elasticsearch高亮顯示查詢結果

//高亮顯示查詢結果 @Test public void demo9() throws Exception{//創建連接搜索服務器的對象Client client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9300));ObjectMapper objectMapper = new ObjectMapper();//搜索 數據SearchRequestBuilder searchRequestBuilder = client.prepareSearch("blog2").setTypes("article").setQuery(QueryBuilders.termQuery("title","搜索 "));//高亮定義searchRequestBuilder.addHighlightedField("title");//對title字段進行高亮顯示searchRequestBuilder.setHighlighterPreTags("<em>");//前置元素searchRequestBuilder.setHighlighterPostTags("</em>");//后置元素SearchResponse searchResponse = searchRequestBuilder.get();SearchHits hits = searchResponse.getHits();//獲取命中次數，查詢結果有多少對象System.out.println("查詢結果有："+hits.getTotalHits()+"條");Iterator<SearchHit> iterator = hits.iterator();while(iterator.hasNext()){SearchHit searchHit = iterator.next();//每個查詢對象//將高亮處理后的內容，替換原有內容（原有內容，可能會出現顯示不全）Map<String,HighlightField> hightlightFields = searchHit.getHighlightFields();HighlightField titleField = hightlightFields.get("title");//獲取到原有內容中 每個高亮顯示 集中位置fragment就是高亮片段Text[] fragments = titleField.fragments();String title = "";for(Text text:fragments){title += text;}//將查詢結果轉換為對象Article article = objectMapper.readValue(searchHit.getSourceAsString(),Article.class);//用高亮后的內容，替換原有內容article.setTitle(title);System.out.println(article);}//關閉連接client.close(); }
