步骤

public static void main(String[] args) throws IOException {
    
    
        //1.创建客户端
        RestClientBuilder clientBuilder = RestClient.builder(new HttpHost("127.0.0.1", 9200, "http"));
        RestHighLevelClient client = new RestHighLevelClient(clientBuilder);

        //2.创建请求
        DeleteRequest request = new DeleteRequest("posts", "1");

        //3.执行请求，返回响应
        DeleteResponse response = client.delete(request, RequestOptions.DEFAULT);

        String id = response.getId();
        String index = response.getIndex();

        //4.关闭客户端
        client.close();
    }
