为什么我的应用程序无法启动（使用休眠搜索配置）？

Question

我想使用 Hibernate Search 对 JPA 实体进行全文搜索。我已经配置了：

# Specify the DirectoryProvider to use (the Lucene Directory)
spring.jpa.properties.hibernate.search.default.directory_provider = filesystem

# Using the filesystem DirectoryProvider you also have to specify the default
# base directory for all indexes (make sure that the application have write
# permissions on such directory)
spring.jpa.properties.hibernate.search.default.indexBase = /var/lucene/indexes/data

我手动创建了目录 /var/lucene/indexes/data 并授予数据目录 777 权限

当我启动我的应用程序时，出现以下错误：
