有人能帮助我解析json字符串对象，我尝试，但总是得到这样的错误：

Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 3 path $[0]

下面是我的代码：
项目类别：

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Item{

    @JsonProperty("id")
    String id;
    
    @JsonProperty("dTime")
    long dTime;
    
    @JsonProperty("aTime")
    long aTime;
}

将json转换为对象：

String jsonString = "[
    [
        {
            "id":"string",
            "dTime": 1111111111,
            "aTime": 1111111111
        },
        {
            "id":"string",
            "dTime": 1111111111,
            "aTime": 1111111111
        }
    ]
]";
Gson gson = new Gson();
Type listType = new TypeToken<List<Item>>() {}.getType();
List<Item> list = gson.fromJson(jsonString, listType);

System.out.println(gson.toJson(list));

• • 更新：**因为我从外部API获得了此json作为响应：

ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, request, String.class);

Is it possible to make this converting to Array of Item objects inside this restTemplate.exchange(..) or this with gson is better way?
