solr-搜索解决方案

目标1：完成solr环境安装、中文分析器和业务域的配置

目标2：会使用Spring Data Solr完成增删改查操作

目标3：完成批量数据导入功能

目标4：完成按关键字搜索功能

1.业务接口层

public interface ItemSearchService {
    /**
     * 搜索
     * @param 
     * @return
     */
    public Map<String,Object> search(Map searchMap);
}

2.服务实现层

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服务器地址 -->
    <solr:solr-server id="solrServer" url="http://192.168.188.128:8080/solr" />
    <!-- solr模板，使用solr模板可对索引库进行CRUD的操作 -->
    <bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
        <constructor-arg ref="solrServer" />
    </bean>
</beans>

 

在src/main/resources/spring 下applicationContext-service.xml   ： dubbo端口20884

@Service(timeout = 3000)
public class ItemSearchServiceImpl2 implements ItemSearchService {

    @Autowired
    private SolrTemplate solrTemplate;

    @Override
    public Map<String, Object> search(Map searchMap) {

        //获取查询条件
        String keywords = String.valueOf(searchMap.get("keywords"));
        Integer pageNo = Integer.parseInt(String.valueOf(searchMap.get("pageNo")));
        //获取每页查询条数
        Integer pageSize = Integer.parseInt(String.valueOf(searchMap.get("pageSize")));


        Map<String,Object> resultMap=new HashMap<>();
        //封装查询对象
        Query query=new SimpleQuery();
        //添加查询条件
        Criteria criteria=new Criteria("item_keywords").is(searchMap.get("keywords"));
        //将查询的条件放入查询的对象
        query.addCriteria(criteria);
        if (pageNo == null || pageNo <= 0){
            pageNo=1;
        }
        //当前页开始是第几条
        Integer start = (pageNo-1)*pageSize;
        //设置第几条开始
        query.setOffset(start);
        //每页查询多少条数据
        query.setRows(pageSize);
        //去solr查询并返回结果
        ScoredPage<Item> page = solrTemplate.queryForPage(query, Item.class);
        resultMap.put("rows",page.getContent());
        return resultMap;
    }
}

3.控制层

@RestController
@RequestMapping("/itemsearch")
public class ItemSearchController {
    @Reference
    private ItemSearchService itemSearchService;
    
    @RequestMapping("/search")
    public Map<String, Object> search(@RequestBody Map searchMap ){
        return  itemSearchService.search(searchMap);
    }    
}
