很多人表示不知道spring整合solr应该怎样去实现，那么假如你对这个方面也有疑惑的话，就请一起来通过下面的文章来了解一下吧。
maven里添加依赖
<dependency> <groupId>org.apache.solr</groupId> <artifactId>solr-solrj</artifactId> <version>4.10.2</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency>
spring配置文件里添加
<bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer"> <constructor-arg index="0" value="http://192.168.25.128:8080/solr/collection1" /> </bean>
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
ublic List < Article > queryArticles(String keyword, SolrQueryPageInfo solrQueryPageInfo)
{
List < Article > 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("<em>");
solrQuery.setHighlightSimplePost("</em>");
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 < String, Map < String, List < String >>> 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 < String, List < String >> map = mapMapHighlighting.get(id); //一个商品，一个json对象
for (Map.Entry < String, List < String >> 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 < Article > 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 < Article > articles;
public int getTotal()
{
return total;
}
public void setTotal(int total)
{
this.total = total;
}
public List < Article > getArticles()
{
return articles;
}
public void setArticles(List < Article > 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;
}
}index_query.jsp
