未指定hibernate.search.lucene_version：

Question

我在Spring Boot中使用Hibernate Search。我没有对Hibernate Search进行任何特殊配置。它仅显示应用程序启动时的警告。如何指定hibernate.search.lucene_version？我的SearchService类（使用Hibernate Search的唯一位置）：@Servicepublic class SearchService {    private FullTextEntityManager fullTextEntityManager;    private QueryBuilder queryBuilder;    @Autowired    public SearchService(EntityManager entityManager) {        entityManager = entityManager.getEntityManagerFactory().createEntityManager();        fullTextEntityManager = Search.getFullTextEntityManager(entityManager);    }    @PostConstruct    public void initialize() throws InterruptedException {        fullTextEntityManager.createIndexer().startAndWait();        queryBuilder = fullTextEntityManager.getSearchFactory()                .buildQueryBuilder().forEntity(Post.class).get();    }    public List<Post> searchByQuery(String query) {        org.apache.lucene.search.Query luceneQuery = queryBuilder.phrase()                .withSlop(5)                .onField("title")                .sentence(query)                .createQuery();        Query jpaQuery = fullTextEntityManager.createFullTextQuery(luceneQuery, Post.class);        return (List<Post>) jpaQuery.setMaxResults(20).getResultList();    }}
