本文介绍如何使用Elasticsearch的get API来获取特定ID的JSON文档。默认情况下，API提供实时数据，即使文档未被刷新也能确保可见。可以设置realtime参数为false以禁用实时功能。此外，通过_query参数可以控制是否返回_source字段内容。

示例：

GET /spring-elasticsearch-demo/person/1 HTTP/1.1
Host: localhost:9200
Content-Type: application/json
cache-control: no-cache
Postman-Token: 5b200229-505b-45bb-9349-a2b23e1d8e67

{
    "_index": "spring-elasticsearch-demo",
    "_type": "person",
    "_id": "1",
    "_version": 4,
    "found": true,
    "_source": {
        "id": "1",
        "name": "天天向左",
        "description": "这是天天向下",
        "age": 24,
        "create": 1535760000001
    }
}

GET /spring-elasticsearch-demo/person/4 HTTP/1.1
Host: localhost:9200
Content-Type: application/json
cache-control: no-cache
Postman-Token: 07a70aea-c212-4868-ac84-49aeee0752ff

{
    "_index": "spring-elasticsearch-demo",
    "_type": "person",
    "_id": "4",
    "found": f
