我在批量索引数据时遇到了问题。我想要对一些成员使用
批量会通过Hibernate Search Annotations正确更新数据库并添加新的
因此,当我查看Lucene Index时,可以看到关于Article和Page对象的某些字段,但没有关于ArticleFulltext的任何字段,但我的数据库中有正确的数据,这意味着persist()操作已正确执行...
我真的需要一些帮助,因为我不知道Page和ArticleFullText之间有什么区别...
奇怪的是,如果我使用
我将log4j日志级别设置为hibernate search和lucene的debug级别。他们没有给我太多信息。
以下是我的bean代码和批处理代码。
感谢您的帮助,
Article.java:
@IndexedEmbedded
,并且需要获取信息的Article
列表进行索引。文章从另外两个bean:Page和Articlefulltext中获取附加信息。批量会通过Hibernate Search Annotations正确更新数据库并添加新的
Document
到我的Lucene索引。但是添加的文档具有不完整的字段。似乎Hibernate Search没有看到所有的注解。因此,当我查看Lucene Index时,可以看到关于Article和Page对象的某些字段,但没有关于ArticleFulltext的任何字段,但我的数据库中有正确的数据,这意味着persist()操作已正确执行...
我真的需要一些帮助,因为我不知道Page和ArticleFullText之间有什么区别...
奇怪的是,如果我使用
MassIndexer
,它将正确地将Article + Page + Articlefulltext数据添加到Lucene索引中。但我不想每次进行大型更新时都重建数百万条文档索引...我将log4j日志级别设置为hibernate search和lucene的debug级别。他们没有给我太多信息。
以下是我的bean代码和批处理代码。
感谢您的帮助,

以下是用于更新数据库和Lucene索引的代码:
批处理源代码:
FullTextEntityManager em = null;
@Override
protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
ApplicationContext ap = null;
EntityManagerFactory emf = null;
EntityTransaction tx = null;
try {
ap = (ApplicationContext) arg0.getScheduler().getContext().get("applicationContext");
emf = (EntityManagerFactory) ap.getBean("entityManagerFactory", EntityManagerFactory.class);
em = Search.getFullTextEntityManager(emf.createEntityManager());
tx = em.getTransaction();
tx.begin();
// [... em.persist() some things which aren't lucene related, so i skip them ....]
for(File xmlFile : xmlList){
Reel reel = new Reel(title, reelpath);
em.persist(reel);
Article article = new Article();
// [... set Article fields, so i skip them ....]
Articlefulltext ft = new Articlefulltext();
// [... set Articlefulltext fields, so i skip them ....]
ft.setArticle(article);
ft.setFulltextcontents(bufferBlock.toString());
em.persist(ft); // i persist ft before article because of FK issues
em.persist(article); // there, the Annotation update Lucene index, but there's not updating fultextContent (see my first post)
if ( nbFileDone % 50 == 0 ) {
//flush a batch of inserts and release memory:
em.flush();

}
}
tx.commit();
}
catch(Exception e){
tx.rollback();

em.close();
