老哥们，springdata整合es，怎么用高亮字段替换原有字段。问题如图。博客上都是比较老的版本，新版以后删掉了很多api不会整了

boot是2.5x的版本，返回的searchhit没有很多博客上写的getsourceasmap的方法

而且返回高亮属性方法里也没有HighlightField类了，替换成了字符串列表了

顶一下

dd

public List<Map<String,Object>> searchPageHighlight(String keyword,int pageNo,int size) throws IOException {
if (pageNo<=1){
pageNo = 1;
}
if (size<=1){
size = 10;
}
SearchRequest request = new SearchRequest(indexName);
TermQueryBuilder matchQueryBuilder = QueryBuilders.termQuery("title", keyword);
//高亮
HighlightBuilder highlightBuilder = new HighlightBuilder();
highlightBuilder.field("title").preTags("<span style='color:red'>").postTags("</span>");
// highlightBuilder.requireFieldMatch(false); // 关闭多个高亮显示
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(matchQueryBuilder)
.timeout(TimeValue.timeValueSeconds(3))
.from(pageNo)
.size(size)
.highlighter(highlightBuilder);
//执行搜索
request.source(searchSourceBuilder);
SearchResponse response = restHighLevelClient.search(request, RequestOptions.DEFAULT);
//分析结果
List<Map<String,Object>> list = new ArrayList<>();
for (SearchHit hit : response.getHits()) {
// 解析高亮字段
Map<String, HighlightField> highlightFields = hit.getHighlightFields();
HighlightField title = highlightFields.get("title");
Map<String, Object> sourceAsMap = hit.getSourceAsMap();
if (title != null){
// 将原来的字段 换位新的高亮字段
Text[] fragments = title.getFragments();
String newTitle = "";
for (Text fragment : fragments) {
newTitle+=fragment;
}
sourceAsMap.put("title",newTitle); // 替换原先的字段
}
list.add(sourceAsMap);
}
return list;
}
