Spring主题与REST不兼容

Question

我已经试着解决这个问题好几天了，我在论坛上也找不到任何有类似问题的帖子。当我将servlet映射url模式设置为*时，Spring主题运行良好。web中的html。xml文件。但是，如果我更改web中的url模式。将xml文件改为正斜杠，以便默认servlet处理所有请求，并且URL可以看起来像REST URL，然后我使用它来获得无映射错误，这导致无法显示网页的css设置。我用来获取的无映射警告如下：

WARN http-apr-8080-exec-6 (DispatcherServlet.java:947) - No mapping found for HTTP request with URI [/MyApp/themes/default.css] in DispatcherServlet with name 'spring'.

但在通过添加到我的Spring servlet配置文件来解决映射问题时：

<mvc:default-servlet-handler />  

出现了另一个问题：现在，在应用程序启动后和任何操作之前，在任何REST操作之前单击主题选项的使用效果很好。这一切都很好地展示了正确的主题。事实上，如果我通过正常的控制器（没有REST）进行非REST操作，一切都会继续正常工作，我可以在主题之间切换。然而，在通过REST访问时，在单击主题时，即使它返回的视图名称与正常控制器返回的视图名称相同，我在浏览器中也会出现以下错误，奇怪的是，没有报告控制台（调试）消息：

    HTTP Status 405 - Request method 'GET' not supported

    type Status report

    message Request method 'GET' not supported

    description The specified HTTP method is not allowed for the requested resource (Request method 'GET' not supported).

最后，我的主题属性文件位于

LiveAppSpring\src\main\resources 

所有主题属性文件的内容具有以下模式：

css=themes/default.css 

为了安全起见，我在所有3个目录中复制了css文件：

LiveAppSpring\src\main\webapp\resources

LiveAppSpring\src\main\webapp\resources\themes 

LiveAppSpring\src\main\webapp\themes 

任何指示将不胜感激。

Answer 1

我希望/MyApp/主题/default.css应该提供default.css。但这是一个资源文件，您通过

 <mvc:resources mapping="/resources/**" location="/resources/" />

因此，正确的请求url应该是MyApp/resources/default。css（假设默认.css位于webapp/resources/default.css中）
