Spring集成Solr搜索引擎

标签：service   org   simple   实现   parse   integer   etl   建立   name   

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
<!--定义solr的server-->
<bean id="solrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
<constructor-arg index="0" value="http://192.168.10.188:8080/solr/core1"/>
<!-- 设置响应解析器 -->
<property name="parser">
<bean class="org.apache.solr.client.solrj.impl.XMLResponseParser"/>
</property>
<!-- 设置重试次数-->
<property name="maxRetries" value="1"/>
<!-- 建立连接的最长时间 -->
<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();

}
