19.检索服务

Search模块

1.整理前端内容

导入依赖

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

html放入template目录下，静态资源放到nginx/search目录下

 配置域名转发

 

 

 想实现的效果是查询search.gulimall能访问到检索页面，在nginx中配置，不管是gulimall.com还是前面有前缀的都应该交给网关处理

 

 

 

 网关配置：

 

 

 配置热部署依赖并且配置缓存为false

  <!--  热部署依赖，使页面实时生效-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>

spring: 
 thymeleaf:
    cache: false

以后ctrl+f9就可以重新构建了

2.后台的实现（前端内容不介绍了）

实现点击三级分类跳转到list页面--检索页面

@Controller
public class SearchController {
    //转交给检索页面
    @GetMapping("/list.html")
    public String listPage(){
        return "list";
    }
}

之前映射的有错误，现在在es处迁移映射

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" }
                }
            }
        }
    }
}

POST _reindex
{
  "source": {
    "index": "product"
  },
  "dest": {
    "index": "gulimall_product"
  }
}

构建的查询条件
