属性文件配置：
<property name="hibernate.dialect" value="XXXXX(自己的包名.SqlServer2008Dialect)" />
就行了。
