- Springboot整合ElasticSearch
a、提前使用kibana创建索引和字段类型// 创建索引 PUT /tradeindex // 创建字段类型 POST /tradeindex/_mapping/trade { "trade": { "properties": { "name": { "type": "text", "analyzer": "ik_smart" }, "desc": { "type": "text", "analyzer": "ik_smart" }, "price": { "type": "double" }, "createTime": { "type": "long" }, "storeName": { "type": "keyword" }, "storeAddress": { "type": "keyword" } } } }// 记住类型要设置'text'，且搜索引擎设置ik_smart，否则不会进行分词
b、创建好数据
### 3、创建商品数据 POST /tradeindex/trade { "name": "白色耳机", "desc": "经典白色耳机", "price": "15.6", "createTime": 1567043300836, "storeName": "唯品会", "storeAddress": "安徽省合肥市" } POST /tradeindex/trade { "name": "蓝色耳机", "desc": "经典蓝色耳机", "price": "16.6", "createTime": 1567043400836, "storeName": "平多多", "storeAddress": "安徽省六安市" } POST /tradeindex/trade { "name": "红色蓝牙耳机", "desc": "经典红色蓝牙耳机", "price": "17.6", "createTime": 1567043400836, "storeName": "美团", "storeAddress": "江西省九江市" } POST /tradeindex/trade { "name": "白色蓝牙耳机", "desc": "经典白色蓝牙耳机", "price": "18.6", "createTime": 1567043400836, "storeName": "滴滴", "storeAddress": "江西省九江市" } POST /tradeindex/trade { "name": "黑色蓝牙无线耳机", "desc": "经典黑色蓝牙无线耳机", "price": "18.6", "createTime": 1567043400836, "storeName": "京东", "storeAddress": "江西省赣州市" } POST /tradeindex/trade { "name": "白色蓝牙无线耳机", "desc": "经典白色蓝牙无线耳机", "price": "18.6", "createTime": 1567043400836, "storeName": "淘宝", "storeAddress": "江西省南昌市" } // 查询所有数据 GET /tradeindex/trade/_search
- 创建springboot项目，在pom.xml中引入依赖
