JAVA工程对Solr进行增删改以及封装一个Query对象

来源：互联网发布：刺客信条战斗力知乎编辑：程序博客网时间：2024/06/15 02:32

今天写了个JAVA工程来对以及部署在tomcat上的Solr项目进行增删改查操作。

首先先获取到HttpSolrServer。

HttpSolrServer httpSolrServer = new HttpSolrServer("http://localhost:8080/solr/collection1");

传进去的参数就是Solr的访问地址。
向solr服务器添加一个文档

public void addSolrIndex() throws Exception, IOException {// solr web serverSolrInputDocument document = new SolrInputDocument();document.addField("id", "0001");document.addField("content", "哈哈18岁");httpSolrServer.add(document);httpSolrServer.commit();}

删除solr服务器中的索引

public void deleteSolrIndex() throws Exception {// httpSolrServer.deleteByQuery("*:*");httpSolrServer.deleteById("test0001");httpSolrServer.commit();}

更新solr服务器中的索引

public void updateSolrIndex() throws Exception {SolrInputDocument document = new SolrInputDocument();document.addField("id", "test0001");document.addField("content", "赵老师30岁");httpSolrServer.add(document);httpSolrServer.commit();}

查询操作

public void searchSolrIndex() {try {// 封装查询条件SolrQuery query = new SolrQuery();query.set("q", "花儿朵朵");// 添加过滤条件// query.setFilterQueries("product_name:花儿朵朵",// "product_catalog_name:辣条");String  s = "10-20";String[] split = s.split("-");query.setFilterQueries("product_price:["+split[0]+" TO "+split[1]+"]");// 排序query.addSort("product_price", ORDER.desc);query.setStart(0);query.setRows(10);// 查询返回的域// query.setFields("", "");// 设置默认查询域query.set("df", "product_keywords");// 设置高亮query.setHighlight(true);query.addHighlightField("product_name");query.setHighlightSimplePre("<em color=\"red\">");query.setHighlightSimplePost("</em>");// 执行查询并返回一个QueryResponse对象QueryResponse response = httpSolrServer.query(query);SolrDocumentList results = response.getResults();// 本次查询命中的文档数量long numFound = results.getNumFound();System.out.println("numFound = " + numFound);// 获取高亮显示的内容Map<String, Map<String, List<String>>> highlighting = response.getHighlighting();for (SolrDocument solrDocument : results) {String id = (String) solrDocument.get("id");String product_name = "";List<String> list = highlighting.get(id).get("product_name");if (null != list && list.size() > 0) {product_name = list.get(0);} else {product_name = (String) solrDocument.get("product_name");}String product_catalog_name = (String) solrDocument.get("product_catalog_name");float product_price = (float) solrDocument.get("product_price");String product_picture = (String) solrDocument.get("product_picture");System.out.println("id = " + id + " \t product_name=" + product_name + " \t product_catalog_name="+ product_catalog_name + " \t product_price=" + product_price + " \t product_picture="+ product_picture);}} catch (SolrServerException e) {// TODO Auto-generated catch blocke.printStackTrace();}}
