我正在使用Hibernate搜索orm（最终版5.5.4）和lucene（最终版5.5.4）进行索引。
正常启动服务器时，一切正常，但是重新启动服务器时，出现此错误。

我已更改目录的权限，并已授予该用户写权限。
答案 0 :(得分：0)
您很可能忘记了设置索引的根目录，而Hibernate Search默认将索引存储在JVM的工作目录中（无论它是什么）。
将属性hibernate.search.default.indexBase设置为您知道应用程序将具有写访问权限的目录，并且该目录应该消失。有关配置目录的更多信息，请参见https://docs.jboss.org/hibernate/search/5.11/reference/en-US/html_single/#search-configuration-directory。
关于它第一次起作用的事实……我想第一次有什么不同。也许Hibernate Search已被禁用，或者您是从另一个目录启动了该应用程序？无论如何，真正的问题很可能与访问权限有关。
