Question

我目前正在大学撰写论文，主题是将搜索功能集成到现有的Web应用程序中，并希望使用Hibernate Search。

但我正在努力解决现有应用程序中的实体索引问题。似乎索引不起作用，因为在创建新实体时不会生成索引文件。此外，当我启动应用程序时，不会创建在休眠配置中配置的基本索引目录。该应用程序将Spring Framework和Hibernate Core与hibernate-jpa 2.0一起使用（参见pom.xml）。

执行应用程序时没有错误，但有关于Hibernate Search的信息

 INFO AnnotationSessionFactoryBean:780 - Building new Hibernate SessionFactory
 INFO HibernateSearchEventListenerRegister:75 - Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath. Hibernate Search is not enabled.

我读到在使用hibernate注释时我不需要集成这些监听器，所以这不能成为问题的根源，对吧？
