Resthighlevelclient gets the mapping of an index

Reference code ：

// Build request 
GetMappingsRequest request = new GetMappingsRequest().indices(" Index name ");
// Use RestHighLevelClient Initiate request 
GetMappingsResponse response = restHighLevelClient.indices().getMapping(request, RequestOptions.DEFAULT);

Get GetMappingsResponse After this response data , How to process and obtain the data , Reference code ：

Map<String, MappingMetaData> mappingMap = response.mappings();
MappingMetaData indexMapping = mappingMap.get(" Index name ");
Map<String, Object> mapping = indexMapping.sourceAsMap();

The above is to provide a reference for use , Improve efficiency , It doesn't work , Through the above code , We can roughly obtain the required data , What to do next , Make a break , Look at the structure of the returned data , Just pick it up on demand .
