dynamic json response: Could not read JSON: N/A (through reference chain) Hymanson fasterxml
提问by Sven Deckers
I want to access a REST api with a variable amount of product codes as parameters. The JSON response will give me a token for every code I submit.
我想使用可变数量的产品代码作为参数访问 REST api。JSON 响应将为我提交的每个代码提供一个令牌。
The problem is the root elements of the json response will be the product codes I submitted, so I can't use the standard @JsonProperty annotation in my receiving class.
问题是 json 响应的根元素将是我提交的产品代码，所以我不能在我的接收类中使用标准的 @JsonProperty 注释。
How to go about this ?!
这怎么办？！
For instance: URL: http://example.com/listing?code=123456&code=456789
例如：网址：http: //example.com/listing?code=123456&code=456789
Response:
{
"123456": {
"code": 123456,
"primaryToken": "4176d70b52c3f3287c7"
},
"456789": {
"code": 456789,
"primaryToken": "6ddsd25a36bdf7fb"
}
}
I call the API like this :
我这样调用 API：
ImageListingResponse response = restTemplate.getForObject(url, ImageListingResponse.class, apiArguments);
And my ImageListingResponse class is :
我的 ImageListingResponse 类是：
@JsonIgnoreProperties(ignoreUnknown=true)
public class ImageListingResponse {
private Map<String, ImageResponse> response;
@JsonAnyGetter
public Map<String,ImageResponse> get() {
return response;
}
@JsonAnySetter
public void set(String name, ImageResponse value) {
response.put(name, value);
}
}
ImageResponse :
图像响应：
@JsonIgnoreProperties(ignoreUnknown=true)
public class ImageResponse {
@JsonProperty("code")
private Long code;
@JsonProperty("primaryToken")
private String primaryToken;
...
}
Thanks in advance !
提前致谢 ！

采纳答案by Alexey Gavrilov
Isn't it just because you didn't initialize the Map<String, ImageResponse> responsefield?
不是因为你没有初始化Map<String, ImageResponse> response字段吗？
