solr域配置&solr代码实现搜索

首先在配置文件**solrhome\\collection1\\conf\\schema.xml**文件

<fieldType name="text_ik" class="solr.TextField" >
          <analyzer class="org.wltea.analyzer.lucene.IKAnalyzer"/> 
        </fieldType>
        
        <field name="item_goodsid" type="long" indexed="true" stored="true"/>
        <field name="item_title" type="text_ik" indexed="true" stored="true"/>
        <field name="item_price" type="double" indexed="true" stored="true"/>
        <field name="item_image" type="string" indexed="false" stored="true" />
        <field name="item_category" type="string" indexed="true" stored="true" />
        <field name="item_seller" type="text_ik" indexed="true" stored="true" />
        <field name="item_brand" type="string" indexed="true" stored="true" />
        
        <field name="item_keywords" type="text_ik" indexed="true" stored="false" multiValued="true"/>
        <copyField source="item_title" dest="item_keywords"/>
        <copyField source="item_category" dest="item_keywords"/>
        <copyField source="item_seller" dest="item_keywords"/>
        <copyField source="item_brand" dest="item_keywords"/>
        
        <dynamicField name="item_spec_*" type="string" indexed="true" stored="true" />

在pojo中对应的列上加上**@Filed**注解   liru**@Filed("item\_title") ** 名字要与配置文件中的域的名字相对应

在实现类中的spring配置文件中加入**applicationContext-solr.xml**

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:context="http://www.springframework.org/schema/context"
    	xmlns:solr="http://www.springframework.org/schema/data/solr"
    	xsi:schemaLocation="http://www.springframework.org/schema/data/solr 
      		http://www.springframework.org/schema/data/solr/spring-solr-1.0.xsd
    		http://www.springframework.org/schema/beans 
    		http://www.springframework.org/schema/beans/spring-beans.xsd
    		http://www.springframework.org/schema/context 
    		http://www.springframework.org/schema/context/spring-context.xsd">
    	
    	
    	<solr:solr-server id="solrServer" url="http://127.0.0.1:8080/solr" />
    
       
    	
    	<bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
    		<constructor-arg ref="solrServer" />
    	</bean>
    </beans>

在solr实现方法中实现solr搜索的高亮显示(一般应用于商品搜索的显示)

**ItemSearchServiceImpl.java**

package com.pinyougou.search.service.impl;
    
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.solr.core.SolrTemplate;
    import org.springframework.data.solr.core.query.Criteria;
    import org.springframework.data.solr.core.query.HighlightOptions;
    import org.springframework.data.solr.core.query.HighlightQuery;
    import org.springframework.data.solr.core.query.Query;
    import org.springframework.data.solr.core.query.SimpleHighlightQuery;
    import org.springframework.data.solr.core.query.SimpleQuery;
    import org.springframework.data.solr.core.query.result.HighlightEntry;
    import org.springframework.data.solr.core.query.result.HighlightEntry.Highlight;
    import org.springframework.data.solr.core.query.result.HighlightPage;
    import org.springframework.data.solr.core.query.result.ScoredPage;
    
    import com.alibaba.dubbo.config.annotation.Service;
    import com.pinyougou.pojo.TbItem;
    import com.pinyougou.search.service.ItemSearchService;
    
    //设置一个等待时间  避免相应超时  第一次搜索会比较慢
    @Service(timeout=5000)
    public class ItemSearchServiceImpl implements ItemSearchService {
    
    	@Autowired
    	private SolrTemplate solrTemplate;
    	
    	public Map search(Map searchMap) {
    		Map map  =new HashMap();		
    		HighlightQuery query = new SimpleHighlightQuery();
    		HighlightOptions highlightOptions = new HighlightOptions().addField("item_title");
    		highlightOptions.setSimplePrefix("<em style='color:red'>");
    		highlightOptions.setSimplePostfix("</em>");
    		query.setHighlightOptions(highlightOptions);
    		
    		Criteria criteria = new Criteria("item_keywords").is(searchMap.get("keywords"));
    		query.addCriteria(criteria);
    		
    		HighlightPage<TbItem> page = solrTemplate.queryForHighlightPage(query, TbItem.class);
    		
    		List<HighlightEntry<TbItem>> entryList = page.getHighlighted();
    		for (HighlightEntry<TbItem> entry : entryList) {
    			List<Highlight> highlightList = entry.getHighlights();
    			//获取实体 把highlightList填装进去
    			TbItem item = entry.getEntity();
    			item.setTitle(highlightList.get(0).getSnipplets().get(0));
    		}
    		map.put("rows", page.getContent());
    		return map;
    	}
    
    }

前端使用angular

所以可以在base.controller  中定义一个filter  实现对后端传过来的  高亮显示的html代码的放行

页面上使用**ng-bind-html**方法
