1.1 搭建页面环境
1. 引入依赖
2. 将页面复制到gulimall-search的src/main/resources/templates/目录下
3. 调整搜索页面1）引入thymeleafxmlns:th="http://www.thymeleaf.org"2）修改页面静态资源的引入，加上/static/searcheg: 由<link rel="stylesheet" href="./css/index.css">改为：<link rel="stylesheet" href="/static/search/css/index.css">
4. 将静态资源放到linux的nginx相关映射目录下/root/docker/nginx/html/static/search/
5. SwitchHosts配置域名转发1）以管理员身份运行SwitchHosts；2）让所有的search.gulimall.com可以定位到linux的nginx服务
6. 测试1）浏览器访问http://localhost:120002）浏览器访问http://search.gulimall.com/
7. nginx配置
8. 网关配置
9. 测试 http://search.gulimall.com/
1.1.1 引入依赖
<!-- 模板引擎 ：thymeleaf -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional>
</dependency>1.1.2 将检索页面放到gulimall-search的src/main/resources/templates/目录下
1.1.3 调整搜索页面
引入thymeleaf，修改引入静态资源的路径以/static/search开始。以下为了举例，list.html完整代码见 1.9.1 检索页面完整代码
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head><meta charset="UTF-8"><meta name="viewport"content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"><meta http-equiv="X-UA-Compatible" content="ie=edge"><link rel="stylesheet" href="/static/search/css/index.css"><link rel="stylesheet" type="text/css" href="/static/search/font/iconfont.css"><!--<script src="/static/search/js/jquery-3.2.1.min.js"></script>--><script src="/static/search/js/jquery-1.12.4.js"></script><title>Document</title>
</head>
...1.1.4 将静态资源放到linux的nginx相关映射目录下/root/docker/nginx/html/static/ search/
1.1.5 SwitchHosts配置域名转发
(1）以管理员身份运行SwitchHosts；
(2）让所有的search.gulimall.com可以定位到linux的nginx服务
1.1.6 测试
(1）浏览器访问http://localhost:12000
(2）浏览器访问http://search.gulimall.com/
1.1.7 nginx配置
（1）修改gulimall.conf，将 server_name 由 gulimall.com 改为 *.gulimall.com
（2）保存gulimall.conf并重启nginx。# 进入/root/docker/nginx/conf/conf.d/
cd /root/docker/nginx/conf/conf.d/# 进入gulimall.conf，修改server_name
vi gulimall.conf# 重启nginx
docker restart nginx# 查看nginx是否启动成功
docker ps -a
1.1.8 网关配置
- id: gulimall_host_routeuri: lb://gulimall-productpredicates:# 由以下的主机域名访问转发到商品服务- Host=gulimall.com- id: gulimall_search_routeuri: lb://gulimall-searchpredicates:# 由以下的主机域名访问转发到搜索服务- Host=search.gulimall.com1.1.9 重启测试
http://search.gulimall.com/
注意静态资源的路径是否正确；有些图片可能缺失，影响不大。
1.2 调整页面跳转
1.2.1 引入spring-boot-devtools依赖
前面已经引入。
1.2.2 关闭thymeleaf缓存
页面修改后同过Ctrl+Shift+F9对html页面进行重新构建，无需重启项目
spring:thymeleaf:cache: false1.2.3 修改页面能够跳转到商城首页
效果要求：点击搜索页面左上角的谷粒商城首页或谷粒商城都能跳转到商城首页。如下图：
1. 修改页面代码：（跳转路径 http://gulimall.com）
2. 测试：
点击谷粒商城首页或谷粒商城
3. 解决商城首页显示问题
server_name gulimall.com *.gulimall.com;相关命令：
# 进入gulimall.conf，修改server_name
vi gulimall.conf# 重启nginx
docker restart nginx重启nginx，访问 gulimall.com：
1.2.4 修改index.html文件名
1. gulimall-search下的index.html重命名为list.html
原因:在首页点击搜索跳转的链接为list.html
2. 新增由/list.html能跳转到list.thml页面的方法gulimall-search/src/main/java/com/wen/gulimall/search/controller/SearchController.java
@Controller
public class SearchController {@GetMapping("/list.html")public String listPage(){return "list";}
}
3. 将gulimall-product的index.html页面中的search()方法的调用由img标签放到a标签
4. 重启服务测试
1.3 检索查询参数模型分析抽取
1.3.1 检索条件分析
- 全文检索：skuTitle-》keyword
- 排序：saleCount（销量）、hotScore（热度分）、skuPrice（价格）
- 过滤：hasStock、skuPrice区间、brandId、catalog3Id、attrs
- 聚合：attrs
完整查询参数
keyword=小米&sort=saleCount_desc/asc&hasStock=0/1&skuPrice=400_1900&brandId=1&catalog3Id=1&at trs=1_3G:4G:5G&attrs=2_骁龙845&attrs=4_高清屏

1.5.1 DSL查询部分
- 属性数据类型为嵌入式，即"type"="nested"，查询、过滤也需要嵌入式。可参照官网：Nested query | Elasticsearch Guide [7.4] | Elastic
- 价格区间使用range gte lte.
