犯得很大的问题

1. 错误
   在请求是报错bitsum在请求提交按钮时 将按钮误用成submit 导致数据提交后就刷新界面 数据还没有被读取到 就结束了api访问导致的bug
   报错 http请求显示为cancel
   
2. 完善后的关于读取jd数据的service层

public List<Map<String ,Object>> SreachPag(String keywork , int PagNo, int PagSize) throws IOException {


        if (PagNo <= 1) {
            PagNo = 1;
        }
        //条件搜索
        SearchRequest searchRequest = new SearchRequest("jd_goods");
        SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
        //分页
        sourceBuilder.from(PagNo);
        sourceBuilder.size(PagSize);
        //精准匹配
//        TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery("title", keyword);
//        sourceBuilder.query(termQueryBuilder);
//        sourceBuilder.timeout(new TimeValue(60, TimeUnit.SECONDS));

        //match匹配 可以支持中文搜索
        MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("title", keywork);
        sourceBuilder.query(matchQueryBuilder);
        sourceBuilder.timeout(new TimeValue(60, TimeUnit.SECONDS));//超时
        //高亮
        HighlightBuilder highlightBuilder = new HighlightBuilder();
        highlightBuilder.field("title"); //高亮的字段
        highlightBuilder.requireFieldMatch(false);//如果一句里面有多个关键词高亮，则只显示第一个
        highlightBuilder.preTags("<span style='color:red'>");
        highlightBuilder.postTags("</span>");
        sourceBuilder.highlighter(highlightBuilder);
        //执行搜索
        searchRequest.source(sourceBuilder);
        SearchResponse searchResponse = estHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
        //解析结果
        ArrayList<Map<String, Object>> list = new ArrayList<>();
        for (SearchHit hit : searchResponse.getHits().getHits()) {

            Map<String, HighlightField> highlightFields = hit.getHighlightFields(); //获取到高亮字段
            HighlightField title = highlightFields.get("title");
            Map<String, Object> sourceAsMap = hit.getSourceAsMap(); //原来的结果！要在结果里面将高亮置换一下
            //解析高亮的字段 将原来的字段换为我们高亮的字段即可
            if (title != null) {
                Text[] fragments = title.fragments();
                String n_title = "";
                for (Text text : fragments) {
                    n_title += text;
                }
                sourceAsMap.put("title", n_title);//高亮字段替换掉原来的内容即可！
            }
            list.add(sourceAsMap);
        }
        return list;
    }

3. config配置

@Configuration
public class ESConfig {

    @Bean
    public RestHighLevelClient estHighLevelClient (){
        RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost(Name.IP,Name.PROT,Name.SECHENM)
                )
        );


        return restHighLevelClient;
    }


}
