# 本地連接

Elasticsearch docker 透過 Spring 實做本地連接功能

---

## 一、依賴項

<dependency>
    <groupId>org.elasticsearch.client</groupId>  
    <artifactId>elasticsearch-rest-client</artifactId>  
    <version>7.12.0</version>  
</dependency>

## 二、寫入資料

// 建立連線端  
RestClient restClient = RestClient.builder(
        new HttpHost("localhost", 9200, "http")).build();  

// 設定路徑  
Request request = new Request(  
        "post",  
        "/hktv/product");  
// 組資料
request.setJsonEntity("{\"invisible\":true}");

// 送出  
Response response = restClient.performRequest(request);
