Java RestTemplate 实现接口调用并封装到 List 中

以下是使用 Java RestTemplate 实现接口调用并封装到 list 的代码：

import org.springframework.web.client.RestTemplate;

import java.util.ArrayList;
import java.util.List;

    public static void main(String[] args) {

        // 构造 Basic Auth 信息

        byte[] base64CredsBytes = Base64.getEncoder().encode(plainCredsBytes);
        String base64Creds = new String(base64CredsBytes);

        // 构造请求头
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + base64Creds);
        headers.setContentType(MediaType.APPLICATION_JSON);

        // 构造请求体
        HttpEntity<String> request = new HttpEntity<>("", headers);

代码说明：

构造 Basic Auth 信息：
- 使用 admin:admin5 作为用户名和密码，并将其转换为 Base64 编码字符串。
构造请求头：
- 将 Basic Auth 信息添加到 Authorization 头部。
- 设置 Content-Type 为 APPLICATION_JSON。
构造请求体：
- 使用空字符串作为请求体。
发送请求：
- 使用 RestTemplate 发送 GET 请求。
- 将请求 URL 设置为 http://100.71.8.94:32600/cuchulainn/openapi/asset/Pod。
- 指定返回类型为 AssetList.class。
解析响应：
- 从 response 对象中获取响应体，并获取 data 属性的 list 属性，即 Asset 对象列表。
遍历列表并打印结果：
- 遍历 Asset 对象列表，并打印每个对象的属性。

代码中使用了三个类：

AssetList： 响应体的根节点，包含 data、errorMessage、status 和 traceId 属性。
AssetData： data 属性，包含 list、total、pages 和 minorType 属性。
Asset： list 属性中每个元素的数据，包含 persistedAt、resourceId、code、description、type、uuid、projectStatus、createdAt、manageType、province、createdBy、name、shortName、reportSource、updatedAt 和 status 属性。

注意：

实际代码中需要根据接口文档修改相关参数，包括请求 URL、Basic Auth 信息、返回类型等。
为了便于理解，代码示例中省略了必要的异常处理。
