我正在尝试使用 Spring 3 实现 REST Remoting，但我无法通过“406 Not Acceptable”错误...我尝试远程 1 服务返回应用程序/xml 内容。每次我使用“”发送请求时Accept=application/xml，都会收到 406 错误。每次我用一些不同的“Accept”标头发送它时，我都会得到 404（和 handleNoSuchRequestHandlingMethod 异常）。正如我在日志中看到的那样，服务本身被调用。我还发现，在 servlet 初始化期间，我收到以下错误，尽管我不确定这是否是一个问题：
没有找到任何要委托给的 ViewResolver；请使用 ContentNegotiatingViewResolver 上的“viewResolvers”属性配置它们
我尝试了许多不同的配置，但没有成功。也许您可以在我的实现中发现一些错误？