1.5.1.1 查询部分DSL
# 查询部分

}1.5.2 聚合部分
1.5.2.1 聚合时出现的问题Use doc values instead
1.5.2.1.1 报错原因
1. mapping映射参数index、doc_values使用说明：
- index：index选项控制是否对字段值进行索引。它接受true或false，默认为true。如果为 false， 表示该字段不会被索引， 但是检索结果里面有， 但字段本身不能当做检索条件。
- doc_values：默认为true。如果为false，表示字段不需要进行排序、聚合、或者使用脚本访问字段值，这样可以节省磁盘空间。还可以通过设定doc_values为true，index为false 来让字段不能被检索但是可以用于排序、聚合以及脚本操作。
具体可以参照官网：mapping parameters
2. 错误原因：
brandName属性的doc_values为false不可以进行聚合。
1.5.2.1.2 解决方案
更新映射，删除映射中的index和doc_values参数。
（1）创建新的索引指定映射
PUT gulimall_product
{"mappings": {"properties": {"skuId": {"type": "long"},"spuId": {"type": "keyword"},"skuTitle": {"type": "text","analyzer": "ik_smart"},"skuPrice": {"type": "keyword"},"skuImg": {"type": "keyword"},"saleCount": {"type": "long"},"hasStock": {"type": "boolean"},"hotScore": {"type": "long"},"brandId": {"type": "long"},"catalogId": {"type": "long"},"brandName": {"type": "keyword"},"brandImg": {"type": "keyword"},"catalogName": {"type": "keyword"},"attrs": {"type": "nested","properties": {"attrId": {"type": "long"},"attrName": {"type": "keyword"},"attrValue": {"type": "keyword"}}}}}
}（2）迁移数据
# 数据迁移
POST _reindex
{"source": {"index": "product"},"dest": {"index": "gulimall_product"}
}迁移成功
（3）修改索引常量名
由product改为gulimall_product
public class EsConstant {public static final String PRODUCT_INDEX = "gulimall_product";
}1.5.2.2 聚合部分DSL
（1）DSL聚合部分

/*** 封装检索结果* @param searchParam* @param searchResponse* @return*/
private SearchResult buildSearchResponse(SearchParam searchParam, SearchResponse searchResponse) {SearchResult result = new SearchResult();// 1. 返回所有查询到的商品SearchHit[] hits = searchResponse.getHits().getHits();List<SkuEsModel> skuEsModels = new ArrayList<>();if(ArrayUtil.isNotEmpty(hits)) {for (SearchHit hit : hits) {String sourceAsString = hit.getSourceAsString();SkuEsModel skuEsModel = JSON.parseObject(sourceAsString, SkuEsModel.class);// keyword非空设置高亮if(StrUtil.isNotEmpty(searchParam.getKeyword())) {String skuTitle = hit.getHighlightFields().get("skuTitle").getFragments()[0].string();skuEsModel.setSkuTitle(skuTitle);}skuEsModels.add(skuEsModel);}}result.setProducts(skuEsModels);2. 当前所有商品涉及到的所有属性信息List<SearchResult.AttrVo> attrVos = new ArrayList<>();ParsedNested attr_agg = searchResponse.getAggregations().get("attr_agg");ParsedLongTerms attr_id_agg = attr_agg.getAggregations().get("attr_id_agg");for (Terms.Bucket bucket : attr_id_agg.getBuckets()) {// 1. 获取属性idlong attrId = bucket.getKeyAsNumber().longValue();// 2. 获取属性的名字String attrName = ((ParsedStringTerms) bucket.getAggregations().get("attr_name_agg")).getBuckets().get(0).getKeyAsString();// 3. 获取属性的值List<String> attrValues = ((ParsedStringTerms) bucket.getAggregations().get("attr_value_agg")).getBuckets().stream().map(item -> {return ((Terms.Bucket) item).getKeyAsString();}).collect(Collectors.toList());SearchResult.AttrVo attrVo = new SearchResult.AttrVo();attrVo.setAttrId(attrId);attrVo.setAttrName(attrName);attrVo.setAttrValue(attrValues);attrVos.add(attrVo);}result.setAttrs(attrVos);3. 