全文检索工具elasticsearch：第四章：开发电商的搜索列表功能

1、功能简介

1.1入口： 两个

首页的分类

搜索栏

      列表展示页面

2 根据业务搭建数据结构

这时我们要思考三个问题：

1. 哪些字段需要分词
2. 我们用哪些字段进行过滤
3. 哪些字段我们需要通过搜索显示出来。

第一种方式：

根据以上制定出如下结构：

执行：

PUT gmall
{
  "mappings": {
    "SkuInfo":{
      "properties": {
        "id":{
          "type": "keyword"
          , "index": false
        },
        "price":{
          "type": "double"
        },
         "skuName":{
          "type": "text",
          "analyzer": "ik_max_word"
        },
        "skuDesc":{
          "type": "text",
          "analyzer": "ik_smart"
        },
        "catalog3Id":{
          "type": "keyword"
        },
        "skuDefaultImg":{
          "type": "keyword",
          "index": false
        },
        "skuAttrValueList":{
          "properties": {
            "valueId":{
              "type":"keyword"
            }
          }
        }
      }
    }
  }
}

查看：

GET /gmall

结果：

{
  "gmall": {
    "aliases": {},
    "mappings": {
      "SkuLsInfo": {
        "properties": {
          "catalog3Id": {
            "type": "keyword"
          },
          "hotScore": {
            "type": "double"
          },
          "id": {
            "type": "keyword",
            "index": false
          },
          "price": {
            "type": "double"
          },
          "skuAttrValueList": {
            "properties": {
              "attrId": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              },
              "id": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              },
              "skuId": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              },
              "valueId": {
                "type": "keyword"
              }
            }
          },
          "skuDefaultImg": {
            "type": "keyword",
            "index": false
          },
          "skuDesc": {
            "type": "text",
            "analyzer": "ik_smart"
          },
          "skuName": {
            "type": "text",
            "analyzer": "ik_max_word"
          }
        }
      }
    },
    "settings": {
      "index": {
        "creation_date": "1548161868908",
        "number_of_shards": "5",
        "number_of_replicas": "1",
        "uuid": "1ZSLxTDOScubSqhf2c18rQ",
        "version": {
          "created": "5060499"
        },
        "provided_name": "gmall"
      }
    }
  }
}

执行测试类：

@RunWith(SpringRunner.class)
@SpringBootTest
public class GmallListServiceApplicationTests {

    @Autowired
    JestClient jestClient;

    @Reference
    SkuService skuService;
    
    @Test
    public void test02() throws IOException {
        // 查询sku表中的所有数据skuInfo
        List<SkuInfo> skuInfos = skuService.SkuListByCatalog3Id("4");

        // skuInfo转化成skuLsInfo
        for (SkuInfo skuInfo : skuInfos) {
            SkuLsInfo skuLsInfo = new SkuLsInfo();
            BeanUtils.copyProperties(skuInfo,skuLsInfo);

            // 将skuLsInfo导入到es中
            Index index = new Index.Builder(skuLsInfo).index("gmall").type("SkuLsInfo").id(skuLsInfo.getId()).build();
            jestClient.execute(index);

        }
    }

}

@Override
    public List<SkuInfo> SkuListByCatalog3Id(String catalog3Id) {

        SkuInfo skuInfo = new SkuInfo();
        skuInfo.setCatalog3Id(catalog3Id);
        List<SkuInfo> skuInfos = skuInfoMapper.select(skuInfo);

        for (SkuInfo info : skuInfos) {
            SkuAttrValue skuAttrValue = new SkuAttrValue();
            skuAttrValue.setSkuId(info.getId());
            List<SkuAttrValue> skuAttrValues = skuAttrValueMapper.select(skuAttrValue);
            info.setSkuAttrValueList(skuAttrValues);
        }
        return skuInfos;
    }

再次查看

GET /gmall/SkuLsInfo/_search

数据库中的数据就出来了

第二种方式:

之前已经将数据库中的数据保存到es中了，就可以用这种
