//初始化ES鏈接：

static RestHighLevelClientrhlclient =new RestHighLevelClient(

RestClient.builder(

new HttpHost("localhost", 9200, "http")));

Get Mapping API:

GetMappingsRequest request = new GetMappingsRequest();

GetMappingsResponse getMappingResponse = rhlclient.indices().getMapping(request, RequestOptions.DEFAULT);

ImmutableOpenMap> allMappings = getMappingResponse.mappings();

?MappingMetaData typeMapping = allMappings.get(INDEX_NAME).get(TYPE_NAME);

//獲得Mapping

?Map<String, Object> mapping = typeMapping.sourceAsMap();

Put Mapping API：

String json =null;

String fileName = GetElasticSearchMappingsMain.class.getClassLoader().getResource("resourceName").getPath();? ??

json =readJsonData(fileName);

String jsonObject = JSONObject.parseObject(json).toJSONString();

PutMappingRequest mappingRequest =new PutMappingRequest(INDEX_NAME);

mappingRequest.type(TYPE_NAME);

mappingRequest.source(json, XContentType.JSON);

PutMappingResponse putMappingResponse =rhlclient.indices().putMapping(mappingRequest,RequestOptions.DEFAULT);

boolean acknowledged = putMappingResponse.isAcknowledged();
