Spring RestTemplate 无法转换 json 响应 [英] Spring RestTemplate can not convert json response

问题描述

我有网址 - http://hzhzhz

返回json

{
    "someField": 3,
    "datesField": ["2017-08-19",
    "2017-08-20",
    "2017-08-26",
    "2018-12-30"]
}

我创建模型

@Data
@NoArgsConstructor
private class Response{
    private int someField;
    private DatesField datesField;
}

@Data
@NoArgsConstructor
private class DatesField{
    private List<String> strings;
}

我创造

ResponseforObject = restTemplate.getForObject("http://hzhzhz", Response.class);

我得到错误:

Could not extract response: no suitable HttpMessageConverter found for response type [class mypackeg.Response] and content type [text/html;charset=utf-8]

推荐答案

您的 "http://hzhzhz" 调用返回无法转换为 mypackeg.Response 类的 HTML.

Your "http://hzhzhz" call returns HTML which cannot be converted to the mypackeg.Response class.

可能是 URL 错误或产生错误的内容类型(HTML 而不是预期的 JSON 或 XML).要修复尝试返回 String.class 并检查字符串中的确切内容.

Could be URL is wrong or it produces wrong content type (HTML instead of expected JSON or XML). To fix try to return String.class and check what exactly in the string.

另一个可能的原因是权限被拒绝，它返回访问被拒绝的 HTML 页面.

One more possible reason is permission denied which returns access denied HTML page.
