SPRINGMVC整合SOLR

1. <dependency>
2.  
   <groupId>org.apache.solr</groupId>
3.  
   <artifactId>solr-solrj</artifactId>
4.  
   <version>7.0.1</version>
5.  
   </dependency>

2、配置一个spring-solr.xml

1.  
   <?xml version="1.0" encoding="UTF-8"?>
2.  
   <beans xmlns="http://www.springframework.org/schema/beans"
3.  
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:http="http://www.springframework.org/schema/c"
4.  
   xsi:schemaLocation="http://www.springframework.org/schema/beans
5.  
   http://www.springframework.org/schema/beans/spring-beans.xsd">
6.  
    
7.  
   <bean id="httpSolrClient"
8.  
   class="org.apache.solr.client.solrj.impl.HttpSolrClient">
9.  
   <constructor-arg index="0" value="http://192.168.52.13:8983/solr/comInfo_core"/>
10.  
    <!-- 建立连接的最长时间 -->
11.  
    <!--<property name="connectionTimeout"
12.  
    value="${solr.connectionTimeout}"/>-->
13.  
    <property name="connectionTimeout" value="3000"/>
14.  
    </bean>
15.  
     
16.  
    </beans>

3、在这里我是将solr交给spring管理的，只写了service层跟serviceImpl

1.  
   @Service
2.  
   public class SolrImpl implements IsolrService {
3.  
   @Autowired
4.  
   HttpSolrClient client;
5.  
   @Override
6.  
   public List<CommodityInfoDto> solr(String text) throws IOException, SolrServerException {
7.  
    
8.  
   SolrQuery query=new SolrQuery();
9.  
    
10.  
    String queryText="infoName:"+text+"* or infoArtist:"+text+" or infoAddress:"+text+"*";
11.  
    query.set("q",queryText);
12.  
    //1、过滤器
13.  
    //query.set("fq","infoPrice:[1 TO 1000]");
14.  
    //2、排序
15.  
    //query.set("sort","infoPrice desc","id asc");
16.  
    //3、设置查询到的文档返回的域对象
17.  
    query.set("fi","id,infoName,infoArtist,infoAddress");
18.  
     
19.  
    //4、设置默认查询的域
20.  
    query.set("df","infoName","infoArtist","infoAddress");
21.  
     
22.  
    //5.分页
23.  
    query.set("start",0);
24.  
    query.set("rows",10);
25.  
     
26.  
    //6、高亮
27.  
    //设置高亮域(设置的域必须在查询条件中存在)
28.  
    query.addHighlightField("infoName");
29.  
    query.addHighlightField("infoArtist");
30.  
    query.addHighlightField("infoAddress");
31.  
    //前缀
32.  
    query.setHighlightSimplePre("<em style='color:red'>");//这里的话，如果用thymeleaf模板，css样式生效需要加th:utext...
33.  
    //后缀
34.  
    query.setHighlightSimplePost("</em>");
35.  
     
36.  
    QueryResponse response = client.query(query);
37.  
    //普通查询
38.  
    SolrDocumentList results = response.getResults();
39.  
    List<CommodityInfoDto> comList=new ArrayList<CommodityInfoDto>();
40.  
    //高亮查询
41.  
    NamedList<SimpleOrderedMap> namedList= (NamedList<SimpleOrderedMap>) response.getResponse().get("highlighting");
42.  
    //k是id,内部的map的key是域名,其value是高亮的值集合
43.  
    /*Map<String, Map<String, List<String>>> highlighting = response.getHighlighting();*/
44.  
    System.out.println("匹配的结果总数是-------"+results.getNumFound());
45.  
    for(SolrDocument document:results){
46.  
    CommodityInfoDto comInfo=new CommodityInfoDto();
47.  
    Integer id=Integer.parseInt((String)document.get("id"));
48.  
    comInfo.setInfoId(id);;
49.  
    comInfo.setInfoName((String)document.get("infoName"));
50.  
    comInfo.setInfoImg((String)document.get("infoImg"));
51.  
    comInfo.setInfoArtist((String)document.get("infoArtist"));
52.  
    comInfo.setInfoTime((String)document.get("infoTime"));
53.  
    comInfo.setInfoAddress((String)document.get("infoAddress"));
54.  
    comInfo.setInfoPrice((String)document.get("infoPrice"));
55.  
    comInfo.setInfoTicket((String)document.get("infoTicket"));
56.  
    for(int i=0;i<namedList.size();i++){
57.  
    String nameId = namedList.getName(i);
58.  
    if(id.toString().equals(nameId)){
59.  
    SimpleOrderedMap map=namedList.getVal(i);//获取某个商品的高亮
60.  
    //这里是需要加判断的，不然会有空值加进去
61.  
    ArrayList infoName = (ArrayList) map.get("infoName");
62.  
    if(infoName!=null&& infoName.size()>0){
63.  
    String highInfoName=(String)infoName.get(0);
64.  
    comInfo.setInfoName(highInfoName);
65.  
    }
66.  
     
67.  
     
68.  
    ArrayList infoArtist = (ArrayList) map.get("infoArtist");
69.  
    if(infoArtist!=null&& infoArtist.size()>0){
70.  
    String highinfoArtist=(String)infoArtist.get(0);
71.  
    comInfo.setInfoArtist(highinfoArtist);
72.  
    }
73.  
     
74.  
     
75.  
    ArrayList infoAddress = (ArrayList) map.get("infoAddress");
76.  
    if(infoAddress!=null&& infoAddress.size()>0){
77.  
    String highinfoAddress=(String)infoAddress.get(0);
78.  
    comInfo.setInfoArtist(highinfoAddress);
79.  
    }
80.  
    }
81.  
    }
82.  
    comList.add(comInfo);
83.  
    }
84.  
    return comList;
85.  
    }
86.  
    }

4、我这里是通过用户输入一个字符，里面内容包括商品名字+商品艺人姓名+商品地址，联合查询，查询出来的对象也不会是重复的数据

1.  
   //查询商品
2.  
   @Test
3.  
   public void test11(){
4.  
   try {
5.  
   List<CommodityInfoDto> list = solr.solr("演唱");
6.  
   for(CommodityInfoDto com:list){
7.  
   System.out.println("-------------->"+com);
8.  
   }
9.  
   } catch (IOException e) {
10.  
    e.printStackTrace();
11.  
    } catch (SolrServerException e) {
12.  
    e.printStackTrace();
13.  
    }
14.  
    }
15.  
    }
