Examples with FullTextSession org.hibernate.search.FullTextSession used on opensource projects

Example 1 with FullTextSession

use of org.hibernate.search.FullTextSession in project nikita-noark5-core by HiOA-ABI.

the class FondsHateoasController method findAllFonds.

// Find all fonds using elasticsearch ... This is experimental and not part of the standard
// No swagger documentation on this. If we decide to drop db for es, then all re
// GET [contextPath][api]/arkivstruktur/arkiv/all/
@RequestMapping(method = RequestMethod.GET, value = FONDS + SLASH + "all" + SLASH)
public ResponseEntity<FondsHateoas> findAllFonds(final UriComponentsBuilder uriBuilder, HttpServletRequest request, final HttpServletResponse response, @RequestParam(name = "filter", required = false) String filter) {
    Session session = entityManager.unwrap(Session.class);
    FullTextSession fullTextSession = Search.getFullTextSession(session);
    QueryDescriptor query = ElasticsearchQueries.fromQueryString("title:test fonds");
    List<Fonds> result = fullTextSession.createFullTextQuery(query, Fonds.class).list();
    FondsHateoas fondsHateoas = new FondsHateoas((ArrayList<INikitaEntity>) (ArrayList) result);
    fondsHateoasHandler.addLinks(fondsHateoas, request, new Authorisation());
    return ResponseEntity.status(HttpStatus.OK).allow(CommonUtils.WebUtils.getMethodsForRequestOrThrow(request.getServletPath())).body(fondsHateoas);
}

Example 2 with FullTextSession

use of org.hibernate.search.FullTextSession in project weicoder by wdcode.

the class HibernateSearch method search.

/**
 * 使用索引查询
 * @param session Hibernate Session
 * @param entity 实体
 * @param firstResult 重第几条开始查询
 * @param maxResults 一共查回多少条
 * @param <E> 泛型
 * @return 数据列表
 */
@SuppressWarnings("unchecked")
public <E> List<E> search(Session session, E entity, int firstResult, int maxResults) {
    // 通过Hibernate的Session获取FullTextSession对象
    FullTextSession fullTextSession = Search.getFullTextSession(session);
    // 获取特定类的特定QueryBuilder对象
    QueryBuilder queryBuilder = fullTextSession.getSearchFactory().buildQueryBuilder().forEntity(entity.getClass()).get();
    // 得到search query
    org.apache.lucene.search.Query query = queryBuilder.all().createQuery();
    // 这里使用FullTextQuery和org.hibernate.Query来分装org.apache.lucene.search.Query都是可以的，
    // 但FullTextQuery的功能比org.hibernate.Query的功能要强大一点，究竟什么时候要用org.hibernate.Query而不能用
    // org.apache.lucene.search.Query这个我暂时还没有发现！
    FullTextQuery fullTextQuery = fullTextSession.createFullTextQuery(query, entity.getClass()).setCriteriaQuery(DetachedCriteria.forClass(entity.getClass()).getExecutableCriteria(fullTextSession).add(Example.create(entity)));
    // 开始结果大于等于0
    if (firstResult >= 0) {
        fullTextQuery.setFirstResult(firstResult);
    }
    // 最大结果大于零
    if (maxResults > 0) {
        fullTextQuery.setMaxResults(maxResults);
    }
    // 返回结果
    return fullTextQuery.list();
}
