2.分析需要匯入索引庫的資料資訊，將這些屬性重新封裝成一個POJO類
同時別忘了依賴SOLR架包

3.編寫Mapper.java和Mapper.xml
由於是多表查詢，原來逆向工程的Mapper無法使用，所以需要自己寫
Mapper.java中寫介面，
Mapper.xml中實現如下

<mapper namespace="com.taotao.search.mapper.SearchItemMapper" >

    <select id="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
    </select>

</mapper>

4.在schea.xml配置檔案中配置IK分詞方法在第一步中其實已經做了

 <!-- IKAnalyzer-->
<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.編寫單機版solr的配置檔案

<!-- 單機版solr的連線 -->
    <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.實現

《1》編寫介面
TaotaoResult importItemsToIndex();
《2》實現介面

/**
 * 商品資料匯入索引庫
 * <p>Title: SearchItemServiceImpl</p>
 * <p>Description: </p>
 * <p>Company: www.itcast.cn</p> 
 * @version 1.0
 */
@Service
public class SearchItemServiceImpl implements SearchItemService {

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

    @Override
    public TaotaoResult importItemsToIndex() {
        try {
            //1、先查詢所有商品資料
            List<SearchItem> itemList = searchItemMapper.getItemList();
            //2、遍歷商品資料新增到索引庫
            for (SearchItem searchItem : itemList) {
                //建立文件物件
                SolrInputDocument document = new SolrInputDocument();
                //向文件中新增域
                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());
                //把文件寫入索引庫
                solrServer.add(document);
            }
            //3、提交
            solrServer.commit();
        } catch (Exception e) {
            e.printStackTrace();
            return TaotaoResult.build(500, "資料匯入失敗");
        }
        //4、返回新增成功
        return TaotaoResult.ok();
    }

}

《3》控制層

@Controller
public class IndexManagerController {

    @Autowired
    private SearchItemService searchItemService;

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