Question

我在Spring Boot中使用Hibernate搜索。我在application.properties文件中使用以下属性指定索引位置。

spring.jpa.properties.hibernate.search.default.directory_provider: filesystem
spring.jpa.properties.hibernate.search.default.indexBase: /opt/indexes/lucene/

我的POM文件具有以下依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-search-orm</artifactId>
    <version>4.5.1.Final</version>
</dependency>

<!-- Optional: to use JPA 2.1 -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
</dependency>

我还有一个ApplicationListener，可以在重新加载上下文时构建索引。

@SuppressWarnings("rawtypes")
@Component
public class BuildSearchIndex implements ApplicationListener {

    private static final Log LOG = LogFactory.getLog(BuildSearchIndex.class);

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void onApplicationEvent(ApplicationEvent event) {

        if (event instanceof ContextRefreshedEvent) {
            try {
                FullTextEntityManager fullTextEntityManager =        Search.getFullTextEntityManager(entityManager);
            fullTextEntityManager.createIndexer().startAndWait();
        } catch (InterruptedException e) {
            LOG.error("InterruptedException while trying to index entities for search", e);
        }
    }
    return;
}
}

我遇到的问题是，当应用程序启动时，索引是在指定位置创建的，但是加载失败并显示下面的堆栈跟踪：

我无法弄清楚应用程序试图访问/的原因。目录。还有其他人遇到过类似的问题吗？
