主要讲解Solrj的使用【查询】
//新建一个solr服务 HttpSolrServersolrServer=newHttpSolrServer("http://localhost:8983/solr/collection1"); //新建一个solr查询对象 SolrQuerysq=newSolrQuery(); //设置查询条件 //--设置查询条件 sq.setQuery("*:*"); //--设置默认查询域 sq.set("df","product_keywords"); //--设置过滤条件 sq.filterQueryies("product_catalog_name:衣服","product_price:[20TO50]"); //--设置分页条件 sq.setStart(0);//从第几条记录开始 sq.setRows(10);//页最大容量 //--设置查询结果排序 sq.setSort("product_price",ORDER.asc); //设置高亮 //--开启高亮显示 sq.setHighlight(true); //--设置高亮显示字段 sq.setHighlightField("product_name"); //--设置高亮标签 sq.setHighlightSimplePre("<fontcolor=‘red‘>"); sq.setHighlightSimplePost("</font>"); //查询，获得响应对象 QueryResponseqr=solrServer.query(sq); //获取查询结果集合 SolrDocumentListresultList=qr.getResults(); //获取高亮字段集合 Map<Stirng,Map<String,List<String>>>highlighting=qr.getHighlighting(); //封装查询结果 List<Porduct>productList=newArrayList<>(); for(SolrDocumentdoc:SolrDocumentList){ //获取id域 Stringid=doc.get("id").toString(); //获取名称域 Stringname=null; List<String>list=highlighting.get(id).get("product_name"); if(list!=null&&list.size>0){ name=list.get(0); }else{ name=doc.get("name").toString(); } //获取其他域 Stringprice=doc.get("price").toString(); Stringpicture=doc.get("picture").toString; //封装 Productp=newProduct(); p.setId(id); p.setName(name); p.setPrice(price); p.setPicture(picture); productList.add(p); }
