添加商品数据

### Spring容器 ###

由Spring容器，来管理SolrServer  
将SolrServer注入Spring容器

添加配置文件  
applicationContext-solr.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    
        
        <bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
            <constructor-arg name="baseURL" value="http://192.168.25.154:8080/solr/collection1"/>
        </bean>
        
        
    
    </beans>

### ServerImpl ###

业务逻辑

1、查询所有商品数据  
2、创建一个SolrServer对象  
3、为每个商品创建一个SolrInputDocument对象  
4、为文档添加域  
5、向索引库中添加文档  
6、返回TaotaoResult

@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<SearchItem> 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();
        }
    
    }

如果，采用Dubbo分布式服务  
需要发布服务

<dubbo:service interface="com.taotao.search.service.SearchItemService" ref="searchItemServiceImpl" timeout="300000"/>

调用的模块，引用服务

<dubbo:reference interface="com.taotao.search.service.SearchItemService" id="searchItemService" />
