Hibernate搜索索引未完成的文档

我在批量编制数据索引时遇到问题。 我想为一个

文章

列表编制索引，并在需要获取信息的成员上添加一些

@IndexedEmbedded

Article

从另外两个bean获取附加信息：

Page

和

Articlefulltext

由于Hibernate搜索注释，批处理正在正确更新数据库，并将新的

文档添加到我的Lucene索引中。但是添加的文档有不完整的字段。Hibernate搜索似乎没有看到所有的注释

因此，感谢Luke，当我查看生成的lucene索引时，我有一些关于Article和Page对象的字段，但没有关于ArticleFulltext的字段，但我的数据库中有正确的数据，这意味着persist（）操作已正确完成

我真的需要一些帮助，因为我看不出我的页面和文章全文之间有什么区别

奇怪的是，如果我使用
MassIndexer
，它会正确地将Article+Page+Article全文数据添加到lucene索引中。但我不想每次做一个大的更新时都重建数百万个文档索引

对于hibernate搜索和lucene，我将log4j日志记录级别设置为debug。他们没有给我那么多信息

这是我的bean代码和批处理代码

提前感谢您的帮助

下面是用于更新数据库和Lucene索引的代码

嗯，你似乎并没有把双方的关系都确定下来。我可以看到ft.setArticle（article），但看不到article.setFtArticle（ft）。关系的两个方面都需要设置。在您的情况下，Articlefulltext是关系的所有者，但这意味着您不必设置双方
 嗯，你说得对，非常感谢你。。。太简单了。奇怪的是，对于Page，我只创建了关系的一面，但它工作正常。这是因为它是一个多通关系吗？这取决于我们必须遍历关系链接的哪个方向来更新索引。很可能页面的内容是在主方向（仅）填写的，因此是偶然的。“偶然的”，所以“最佳”实践是定义双方的所有关系？很高兴知道，它在任何地方都能做到。谢谢你们两个！您不必将所有关系都定义为双向关系，但如果您定义为双向关系，则必须同时更新双方，否则会混淆哪个实例提供了正确的信息。搜索可能需要将关系定义为双向关系，以允许一个位置同时定义IndexedEmbedded和ContainedIn