当前所有商品涉及到的所有品牌信息List<SearchResult.BrandVo> brandVos = new ArrayList<>();ParsedLongTerms brand_agg = searchResponse.getAggregations().get("brand_agg");for (Terms.Bucket bucket : brand_agg.getBuckets()) {// 1. 获取品牌的idlong brandId = bucket.getKeyAsNumber().longValue();// 2. 获取品牌的名字String brandName = ((ParsedStringTerms) bucket.getAggregations().get("brand_name_agg")).getBuckets().get(0).getKeyAsString();// 3. 获取平品牌的图片String brandImg = ((ParsedStringTerms) bucket.getAggregations().get("brand_img_agg")).getBuckets().get(0).getKeyAsString();SearchResult.BrandVo brandVo = new SearchResult.BrandVo();brandVo.setBrandId(brandId);brandVo.setBrandName(brandName);brandVo.setBrandImg(brandImg);brandVos.add(brandVo);}result.setBrands(brandVos);4. 当前所有商品涉及到的所有分类信息ParsedLongTerms catalog_agg = searchResponse.getAggregations().get("catalog_agg");List<SearchResult.CatalogVo> catalogVos = new ArrayList<>();List<? extends Terms.Bucket> buckets = catalog_agg.getBuckets();if(CollectionUtil.isNotEmpty(buckets)){for (Terms.Bucket bucket : buckets) {SearchResult.CatalogVo catalogVo = new SearchResult.CatalogVo();// 获取分类idString keyAsString = bucket.getKeyAsString();catalogVo.setCatalogId(Long.parseLong(keyAsString));// 获取分类名称ParsedStringTerms catalog_name_agg = bucket.getAggregations().get("catalog_name_agg");String catalog_name = catalog_name_agg.getBuckets().get(0).getKeyAsString();catalogVo.setCatalogName(catalog_name);catalogVos.add(catalogVo);}}result.setCatalogs(catalogVos);//5. 分页信息 - 当前页码result.setPageNum(searchParam.getPageNum());6. 分页信息 - 总记录数long total = searchResponse.getHits().getTotalHits().value;result.setTotal(total);7. 分页信息 - 总页数Integer totalPages = (int)total%EsConstant.PRODUCT_PAGESIZE == 0?(int)total/EsConstant.PRODUCT_PAGESIZE:((int)total/EsConstant.PRODUCT_PAGESIZE + 1);result.setTotalPages(totalPages);return result;
}参数keyword不为空时，skuTitle中keyword的值设置高亮。
1.8 验证结果封装正确性
通过debug查看结果的封装。
1.9 渲染检索页面【P184-192】
（1）修改SearchParam类中库存属性hasStock不给默认值，buildSearchRequest()方法中加上库存判断，有库存，才拼接库存查询。（注意：上面的hasStock和buildSearchRequest()已经修改）
（2）要判断当前location.href是否有参数，没有以?拼接，有以&拼接。可以通过字符串的indexOf()方法进行判断，也可以通过includes()方法进行判断。具体可以参考W3C文档：https://www.w3school.com.cn/jsref/jsref_obj_string.asp
includes() ：返回字符串是否包含指定值。
indexOf() ：返回值在字符串中第一次出现的位置。
（3）搜索框回显，可以使用 th:value="${param.keyword}"完成回显功能。${param.keyword}可以获取请求参数keyword的值。
（4）分页功能完善，输入页码，点击确定，跳转到具体页面。面包屑导航：
（1）SearchResult中添加面包屑相关内容
（2）buildSearchResponse()构建查询结果里返回面包屑相关数据
（3）构建属性面包屑导航功能，因为需要属性名，所以需要远程调用gulimall-product服务1）修改search服务的pom.xml，添加spring-cloud，引入openfeign2）开启openfeign3）编写远程调用接口@GetMapping("/product/attr/info/{attrId}")public R attrInfo(@PathVariable("attrId") Long attrId);
（5）浏览器对空格的编码和Java不一样，差异化处理：

}
（6）构建品牌面包屑导航功能，因为需要品牌名称，所以需要远程调用gulimall-product服务1）编写gulimall-product服务所需品牌的接口@GetMapping("/infos")public R info(@RequestParam("brandIds") List<Long> brandIds){List<BrandEntity> brand = brandService.getBrandsByIds(brandIds);return R.ok().put("brand", brand);}2）编写远程调用接口@GetMapping("/product/brand/infos")public R brandsInfo(@RequestParam("brandIds") List<Long> brandIds);
（7）注意th:if的优先级比th:with高，可以参照 usingthymeleaf.pdf -》 Attribute Precedence1.9.1 检索页面完整代码
