品优购项目记录:day09

今日目标:

(1)完成solr环境安装、中文解析器和业务域的配置

(2)会使用Spring Data Solr完成增删改查操作

(3)完成批量数据导入

(4)完成按关键字搜索功能

(5)完成高亮显示关键字的功能

(6)完成更新索引库的功能

 

 

 

1、Solr环境搭建和配置

准备工作:安装Solr的环境以及solrhome的基础配置

1.1 在solrhome中的collction1下的conf目录中打开 schema.xml 配置业务域

<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" />

1.2 在solrhome中的collction1下的conf目录中打开 schema.xml 配置复制域

<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"/>

 

1.3 在solrhome中的collction1下的conf目录中打开 schema.xml 配置动态域

<dynamicField name="item_spec_*" type="string" indexed="true" stored="true" />

 

 

2、批量导入数据到索引库

说明:批量导入数据到索引库这一操作,一般只执行一次,所以我们不需要将其放入后台系统中,我们单独建立一个模块打成jar包,让用户可以通过命令行执行这一操作即可

准备工作:搭建单独的模块,名称:pinyougou-solr-util

2.1 导入商品数据到索引库

(1)导入依赖

        </dependency>
    </dependencies>

</project>

 

(2)编写配置文件(applicationContext-service.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:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">


	<context:component-scan base-package="com.pinyougou.solrutil"/>
   
</beans>

 

(3)编写SolrUtil类,先进行数据查询测试,然后再使用solr进行正式导入

package com.pinyougou.solrutil;

import com.pinyougou.mapper.TbItemMapper;
import com.pinyougou.pojo.TbItem;
import com.pinyougou.pojo.TbItemExample;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * Solr
 * Author xushuai
 * Description
 */
@Component
public class SolrUtil {

    @Autowired
    private TbItemMapper itemMapper;


    public static void main(String[] args){
        ApplicationContext ac =
                new ClassPathXmlApplicationContext("classpath*:spring/applicationContext*.xml");
        SolrUtil solrUtil = ac.getBean(SolrUtil.class);
        // 执行导入
        solrUtil.importData();
    }

    /**
     * 导入商品数据到索引库
     */
    private void importData() {
        // 构造查询条件
        TbItemExample example = new TbItemExample();
        example.createCriteria().andStatusEqualTo(TbItem.STATUS_NORMAL);
        // 执行查询
        List<TbItem> tbItems = itemMapper.selectByExample(example);

        for (TbItem item : tbItems) {
            System.out.println(item.getTitle());
        }

    }

}

 

(4)输出

 

(5)修改pojo中的实体类TbItem,将对应业务域加到对应的属性上,只注意加了@Field注解的字段

    @Field
    private Long id;

    @Field("item_title")
    private String title;

    private String sellPoint;

    @Field("item_price")
    private BigDecimal price;

    private Integer stockCount;

    private Integer num;

    private String barcode;

    @Field("item_image")
    private String image;

    private Long categoryid;

    private String status;

    private Date createTime;

    private Date updateTime;

    private String itemSn;

    private BigDecimal costPirce;

    private BigDecimal marketPrice;

    private String isDefault;

    @Field("item_goodsId")
    private Long goodsId;

    private String sellerId;

    private String cartThumbnail;

    @Field("item_category")
    private String category;

    @Field("item_brand")
    private String brand;

    private String spec;

    @Field("item_seller")
    private String seller;

注意:使用Field注解之前,需要在pojo的pom.xml中引入solr的依赖

 

 

(6)配置 Solr 配置文件(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://127.0.0.1:8080/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>

 

(7)修改SolrUtil,注入SolrTemplate,然后修改importData方法,实现数据导入Solr索引库

 

(8)查看索引库

 

2.2 导入规格数据到索引库

(1)修改pojo工程中的item实体,新增一个属性用于保存动态域信息,使用 @Dynamic表示为动态域

    @Dynamic
    @Field("item_spec_*")
    private Map<String, String> specMap;

注意:必须加入泛型限定<String, String>,否则保存时,会报错,他在将数据替换到通配符上会出错

 

(2)修改SolrUtil中的importData方法,使用spec转换为Map集合,保存到索引库

 

 

 

 

3、搜索服务工程搭建

3.1 搭建工程

导入相关依赖,编写相关配置文件,参考content-interface和content-service,只需要注意导入solr的配合文件即可

3.2 服务层接口

(search-interface),新建ItemSearchService,并添加搜索方法

package com.pinyougou.search.service;

import java.util.Map;

/**
 * 搜索服务层接口
 * Author xushuai
 * Description
 */
public interface ItemSearchService {

    /**
     * 搜索
     *
     * @param searchMap 搜索条件
     * @return java.util.Map
     */
    Map search(Map searchMap);

}

3.3 服务层实现(search-service)

新建ItemSearchServiceImpl,实现ItemSearchService

package com.pinyougou.search.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.pinyougou.pojo.TbItem;
import com.pinyougou.search.service.ItemSearchService;
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.Query;
import org.springframework.data.solr.core.query.SimpleQuery;
import org.springframework.data.solr.core.query.result.ScoredPage;

import java.util.HashMap;
import java.util.Map;

/**
 * 搜索服务实现
 * Author xushuai
 * Description
 */
@Service
public class ItemSearchServiceImpl implements ItemSearchService {

    @Autowired
    private SolrTemplate solrTemplate;

    @Override
    public Map search(Map searchMap) {
        // 构造查询条件
        Query query = new SimpleQuery("*:*");
        Criteria criteria = new Criteria("item_keywords");
        criteria.is(searchMap.get("keywords"));
        query.addCriteria(criteria);

        // 执行查询
        ScoredPage<TbItem> pageInfo = solrTemplate.queryForPage(query, TbItem.class);

        // 返回结果
        Map resultMap = new HashMap();
        resultMap.put("rows", pageInfo.getContent());

        return resultMap;
    }
}

 

 

4、搜索控制层服务

4.1 搭建控制层工程

名称为:pinyougou-search-web,引入相关依赖和相关配置文件,还需要导入相关静态资源

4.2 在search-web中,新建ItemSearchController

package com.pinyougou.search.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.pinyougou.search.service.ItemSearchService;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

/**
 * 搜索控制层
 * Author xushuai
 * Description
 */
@RestController
@RequestMapping("/itemsearch")
public class ItemSearchController {

    @Reference
    private ItemSearchService itemSearchService;

    @RequestMapping("/search")
    public Map search(@RequestBody Map searchMap) {
       return itemSearchService.search(searchMap);
    }
}

 

4.3 编写searchService.js和searchController.js

(1)searchService.js

app.service('searchService',function ($http) {
    
    // 搜索
    this.search = function (searchMap) {
        return $http.post("itemsearch/search.do", searchMap);
    }
    
});

(2)searchController.js

app.controller('searchController',function ($scope,searchService) {
   
    $scope.search = function () {
        searchService.search($scope.searchMap).success(
            function (rtn) {
                $scope.resultMap = rtn;
            }
        );
    }
});

 

4.4 在页面中引入相关js和基本的angular js指令

 

4.5 给所有框和搜索按钮绑定变量和单击事件

 

4.6 循环遍历查询结果,展示搜索结果

 

4.7 效果
