Hibernate无法确定方言(Hibernate cannot determine dialect)

我正在使用hibernate 4.3.x连接到oracle数据库。

但是在创建映射文件时它会抛出

“无法确定要使用的方言[name = Oracle，majorVersion = 12] ......”

这应该是hiberante 3.x中的问题（根据谷歌）

我怎样才能解决这个问题？谢谢

配置属性：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property> <property name="hibernate.connection.url">jdbc:oracle:...</property> <property name="hibernate.connection.username">name</property> <property name="hibernate.connection.password">Passwd</property> <mapping class="Nemocnica" package="Model"/> </session-factory> </hibernate-configuration>

I am using hibernate 4.3.x to connect to oracle database.

However while creating mapping file it throws

"Unable to determine Dialect to use [ name = Oracle , majorVersion = 12 ]..."

which should be problem ( according to google ) in hiberante 3.x

How can i fix this? Thanks
