我正在尝试将Hibernate Search的Elasticsearch实现添加到现有项目中。
一切似乎都还好，我的更新实体和新实体都已索引到Elastic，但是当我尝试将现有数据索引到Elasticsearch中(使用文档中提供的片段)时，出现了错误，整个应用程序崩溃了。
索引代码
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(JPA.em());
fullTextEntityManager.createIndexer().startAndWait();

任何想法如何索引初始数据而不会出现此错误？
谢谢 !
最佳答案
我认为您缺少通过查询插件删除的信息:https://www.elastic.co/guide/en/elasticsearch/plugins/2.4/plugins-delete-by-query.html
有关如何配置Elasticsearch集群的信息，请参阅我们的文档中的本段:http://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#_elasticsearch_configuration。
请注意，该插件已集成到Elasticsearch 5中，但我们尚不支持Elasticsearch 5。
关于hibernate - 带有Elasticsearch的Hibernate Search中的初始索引崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41940996/
