添加文章
Contoller或service里添加

    @Autowired
    private SolrServer solrServer;

 public int addArticle(Article article) {
        int result = articleMapper.addArticle(article);

        SolrInputDocument inputDocument = new SolrInputDocument();
        //向文档中添加域以及对应的值,注意:所有的域必须在schema.xml中定义过,前面已经给出过我定义的域。
        UUID uuid = UUID.randomUUID();
        inputDocument.addField("id", uuid);
        inputDocument.addField("article_title", article.getTitle());
        inputDocument.addField("article_content", article.getContent());
        inputDocument.addField("article_id", article.getAid());
        try {
            solrServer.add(inputDocument);
            solrServer.commit();
        } catch (SolrServerException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }

检索文章

 public List
queryArticles(String keyword,SolrQueryPageInfo solrQueryPageInfo) { List
articleList = new ArrayList<>(); SolrQuery solrQuery = new SolrQuery(); solrQuery.set("q",keyword); solrQuery.set("df","article_keywords");//df=>default field solrQuery.setSort("id", SolrQuery.ORDER.asc); solrQuery.setStart(solrQueryPageInfo.getPageIndex()*solrQueryPageInfo.getPageSize()); solrQuery.setRows(solrQueryPageInfo.getPageSize()); //开启高亮显示 solrQuery.setHighlight(true); solrQuery.addHighlightField("article_title"); solrQuery.addHighlightField("article_content"); solrQuery.setHighlightSimplePre(""); solrQuery.setHighlightSimplePost(""); QueryResponse queryResponse = null; try { queryResponse = solrServer.query(solrQuery); } catch (SolrServerException e) { e.printStackTrace(); } SolrDocumentList solrDocumentList = queryResponse.getResults(); int total = (int) solrDocumentList.getNumFound(); solrQueryPageInfo.setTotal(total); Map>> mapMapHighlighting = queryResponse.getHighlighting(); for(SolrDocument solrDocument : solrDocumentList) { Article article = new Article(); String id = (String)solrDocument.get("id"); String article_title = (String)solrDocument.get("article_title"); String article_content = (String)solrDocument.get("article_content"); Long article_id = (Long)solrDocument.get("article_id"); article.setTitle(article_title); article.setContent(article_content); article.setAid(article_id.intValue()); Map> map = mapMapHighlighting.get(id);//一个商品,一个json对象 for(Map.Entry> entry : map.entrySet()) { if(entry.getKey().equals("article_title")) { article.setTitle(entry.getValue().get(0)); } if(entry.getKey().equals("article_content")) { article.setContent(entry.getValue().get(0)); } } articleList.add(article); } return articleList; }

Controller里调用

 @RequestMapping("query")
    public void queryArticles(String keyword, Model model, SolrQueryPageInfo solrQueryPageInfo, HttpServletResponse response) throws IOException {
        response.setContentType("text/html;charset=utf-8");

        ArticlePageInfo articlePageInfo = new ArticlePageInfo();
        List
articleList = articleService.queryArticles(keyword,solrQueryPageInfo); articlePageInfo.setTotal(solrQueryPageInfo.getTotal()); articlePageInfo.setArticles(articleList); String jsonString = JSON.toJSONString(articlePageInfo); response.getWriter().println(jsonString); } ArticlePageInfo public class ArticlePageInfo { int total; List
articles; public int getTotal() { return total; } public void setTotal(int total) { this.total = total; } public List
getArticles() { return articles; } public void setArticles(List
articles) { this.articles = articles; } } SolrQueryPageInfo public class SolrQueryPageInfo { int pageIndex; int pageSize; int total; public int getPageIndex() { return pageIndex; } public void setPageIndex(int pageIndex) { this.pageIndex = pageIndex; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getTotal() { return total; } public void setTotal(int total) { this.total = total; } }
