20 RestClient 操作索引库

20.4 创建索引库

20.4.1 创建索引库

步骤4：创建索引库

创建索引库代码如下：

试试

先来一个常量类，存放json 语句

package cn.itcast.hotel.constants;

/**
 * ClassName: HotelConstants
 * date: 2022/11/1 10:16
 *
 * @author DingJiaxiong
 */


public class HotelConstants {

    public static final String MAPPING_TEMPLATE = "{\n" +
            "  \"mappings\": {\n" +
            "    \"properties\": {\n" +
            "      \"id\":{\n" +
            "        \"type\": \"keyword\"\n" +
            "      },\n" +
            "      \"name\":{\n" +
            "        \"type\": \"text\",\n" +
            "        \"analyzer\": \"ik_max_word\"\n" +
            "      },\n" +
            "      \"address\":{\n" +
            "        \"type\": \"keyword\",\n" +
            "        \"index\": false\n" +
            "      },\n" +
            "      \"price\":{\n" +
            "        \"type\": \"integer\"\n" +
            "      },\n" +
            "      \"score\":{\n" +
            "        \"type\": \"integer\"\n" +
            "      },\n" +
            "      \"brand\":{\n" +
            "        \"type\":\"keyword\"\n" +
            "      },\n" +
            "      \"city\":{\n" +
            "        \"type\": \"keyword\"\n" +
            "      },\n" +
            "      \"starName\":{\n" +
            "        \"type\": \"keyword\"\n" +
            "      },\n" +
            "      \"business\":{\n" +
            "        \"type\": \"keyword\"\n" +
            "      },\n" +
            "      \"location\":{\n" +
            "        \"type\": \"geo_point\"\n" +
            "      },\n" +
            "      \"pic\":{\n" +
            "        \"type\": \"keyword\",\n" +
            "        \"index\": false\n" +
            "      }\n" +
            "    }\n" +
            "  }\n" +
            "}";

OK，编写测试方法

//创建索引库
@Test
void createHotelIndex() throws IOException {
    //1. 创建Request对象
    CreateIndexRequest request = new CreateIndexRequest("hotel");

    //2. 准备请求的参数：DSL 语句
    request.source(MAPPING_TEMPLATE, XContentType.JSON);

    //3. 发送请求
    client.indices().create(request , RequestOptions.DEFAULT);
}
