elasticsearch - JAVA的createIndex elasticsearch高级REST客户端错误地进行了设置

Question

我正在使用elasticsearch documentation中的这段代码来创建索引。我应该能够将Postman中的索引配置对象粘贴到我的Java代码中。

request.source("{\n" +
        "    \"settings\" : {\n" +
        "        \"number_of_shards\" : 1,\n" +
        "        \"number_of_replicas\" : 0\n" +
        "    },\n" +
        "    \"mappings\" : {\n" +
        "        \"properties\" : {\n" +
        "            \"message\" : { \"type\" : \"text\" }\n" +
        "        }\n" +
        "    },\n" +
        "    \"aliases\" : {\n" +
        "        \"twitter_alias\" : {}\n" +
        "    }\n" +
        "}", XContentType.JSON); 

当我执行GET / index_name时，我看到一个具有奇怪结构的索引，其中包含两个映射部分。为什么是这样？我希望有一个映射和一个设置部分。

{
    "contacts_4_3t88f9nabk": {
        "aliases": {},
        "mappings": {
            "properties": {
                "aliases": {
                    "properties": {
                        "twitter_alias": {
                            "type": "object"
                        }
                    }
                },
                "mappings": {
                    "properties": {
                        "properties": {

                                            "fields": {

                                                    "ignore_above": 256
                                                }
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    }
                },
                "settings": {
                    "properties": {
                        "number_of_replicas": {

                        },
                        "number_of_shards": {
                            "type": "long"
                        }
                    }
                }
            }
        },
        "settings": {
            "index": {

我需要使用CreateIndexRequest对象而不是IndexRequest。
