   public class SolrTest {    @After    public void tearDown() throws Exception {    }    //添加索引    @Test    public void testAdd() throws SolrServerException, IOException {        //创建和solr服务器的连接        String url="http://localhost:8080/solr";        SolrServer solrServer=new HttpSolrServer(url);        //创建一个文档对象        SolrInputDocument document = new SolrInputDocument();        document.addField("id","solr001");        document.addField("product_name", "魅族手机");        document.addField("product_price", 3000);        solrServer.add(document);        solrServer.commit();    }    //根据id删除    @Test    public void deleteDocumentById() throws Exception{        //创建和solr服务器的连接        String url="http://localhost:8080/solr";        SolrServer solrServer=new HttpSolrServer(url);        solrServer.deleteById("solr001");        solrServer.commit();    }    //删除全部    @Test    public void deleteAll()throws Exception{        //创建和solr服务器的连接        String url="http://localhost:8080/solr";        SolrServer solrServer=new HttpSolrServer(url);        solrServer.deleteByQuery("*:*");        solrServer.commit();    }    //更新和添加一样 略    @Test    public void testSearch() throws Exception{        //创建和solr服务器的连接        String url="http://localhost:8080/solr";        SolrServer solrServer=new HttpSolrServer(url);        //创建查询对象 SolrQuery是SolrParams 的子类        SolrQuery solrQuery = new SolrQuery();        //solrQuery.set("q", "*:*");        //solrQuery.setQuery("*:*");        //设置默认搜索域        solrQuery.set("df", "product_name");        //设置查询条件        solrQuery.setQuery("手机");        //设置过滤条件        solrQuery.addFilterQuery("product_price:[100 TO 6600]");        //设置排序条件        solrQuery.setSort("product_price", ORDER.asc);        //设置分页条件        solrQuery.setStart(0);        solrQuery.setRows(10);        //设置显示的域        solrQuery.setFields("id","product_name","product_price");        solrQuery.setHighlight(true);        solrQuery.addHighlightField("product_name");        solrQuery.setHighlightSimplePre("<span style='color:red'>");        solrQuery.setHighlightSimplePost("</span>");        //执行查询        QueryResponse queryResponse = solrServer.query(solrQuery);        //取文档列表        SolrDocumentList results = queryResponse.getResults();        System.out.println("查询结果总量:"+results.getNumFound());        //遍历查询结果        for (SolrDocument solrDocument : results) {            System.out.println(solrDocument.get("id"));            System.out.println(solrDocument.get("product_name"));            System.out.println(solrDocument.get("product_price"));            System.out.println(solrDocument.get("product_catalog_name"));            System.out.println(solrDocument.get("product_picture"));            Map<String, Map<String, List<String>>> highlighting = queryResponse.getHighlighting();            //key 域名            Map<String, List<String>> map = highlighting.get(solrDocument.get("id"));            List<String> list = map.get("product_name");            System.out.println(list.get(0));            System.out.println("--------------");        }    }}
