Spring JSTL標記不起作用

我使用spring roo生成web項目。我設置的Web MVC框架，通過使用web mvc setup後，Web應用程序文件夾具有以下結構：Spring JSTL標記不起作用

.../webapp/ 
     | 
     |_images 
     |_styles 
     |_WEB-INF 
      | 
      |_classes 
      |_i18n 
      |_spring 
      |_layouts 
      |_tags 
      | |_form 
      | |_menu 
      | |_util 
      | 
      |_views 
      |_web.xml

，我把佈局，圖片，樣式和標記文件夾到的意見文件夾（因爲我有這個其他意見項目，我不想把它們搞亂），並且我更改了views.xml中的相關路徑以及* .jspx文件中的所有標記路徑。這是更改後的文件的樣子。

文件結構

.../webapp/ 
     | 
     |_WEB-INF 
      | 
      |_classes 
      |_i18n 
      |_spring 
      | 
      |_views 
      | |_images 
      | |_layouts 
      | |_styles 
      | |_tags 
      |  |_form 
      |  |_menu 
      |  |_util 
      |_web.xml

web的mvc.xml

    <mvc:view-controller path="/logout"/>

我只是忽視其他JSPX文件，如頁眉，頁腳等等，因爲我剛換的一部分該文件即「xmlns:util="urn:jsptagdir:/WEB-INF/tags/util"」，並將其更改爲「xmlns:util="urn:jsptagdir:/WEB-INF/views/tags/util"」。

現在我運行mvn clean install和mvn clean tomcat:run，項目可以構建並部署到tomcat服務器中，沒有任何錯誤。當我訪問瀏覽器的主頁時，我總是得到以下錯誤。

我使用我的整個一天谷歌的解決方案，我什麼也沒有得到。如果我保留由spring roo生成的默認結構，一切都很好。所以我確信當我更改配置文件時我必須做錯事，但我找不到它。

有沒有人可以幫助我呢？

非常感謝你提前！

不要打你的工具。原始組織並不完全是Roo特有的，但它是由Java Web標準定義的。

WEB-INF內的任何東西都不能直接訪問公衆，圖像和樣式應該保持在外面。
標籤文件在Java Web標準中也有特定的位置。
佈局由Apache Tiles處理，所以我不確定它們的位置是否受限制。

基於madth3說我做了進一步的搜索和實驗，我發現圖像，樣式和佈局的位置都很好，因爲如果我將WEB-INF文件夾下的標籤文件夾移動到WEB -INF/views，項目運行良好。後來，我做了另一次搜索，發現我無法更改標籤文件夾位置的原因是因爲spring roo使用「urn：jsptagdir」來定義taglib uri。因此，如果想要更改標籤位置，只需刪除「urn：jsptagdir」，然後使用普通URI。原因如下（http://download.oracle.com/javaee/1.4/tutorial/doc/JSPX3.html）。 – charles
