SolrJ

(1) 引入相关依赖

             
                 
      
       org.apache.solr
                  
      
       solr-solrj
              
     

(2) 编写配置文件:applicationContext-solr.xml

(3) 导入数据到solr索引库

@Servicepublic class SearchItemServiceImpl implements SearchItemService {    @Autowired    private SearchItemMapper searchItemMapper;        @Autowired    private SolrServer solrServer;        public Result importItemsToIndex() {        try {            List
     
       itemList = searchItemMapper.getItemList();            for (SearchPojo searchPojo : itemList) {                SolrInputDocument document = new SolrInputDocument();                document.addField("id", searchPojo.getId());                document.addField("item_title", searchPojo.getTitle());                document.addField("item_sell_point", searchPojo.getSell_point());                document.addField("item_price", searchPojo.getPrice());                document.addField("item_image", searchPojo.getImage());                document.addField("item_desc", searchPojo.getItem_desc());                document.addField("item_category_name", searchPojo.getCategory_name());                solrServer.add(document);                            }            solrServer.commit();        } catch (Exception e) {            e.printStackTrace();            return Result.build(500, "索引库导入失败!");        }        return Result.ok();    }}
     

(4) 搜索solr索引库

@Servicepublic class SearchServiceImpl implements SearchService {    @Autowired    private SearchDao searchDao;        public SearchResult search(String queryString, int page, int rows) throws Exception {        SolrQuery query = new SolrQuery(queryString);        if (page < 1) {            page = 1;        }        if (rows < 1) {            rows = 10;        }        query.setStart((page - 1) * rows);        query.setRows(rows);        // 设置默认搜索域        query.set("df", "item_title");        // 设置高亮        query.setHighlight(true);    // 开启高亮        query.addHighlightField("item_title");    // 显示高亮的域        query.setHighlightSimplePre("");    //设置高亮颜色        query.setHighlightSimplePost("");                SearchResult result = searchDao.search(query);        // 计算总页数        long recordCount = result.getRecordCount();        long pages = recordCount / rows;        if (recordCount % rows > 0) {            pages++;        }        result.setTotalPages(pages);                return result;    }}
