solr索引库添加

1.solr的安装与配置

2.分析需要导入索引库的数据信息，将这些属性重新封装成一个POJO类
同时别忘了依赖SOLR架包

3.编写Mapper.java和Mapper.xml
由于是多表查询，原来逆向工程的Mapper无法使用，所以需要自己写
Mapper.java中写接口，
Mapper.xml中实现如下

"com.taotao.search.mapper.SearchItemMapper" >

    "getItemList" resultType="com.taotao.common.pojo.SearchItem">
        SELECT
            a.id,
            a.title,
            a.sell_point,
            a.price,
            a.image,
            b. NAME category_name,
            c.item_desc
        FROM
            tb_item a
        LEFT JOIN tb_item_cat b ON a.cid = b.id
        LEFT JOIN tb_item_desc c ON a.id = c.item_id
        WHERE
            a.`status` = 1
    

4.在schea.xml配置文件中配置IK分词方法在第一步中其实已经做了

 
<fieldType name="text_ik" class="solr.TextField">
  <analyzer class="org.wltea.analyzer.lucene.IKAnalyzer"/>
fieldType>

<field name="item_title" type="text_ik" indexed="true" stored="true"/>
<field name="item_sell_point" type="text_ik" indexed="true" stored="true"/>
<field name="item_price"  type="long" indexed="true" stored="true"/>
<field name="item_image" type="string" indexed="false" stored="true" />
<field name="item_category_name" type="string" indexed="true" stored="true" />
<field name="item_desc" type="text_ik" indexed="true" stored="false" />

<field name="item_keywords" type="text_ik" indexed="true" stored="false" multiValued="true"/>
<copyField source="item_title" dest="item_keywords"/>
<copyField source="item_sell_point" dest="item_keywords"/>
<copyField source="item_category_name" dest="item_keywords"/>
<copyField source="item_desc" dest="item_keywords"/>

5.编写单机版solr的配置文件

    <bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
        <constructor-arg name="baseURL" value="http://127.0.0.1:8090/solr/collection1"/>
    bean>

6.实现

《1》编写接口
TaotaoResult importItemsToIndex();
《2》实现接口

/**
 * 商品数据导入索引库
 * 
Title: SearchItemServiceImpl
 * 
Description: 
 * 
Company: www.itcast.cn
 
 * @version 1.0
 */
@Service
public class SearchItemServiceImpl implements SearchItemService {

    @Autowired
    private SearchItemMapper searchItemMapper;
    @Autowired
    private SolrServer solrServer;

    @Override
    public TaotaoResult importItemsToIndex() {
        try {
            //1、先查询所有商品数据
            List itemList = searchItemMapper.getItemList();
            //2、遍历商品数据添加到索引库
            for (SearchItem searchItem : itemList) {
                //创建文档对象
                SolrInputDocument document = new SolrInputDocument();
                //向文档中添加域
                document.addField("id", searchItem.getId());
                document.addField("item_title", searchItem.getTitle());
                document.addField("item_sell_point", searchItem.getSell_point());
                document.addField("item_price", searchItem.getPrice());
                document.addField("item_image", searchItem.getImage());
                document.addField("item_category_name", searchItem.getCategory_name());
                document.addField("item_desc", searchItem.getItem_desc());
                //把文档写入索引库
                solrServer.add(document);
            }
            //3、提交
            solrServer.commit();
        } catch (Exception e) {
            e.printStackTrace();
            return TaotaoResult.build(500, "数据导入失败");
        }
        //4、返回添加成功
        return TaotaoResult.ok();
    }

}

《3》控制层

@Controller
public class IndexManagerController {

    @Autowired
    private SearchItemService searchItemService;

    @RequestMapping("/index/import")
    @ResponseBody
    public TaotaoResult importIndex() {
        TaotaoResult taotaoResult = searchItemService.importItemsToIndex();
        return taotaoResult;
    }
}
