但是Hibernate反向工程创建的代码没有任何@entity、@table或@column标记看起来所有的映射都在hbm.xml中。如何在Spring MVC项目中使用它们

Answer 1

您可以使用hbm.xml文件，将其包含在applicationContext中并在项目中使用。唯一的区别是所有映射都将出现在hbm文件中。在代码中使用它们作为注释。

您的应用程序上下文应该如下所示：

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="mappingResources">
            <list>
                          <!-- All your hbms --><value>yourHbmFile.hbm.xml</value>

            </list>
        </property>
..
.
</bean>

此外，如果您想映射包含您可以使用的所有HBM的目录：

<property name="mappingDirectoryLocations" value="classpath:org/../hibernate/model" />
