当与Spring MVC和JSON一起使用时,我一直收到AJAX请求的HttpMediaTypeNotAcceptableException错误.错误的完整堆栈跟踪是..

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:

public class HttpClientDemo {

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