我試圖使用Spring 3實現REST Remoting，但是我無法通過「406 Not Acceptable」錯誤... 我嘗試使用遠程1服務返回一個application/xml內容。每次我發送一個請求「Accept=application/xml」，我得到406錯誤。每次我發送它與一些不同的「接受」頭，我得到404（和handleNoSuchRequestHandlingMethod異常）。服務本身被調用，因爲我可以在日誌中看到它。什麼我也發現是servlet的初始化過程中出現了以下錯誤，雖然我不知道這是否是一個問題：Spring 3 REST與XML給出「406不可接受」
Did not find any ViewResolvers to delegate to; please configure them using the 'viewResolvers' property on the ContentNegotiatingViewResolver
我已經嘗試了許多不同的配置，但沒有成功。也許你可以在我的實現中發現一些錯誤？
