Not able to create index using Java high level Rest client

Question

I am using java high level rest client for integrating elasticsearch in my application,But not able to create an index

somewhere I found that to execute the request we need to use index(request) method (which I have commented in my code) but it is shwing that index(request) method is deprecated from the type RestHighLevelClient.

Here is my code:

@GetMapping("/createIndex")
public boolean createIndex() throws IOException {


    IndexRequest request = new IndexRequest(
            "muviuser", 
            "user",  
            "1");   
    String jsonString = "{" +
            "\"user\":\"Bran\"," +
            "\"postDate\":\"2018-01-30\"," +
            "\"message\":\"trying out Elasticsearch\"" +
            "}";
    request.source(jsonString, XContentType.JSON);

    //client.index(request);
}

As the documentation explains, here's how to create an index using the high-level ES API:

    CreateIndexRequest request = new CreateIndexRequest(indexName);
    request.mapping("_doc", mappingJson, XContentType.JSON);
    CreateIndexResponse response = client.indices().create(request);

Note that your source document looks wrong, as it needs to follow the specific ES request format with mappings, settings and aliases. Better to specify just the mapping instead.

That no longer seems to be accurate, a CreateIndexRequest no longer accepts a document type argument.

My post applies to ES 6.0. However, it still worked when I tried with ES 7.1.0.
