Spring整合solr实现文章的添加与搜索

maven里添加依赖

   
        org.apache.solr
        solr-solrj
        4.10.2
    
    
        commons-logging
        commons-logging
        1.2
    

spring配置文件里添加

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;
    }
}

可能的问题

如果想向solr添加带html标签的文本，可以使用jsoup选中元素，调用text()方法脱去全部的html标签，再保存到索引中。
