一、添加模板页面

1
2
3
4
5
<!-- 模板引擎 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

将资料中的前端页面放到 search 服务模块下的 resource/templates 下;

image-20210824225137968

二、配置请求跳转

1、配置 Nginx 转发

配置 Windows hosts 文件:

1
192.168.56.10	search.gulimall.com

image-20210824230058346

找到 Nginx 的配置文件,编辑 gulimall.conf,将所有 *.gulimall.com 的请求都经由 Nginx 转发给网关;

1
2
3
4
5
server {
listen 80;
server_name gulimall.com *.gulimall.com;
...
}

然后重启 Nginx

1
docker restart nginx

2、配置网关服务转发到 search 服务

1
2
3
4
- id: gulimall-search
uri: lb://gulimall-search
predicates:
- Host=search.gulimall.com

image-20210824231648262

3、静态页面处理

  • 把资料中的前端页面的css、img、js 放到nginx的static目录下

image-20210824232059503

  • 修改gulimall-search 项目中index.html中的资源路径

例如:

image-20210824233316515

image-20210824233340069

4、配置页面跳转

第一处: gulimall-search index.html

image-20210825000123002

第二处:gulimall-search index.html

image-20210825000209003

配置 /list.html 请求转发到 list 模板

/**
* 自动将页面提交过来的所有请求参数封装成我们指定的对象
*
* @param param
* @return
*/
@Controller
public class SearchController {

@GetMapping("/list.html")
public String listPage(){
return "list";
}
}

image-20210825002935226

image-20210825002958192

image-20210825003015834

三、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

// 排序条件: sort=price/salecount/hotscore_desc/asc
private String sort;

// 是否显示有货
private Integer hasStock;

// 价格区间查询
private String skuPrice;

// 按照属性进行筛选
private List<String> attrs;

// 页码
private Integer pageNum = 1;

// 原生的所有查询条件
private String _queryString;
}

2、返回结果

private String attrName;
private List<String> attrValue;
}

@Data
@AllArgsConstructor
public static class CatalogVo{

}
}

六、检索功能

1、ES mall-product 映射 mapping修改

注意:这里由于之前设置的映射 设置一些字段的 doc_value 为 false,导致后面聚合查询时报错!修改完映射 mapping 要同步修改检索服务中的常量类中的 es 索引常量,二者要求对应。

3、 分页数据渲染

将页码绑定至属性pn,当点击某页码时,通过获取pn值进行url拼接跳转页面

<div class="filter_page">
<div class="page_wrap">
<span class="page_span1">
<!-- 不是第一页时显示上一页 -->
<a class="page_a" href="#" th:if="${result.pageNum>1}" th:attr="pn=${result.getPageNum()-1}">
< 上一页
</a>
<!-- 将各个页码遍历显示,并将当前页码绑定至属性pn -->
<a href="#" class="page_a"
th:each="page: ${result.pageNavs}"
th:text="${page}"
th:style="${page==result.pageNum?'border: 0;color:#ee2222;background: #fff':''}"
th:attr="pn=${page}"
>1</a>
<!-- 不是最后一页时显示下一页 -->
<a href="#" class="page_a" th:if="${result.pageNum<result.totalPages}" th:attr="pn=${result.getPageNum()+1}">
下一页 >
</a>
</span>
<span class="page_span2">
<em><b th:text="${result.totalPages}">169</b>&nbsp;&nbsp;到第</em>
<input type="number" value="1" class="page_input">

<a href="#">确定</a>

$(".page_a").click(function () {
var pn=$(this).attr("pn");
location.href=replaceParamVal(location.href,"pageNum",pn,false);
console.log(replaceParamVal(location.href,"pageNum",pn,false))
})

4、 页面排序和价格区间

页面排序功能需要保证,点击某个按钮时,样式会变红,并且其他的样式保持最初的样子;

点击某个排序时首先按升序显示,再次点击再变为降序,并且还会显示上升或下降箭头

页面排序跳转的思路是通过点击某个按钮时会向其class属性添加/去除desc,并根据属性值进行url拼接
