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

配置请求跳转

配置 Nginx 转发

配置 Windows hosts 文件：

  1. 192.168.163.131        search.gulimall.com

检索服务 - 图1
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. server {
  2.     listen       80;
  3.     server_name  gulimall.com *.gulimall.com;
  4.         ...
  5.  }

然后重启 Nginx
docker restart nginx

配置网关服务转发到 search 服务

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

配置页面跳转

配置 /list.html 请求转发到 list 模板

  1. /**
  2.  * 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
  3.  *
  4.  * @param param
  5.  * @return
  6.  */
  7. @GetMapping(value = "/list.html")
  8. public String listPage(SearchParam param, Model model, HttpServletRequest request) {
  9.     return "list";
  10. }

ES mall-product 映射 mapping修改

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。

  1. # 查看原来的映射规则
  2. GET gulimall_product/_mapping
  3. # 修改为新的映射 并创建新的索引，下面进行数据迁移
  4. PUT /mall_product
  5. {
