我在批量索引数据时遇到问题。我想索引一个Article列表，其中包含一些@IndexedEmbedded我需要获取信息的成员。Article从另外两个 bean 获取附加信息：Page和Articlefulltext.
由于 Hibernate Search Annotations，该批次正在正确更新数据库并为我的 Lucene 索引添加新内容。Document但添加的文档字段不完整。似乎 Hibernate Search 没有看到所有的注释。
因此，当我通过 Luke 查看生成的 lucene Index 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 Page 和 ArticleFullText 之间有什么区别......
奇怪的是，如果我使用 a MassIndexer，它会正确地将 Article + Page + Articlefulltext 数据添加到 lucene 索引中。但是我不想每次进行重大更新时都重建数百万个文档索引...
我将 log4j 日志记录级别设置为调试休眠搜索和 lucene。他们没有给我太多信息。
这是我的 bean 代码和批处理代码。
在此先感谢您的帮助，

@Field(store=Store.YES, index=Index.YES, analyzer = @Analyzer(impl = FrenchAnalyzer.class), bridge= @FieldBridge(impl = FulltextSplitBridge.class))
// This Field is not add to the Resulting Document ! I put a log into FulltextSplitBridge, and it's never called during a batch process. But if I use a MassIndexer, i see that FulltextSplitBridge is called for each Articlefulltext ...
private String fulltextcontents;
[... bean method ...]
这是用于更新数据库和 Lucene 索引的代码
批处理源代码：
