Hibernate的继承映射
对象模型示例： 继承映射的实现方式有以下三种： （一）每棵类继承树一张表 （二）每个类一张表 （三）每个子类一张表 （一）每棵类继承树一张表 关系模型如下： 映射文件如下： <hibernate-mapping discriminator-value="B"> <property name="height"/> </subclass> </class> </hibernate-mapping 关于鉴别值在存储的时候hibernate会自动存储，在加载的时候会根据鉴别值取得相关的对象 （二）每个类一张表 关系模型如下： 映射文件如下： <hibernate-mapping package="com.nnngu column="bid"/> <property name="height"/> </joined-subclass> </class> </hibernate-mapping （三）每个子类一张表 关系模型如下： 映射文件如下： <hibernate-mapping package="com.nnngu"> <class name="Animal" table="
