ElasticSearch索引mapping添加字段-java_elasticsearch mapping 增加字段

在已存在的索引mapping中添加字段,基于es7.17.6

java代码如下

private static void putMapping() {
        try {
            // 创建PutMappingRequest对象
            PutMappingRequest request = new PutMappingRequest(indexName);

            // 定义字段的映射
            String mappingJson = "{" +
                    "  \"properties\":{" +
                    "      \"field_name\": {" +
                    "        \"type\": \"keyword\"" +
                    "      }" +
                    " }"
            // 将JSON字符串添加到请求中
            request.source(mappingJson, XContentType.JSON);


            // 发送请求更新映射
            client.indices().putMapping(request, RequestOptions.DEFAULT);

            System.out.println("Mapping updated successfully");
