024/**
025 * Hibernate3 interceptor used for getting the proper entity name for scoped
026 * beans. As scoped bean classes are proxies generated at runtime, they are
027 * unrecognized by the persisting framework. Using this interceptor, the
028 * original scoped bean class is retrieved end exposed to Hibernate for
029 * persisting.
030 *
031 * <p>Usage example:
032 *
033 * <pre class="code">
034 * &lt;bean id=&quot;sessionFactory&quot; class=&quot;org.springframework.orm.hibernate3.LocalSessionFactoryBean&quot;&gt;
035 *   ...
036 *   &lt;property name=&quot;entityInterceptor&quot;&gt;
037 *     &lt;bean class=&quot;org.springframework.orm.hibernate3.support.ScopedBeanInterceptor&quot;/&gt;
038 *   &lt;/property&gt;
