使用solr实现京东网站中的商品搜索功能，
需求：
1.可以根据关键字搜索商品信息
2.可以根据商品分类、价格过滤搜索结果
3.可以根据价格排序
4.可以实现分页
源码及solrHome下载地址：csdn站内下载
界面如下：
Controller层：获取搜索条件，响应搜索结果到前台页面
service层：使用solrj调用solr的服务进行索引和搜索
dao层：不开发（数据参考solr笔记（二））
1.配置商品图片的虚拟目录 images
我们先来分析一下product_list.jsp

创建pojo
页面需要什么就传递什么，根据分析简历商品的pojo，pid name price picture
public class Product { private String pid; private String name; private String price; private String picture; get/set。。。 } 创建分页结果pojo public class Result { private Integer curPage;// 当前页 private Integer pageCount;// 总页数 private Long recordCount;// 数据总条数 private List<Product> productList;// 商品结果集 get/set。。。 } service public interface SearchService { /** * 根据条件从索引库中查询数据 * * @param queryString 查询关键词 * @param catalog_name 商品分类 * @param price 商品价格 * @param sort 排序 * @param page 当前页码 * @return */ Result search(String queryString, String catalog_name, String price, String sort, Integer page);}
@Service public class SearchServiceImpl implements SearchService { @Autowired private HttpSolrServer httpSolrServer; @Override public Result search(String queryString, String catalog_name, String price, String sort, Integer page) { // 创建SolrQuery对象 SolrQuery solrQuery = new SolrQuery(); // 设置查询关键词 if (StringUtils.isNotBlank(queryString)) { solrQuery.setQuery(queryString); } else { solrQuery.setQuery("*:*"); } // 设置默认域 solrQuery.set("df", "product_keywords"); // 设置商品类名过滤条件 // 设置商品分类名称 if (StringUtils.isNotBlank(catalog_name)) { catalog_name = "product_catalog_name:" + catalog_name; } // 设置商品价格 if (StringUtils.isNotBlank(price)) { String[] sp = price.split("-"); if (sp != null && sp.length == 2) { price = "product_price:[" + sp[0] + " TO " + sp[1] + "]"; } } solrQuery.setFilterQueries(catalog_name, price); // 商品排序，如果是1，正序排序，如果是其他，则倒序排序 if ("1".equals(sort)) { solrQuery.setSort("product_price", ORDER.asc); } else { solrQuery.setSort("product_price", ORDER.desc); } // 设置分页 if (page == null) { page = 1; } solrQuery.setStart((page - 1) * 20); solrQuery.setRows(20); // 设置高亮 solrQuery.setHighlight(true); solrQuery.addHighlightField("product_name"); solrQuery.setHighlightSimplePre("<font color='red'>"); solrQuery.setHighlightSimplePost("</font>"); // 查询数据 QueryResponse response; try { response = httpSolrServer.query(solrQuery); // 获取查询总数 SolrDocumentList results = response.getResults(); long total = results.getNumFound(); // 获取高亮数据 Map<String, Map<String, List<String>>> map = response.getHighlighting(); // 解析结果集，存放到Product中 List<Product> products = new ArrayList<>(); for (SolrDocument solrDocument : results) { Product product = new Product(); // 商品id product.setPid(solrDocument.get("id").toString()); // 商品标题，设置高亮 List<String> list = map.get(solrDocument.get("id")).get("product_name"); if (list != null && list.size() > 0) { product.setName(list.get(0)); } else { product.setName(solrDocument.get("product_name").toString()); } // 商品价格 product.setPrice(solrDocument.get("product_price").toString()); // 商品图片 product.setPicture(solrDocument.get("product_picture").toString()); products.add(product); } // 封装返回对象 Result result = new Result(); result.setCurPage(page); result.setRecordCount(total); result.setProductList(products); // 总页数计算公式(total+rows-1)/rows result.setPageCount((int) (total + 20 - 1) / 20); return result; } catch (SolrServerException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; }controller
