我是Spring的新成员,并在Spring集成http模块中工作,以满足我的项目需求.我从出站网关发送请求作为http客户端.我正在尝试向服务器发起请求,服务器应该使用我的设置值返回消息有效负载.我正在将对象转换为JSON使用发送到服务器我正在从客户端(HttpClientDemo)向服务器端的入站网关发送请求,如下所示.为此,我将我的对象转换为JSON,然后在客户端转换为JSON字符串到对象,在那里执行一些简单的操作并将其发送回客户端(HttpClientDemo)但在此之前,我得到与之相关的异常HttpMessageConverter如下:

Exception in thread "main" org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [class com.mycompany.MyChannel.model.FFSampleResponseHttp] and content type [text/plain;charset=UTF-8]

请在下面找到相关代码:

客户端代码:HttpClientDemo.java

public class HttpClientDemo {

    private static Logger logger = Logger.getLogger(HttpClientDemo.class);
    public static void main(String[] args) {
        ApplicationContext context = …

Web API 正在响应带有 的请求Content-Type:text/plain; charset=utf-8，但消息的格式就像 JSON 一样，例如。

{
"total": 168,
"page": 0,
"pageCount": 1,
...
}

在 Spring 中，此消息使用 RestTemplate 进行处理，并且 JSON 会自动映射到ModelDtoPOJO，

restTemplate.getForObject(url, ModelDto::class.java) 

这会产生以下错误：

org.springframework.web.client.RestClientException：无法提取响应：没有找到适合响应类型 [class api.ModelDto] 和内容类型 [text/plain;charset=utf-8] 的 HttpMessageConverter

尽管 Content-Type 是纯文本，有什么方法可以让 spring 将此消息视为 JSON 并对其进行解析？
