1、导入jar包  
<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>1.1</version>  
</dependency>  
2、Spring配置文件中定义solr的bean  
  
<bean id="solrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">  
<constructor-arg index="0" value="http://192.168.10.188:8080/solr/core1"/>  
  
<property name="parser">  
<bean class="org.apache.solr.client.solrj.impl.XMLResponseParser"/>  
</property>  
  
<property name="maxRetries" value="1"/>  
  
<property name="connectionTimeout" value="500"/>  
</bean>  
3、Service中注入solr的bean  
@Service  
@Qualifier("goodsService")  
public class GoodsServiceImpl implements GoodsService \{  
private Logger log = Logger.getLogger(GoodsServiceImpl.class);  
@Resource  
@Qualifier("solrServer")  
private SolrServer solrServer;  
4、实现solr查询  
public List<TGoods> queryGoodsList(GoodsQuery goodsQuery) throws SolrServerException \{  
SolrQuery solrQuery = new SolrQuery();  
//设置关键字  
solrQuery.setQuery(goodsQuery.getName());  
//设置默认检索域  
solrQuery.set("df", "name");  
// 分页  
// solrQuery.setStart(0);  
// solrQuery.setRows(5);  
// 只查询指定域  
solrQuery.set("fl", "id,name,goods\_price,goods\_status,goods\_type,goods\_img,goods\_describle");  
// 设置高亮  
solrQuery.setHighlight(true);  
// 指定高亮域  
solrQuery.addHighlightField("name");  
// 前缀  
solrQuery.setHighlightSimplePre("<span style='color:red'>");  
solrQuery.setHighlightSimplePost("</span>");  
// 执行查询  
QueryResponse response = solrServer.query(solrQuery);  
// 文档结果集  
SolrDocumentList docs = response.getResults();  
Map<String, Map<String, List<String>>> highlighting = response.getHighlighting();  
List<TGoods> goodsList = new ArrayList<TGoods>();  
for (SolrDocument doc : docs) \{  
TGoods goods = new TGoods();  
goods.setId(Integer.parseInt(doc.get("id").toString()));  
goods.setPrice(Double.parseDouble(doc.get("goods\_price").toString()));  
goods.setStatus(Integer.parseInt(doc.get("goods\_status").toString()));  
goods.setType(Integer.parseInt(doc.get("goods\_type").toString()));  
goods.setImg((String)doc.get("goods\_img"));  
goods.setDescrible((String)doc.get("goods\_describle"));  
Map<String, List<String>> map = highlighting.get((String) doc.get("id"));  
List<String> list = map.get("name");  
goods.setName(list.get(0));  
goodsList.add(goods);  
\}  
return goodsList;  
\}  
4、solr实现添加  
public void saveGoods(TGoods goods) throws SolrServerException, IOException \{  
//创建新的文档对象  
SolrInputDocument solrInputDocument = new SolrInputDocument();  
//设置文档的域  
solrInputDocument.setField("id", goods.getId());  
solrInputDocument.setField("name", goods.getName());  
solrInputDocument.setField("goods\_price", goods.getPrice());  
solrInputDocument.setField("goods\_status", goods.getStatus());  
solrInputDocument.setField("goods\_type", goods.getType());  
solrInputDocument.setField("goods\_img", goods.getImg());  
solrInputDocument.setField("goods\_describle", goods.getDescrible());  
//进行添加  
solrServer.add(solrInputDocument);  
//进行手动提交，否则无法进行添加  
solrServer.commit();  
\}  
5、solr实现删除  
public void deleteGoodsById(Integer id) throws SolrServerException, IOException \{  
log.debug("\*\*\*\*\*\*\*\*\*deleteGoodsById\*\*\*\*\*\*\*\*\*\*\*\*" + id);  
solrServer.deleteById(String.valueOf(id));  
solrServer.commit();
