RestTemplate 使用动态键映射 JSON 键值对对象 [英] RestTemplate map JSON key-value pair object with with dynamic keys

问题描述

我收到了 JSON 键值对对象的响应，其中包含使用 Java Spring RestTemplate 完成的 HTTP 请求的动态键，如下所示.

I get a response of JSON key-value pair object with with dynamic keys for a HTTP request done using Java Spring RestTemplate as shown below.

回复:

{
    "1234x": {
        "id": "1234x",
        "description": "bla bla",
        ... 
    },
    "5678a": {
        "id": "5678a",
        "description": "bla bla bla",
        ... 
    },
    ...
}

如何将响应对象映射到 POJO 或 Map ?

How to map the response object to a POJO or a Map ?

我使用 RestTemplate 如下.

I am using RestTemplate as following.

RestTemplate restTemplate = new RestTemplate();
String url = "my url";
HttpHeaders headers = new HttpHeaders();
HttpEntity entity = new HttpEntity(headers);
response = restTemplate.exchange(url, HttpMethod.GET, entity, ???);

推荐答案

您可以简单地将 ParameterizedTypeReference 与 Map 一起使用(您可以根据您的用例进行自定义):

You can simply use ParameterizedTypeReference with Map (you can customize it according to your use case) :

response = restTemplate.exchange(url, HttpMethod.GET, entity, new ParameterizedTypeReference<Map<String, Object>>() {});
