Spring整合Solr

Spring配置：

Java代码操作Solr索引库：

package cn.xing.test;import java.util.ArrayList;import java.util.List;import java.util.Map;import org.apache.solr.client.solrj.SolrQuery;import org.apache.solr.client.solrj.SolrServer;import org.apache.solr.client.solrj.SolrServerException;import org.apache.solr.client.solrj.response.QueryResponse;import org.apache.solr.common.SolrDocument;import org.apache.solr.common.SolrDocumentList;import org.apache.solr.common.SolrInputDocument;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import cn.xing.pojo.SearchItem;import cn.xing.pojo.SearchResult;/** * 操作solr索引库 *  * @author Xing * */@Servicepublic class Operation {        @Autowired        private SolrServer solrServer;// 是配置的httpSolrServer        /**         * 把所有商品导入索引库，商品对象SearchItem必须和solr配置的业务域字段、类型相同         */        public void imprtSolrItem() {                try {                        List list = new ArrayList();                        list.add(new SearchItem("1", "湖北", "黄鹤楼", 12, "image1", "省市"));                        list.add(new SearchItem("2", "河南", "开封", 12, "image2", "省市"));                        list.add(new SearchItem("3", "3", "3", 12, "image2", "222"));                        // 把list放入索引库                        for (SearchItem searchItem : list) {                                SolrInputDocument doc = new SolrInputDocument();                                doc.addField("id", searchItem.getId());                                doc.addField("item_title", searchItem.getTitle());                                doc.addField("item_sell_point", searchItem.getSell_point());                                doc.addField("item_price", searchItem.getPrice());

                       }                        solrServer.commit();                        System.out.println("数据导入成功");                } catch (Exception e) {                        e.printStackTrace();                }        }        // 根据查询条件SolrQuery,查询索引库        public List querySolr(SolrQuery query) throws SolrServerException {                // 根据条件查询索引库                QueryResponse queryResponse = solrServer.query(query);                SolrDocumentList results = queryResponse.getResults();                // 取出总记录数                long num = results.getNumFound();                System.out.println("查询结果的数据条数：" + num);                // 取出商品列表,高亮关键词                // Map<商品id,Map<商品属性字段,List<字段的值>>>                Map>> highlighting = queryResponse.getHighlighting();                List itemList = new ArrayList<>();                for (SolrDocument solrDocument : results) {                        SearchItem item = new SearchItem();                        item.setId((String) solrDocument.get("id"));                        item.setCategory_name((String) solrDocument.get("item_category_name"));                        item.setImage((String) solrDocument.get("item_image"));                        item.setPrice((long) solrDocument.get("item_price"));                        item.setSell_point((String) solrDocument.get("item_sell_point"));                        // 取高亮结果，商品标题                        List list = highlighting.get(solrDocument.get("id")).get("item_title");                        if (list != null && list.size() > 0) {                                item.setTitle(list.get(0));// 拿到该商品标题                        } else {                                item.setTitle((String) solrDocument.get("item_title"));                        }                        itemList.add(item);                }                return itemList;        }        /**         * 根据关键词在solr索引库中搜索商品并分页。         */        public SearchResult search(String keyword, int page, int rows) throws Exception {                // 设置查询条件，调用querySolr()方法查询                SolrQuery query = new SolrQuery();                query.setQuery(keyword);// 设置查询条件                if (page <= 0)                        page = 1;                query.setStart((page - 1) * rows);// 设置分页索引                query.setRows(rows);// 设置查询条数                // 设置默认搜索域                query.set("df", "item_title");

               // 执行查询                List itemList = this.querySolr(query);                // 设置返回结果                SearchResult rs = new SearchResult();                rs.setItemList(itemList);                /*                 * // 设置总页数 int totalpages = rs.getRecourdCount() / rows; if                 * (rs.getRecourdCount() % rows > 0) totalpages++; rs.setTotalPages((long)                 * totalpages);                 */                                return rs;        }}

分页查询数据封装：

package cn.xing.pojo;import java.io.Serializable;import java.util.List;/** * 搜素商品的结果。对页面需要的数据的封装。 *  * @author Xing * */public class SearchResult implements Serializable {        private Long totalPages;        private Integer recourdCount;        private List itemList;}

Solr数据对应的pojo：

package cn.xing.pojo;import java.io.Serializable;import org.apache.commons.lang3.StringUtils;public class SearchItem implements Serializable {        @Override        public String toString() {                return "SearchItem [id=" + id + ", title=" + title + ", sell_point=" + sell_point + ", price=" + price                                + ", image=" + image + ", category_name=" + category_name + "]";        }        // 类型和solr的中文分析器里的schema.xml中配置的type必须一样        private String id;        private String title;        private String sell_point;        private long price;        private String image;        private String category_name;        // 搜索结果页面展示一张图片        public String[] getImages() {                String image2 = this.getImage();                if (StringUtils.isNotBlank(image2)) {                        String[] imagesArr = image2.split(",");                        return imagesArr;                }                return null;        }        public String getId() {                return id;        }        public void setId(String id) {                this.id = id;        }}

Java测试代码：

package cn.xing.test;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.xing.pojo.SearchItem;import cn.xing.pojo.SearchResult;public class test {        public static void main(String[] args) throws Exception {                ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");                Operation operation = ac.getBean(Operation.class);                // 导入数据                operation.imprtSolrItem();//              SearchResult search = operation.search("明明就", 1, 1);                SearchResult search = operation.search("3", 1, 10);                List itemList = search.getItemList();                for (SearchItem searchItem : itemList) {                        System.out.println(searchItem);                }        }}
