create(org.elasticsearch.action.admin.indices.create.CreateIndexRequest, org.elasticsearch.client.RequestOptions)' is deprecated 、新的调用方式是什么

新的调用方式是使用`org.elasticsearch.client.indices.CreateIndexRequest`类代替`org.elasticsearch.action.admin.indices.create.CreateIndexRequest`类来创建索引,具体调用方式如下所示:
```java
CreateIndexRequest request = new CreateIndexRequest("index_name");
// 添加索引配置和映射等信息
request.settings(Settings.builder().put("index.number_of_shards", 3)
.put("index.number_of_replicas", 2));
request.mapping("doc",
" {\n" +
" \"properties\": {\n" +
" \"title\": {\n" +
" \"type\": \"text\"\n" +
" },\n" +
" \"content\": {\n" +
" \"type\": \"text\"\n" +
" },\n" +
" \"timestamp\": {\n" +
" \"type\": \"date\"\n" +
" }\n" +
" }\n" +
" }",
XContentType.JSON);
CreateIndexResponse response = client.indices().create(request, RequestOptions.DEFAULT);
```
可以看到,新的调用方式中,创建索引的类名和方法名都有所改变,需要使用`CreateIndexRequest`类的对象来构建请求,然后通过`client.indices().create()`方法来发送请求并获取响应。在请求对象中,可以通过`settings()`方法设置索引的配置信息,通过`mapping()`方法设置映射信息。
