在Java REST Client [ 6.5 ] API上使用ES 6.5中的映射创建索引

RestHighLevelClient client = new RestHighLevelClient(
        RestClient.builder(new HttpHost("localhost", 9200, "http")));

CreateIndexRequest request = new CreateIndexRequest("index_name");

request.mapping("",
        "  {\n" +
        "    \"properties\": {\n" +
        "      \"field1\": {\n" +
        "        \"type\": \"text\"\n" +
        "      },\n" +
        "      \"field2\": {\n" +
        "        \"type\": \"keyword\"\n" +
        "      }\n" +
        "    }\n" +
        "  }",
        XContentType.JSON);

CreateIndexResponse response = client.indices().create(request, RequestOptions.DEFAULT);

if (response.isAcknowledged()) {
    System.out.println("索引创建成功");
} else {
    System.out.println("索引创建失败");
}
