Question

根据文档http://docs.spring.io/spring-framework/docs/3.2.2.RELEASE/spring-framework-reference/html/beans.html#beans-factory-lazy-init，以下内容不应该是MyDatabase，但我可以清楚地看到调试afterPropertiesSet类的HibernateDatabase方法时就是这种情况。如果我删除MyDatabaseEntityManagerFactory，则不会发生这种情况。但是，考虑到MyDatabaseEntityManagerFactory也是懒惰的，这应该不重要 - 它不应该导致MyDatabase初始化。

要么我误解了文档中那些说引用另一个懒豆的懒惰的bean不应该导致它初始化或者Spring中存在根本问题的部分。任何人都可以对此有所了解，或者可能建议替代我想达到的目标吗？

感谢。

    <bean id="MyDatabaseEntityManagerFactory" parent="EntityManagerFactory" lazy-init="true">

lazy-init实际上是否像宣传的那样工作？
